Purdue Stories: This amphibious rock star gets its own educational video game with the help of Purdue research.
The eastern hellbender salamander will never win a wildlife beauty pageant. It’s believed that it got its name from settlers who said it looked like a creature from hell that was “hell-bent” on going back there. But it turns out that the hellbender could probably win the pageant’s talent contest because of all the good it does for the ecosystem.
Purdue research has revealed that the hellbender is one salamander that just might capture your heart.
Once endangered in Indiana and at risk in other parts of America, the hellbender does so much good that it inspired its own custom-built Minecraft experience. Yes, Minecraft — the one with its own movie starring Jack Black and Jason Momoa, and millions of players from every single country worldwide.
Helped by Boilermaker researchers first organized by Rod Williams, a former Purdue professor now on the faculty at Texas Tech University, “Help the Hellbender — A Minecraft Conservation Quest” was created for the Minecraft Education realm.

This new game lets players traverse the hellbender’s underwater world, overcoming challenges and learning about why we all need to protect this superstar amphibian, whose health helps reveal the health of rivers and streams.
With millions of young Minecraft lovers around the world, the game is an ideal vehicle to reach middle schoolers and high schoolers — its target audiences.
It’s hoped that those students will discover not only a fascination with this lovable amphibian, but also a sense of environmental stewardship.
Roni Bullock, a senior Purdue Extension educator and forestry and natural resources graduate student, who has written lesson plans for teachers to use in combination with the game, says she sees the Minecraft game-based learning experience as a digital adventure that connects young minds to the living systems that sustain them.
“The hellbender might not look glamorous,” she says with a laugh, “but once you get to know it, you realize how much it tells us about the health of our rivers and streams. It’s a perfect species to show why protecting water matters.”
A living water-quality monitor
Looking like very slimy, super-overgrown tadpoles — their unique nicknames include “snot otter” and “water dog” — hellbenders can grow up to 2 feet long and weigh nearly 5 pounds.
You might notice that the hellbender’s wrinkly skin looks a bit like wet lasagna noodles. That’s because it lives underwater and breathes through its skin. This also is a main reason it’s so vital to humans. Because it absorbs oxygen through its skin, it’s a living water-quality monitor — a sentinel — for the health and purity of waterways.
When hellbenders get sick or fail to reproduce, water conservationists know they need to figure out what’s wrong with their watery habitat and then work to fix it.
Jason Hoverman, professor of vertebrate ecology in the Department of Forestry and Natural Resources in Purdue’s College of Agriculture, says hellbenders are coming back in Indiana after their numbers were estimated at less than 1,000 before 2010. He says their comeback story is all about teamwork.
“We’ve released over 1,000 hellbenders into Indiana streams in the last decade and, just two summers ago, we found the first evidence that they’re reproducing again,” he says. “That was huge. It meant the population was not just surviving — it was recovering.”

The hellbender makes a comeback
The recovery is no accident. “It’s been a massive partnership,” Hoverman says. “We work with the Indiana Department of Natural Resources, several zoos and nonprofits. Everyone’s doing their part to make sure this species has a future.”
The collaboration even stretches beyond Indiana, linking scientists and conservationists across more than a dozen states in the hellbender’s range from New York to Georgia.
Hoverman and his team study the eastern hellbender, found mostly in the cold, rocky streams of southern Indiana near the Kentucky border. “They used to be found farther north,” he says, “but as water quality declined and habitats changed, their range shrank.”
Today, much of the work focuses on protecting and restoring those last strongholds — particularly the Blue River, where Purdue scientists monitor conditions closely. “It’s encouraging; overall, the water quality there has really improved,” Hoverman says.
But the battle isn’t over. Farming practices that strip soil from fields can send clouds of mud into streams, filling in the under-rock crevices where hellbenders stay hidden from predators and protect their eggs.
“If you have bare farm fields and heavy rain, that soil can just slide into the river,” Hoverman says. “It’s like a mudslide filling in all the spaces they need to live.” He says the solution can be surprisingly simple: planting cover crops and buffer strips of trees at the edges of farm fields to retain soil and nutrients. “Those practices help farmers, too — they conserve soil and nutrients, so everyone wins.”
Hoverman sees the hellbender as an essential messenger: “When hellbenders are thriving, it means our water is clean enough for us to thrive, too. If we take care of them, we’re really taking care of ourselves.”

Learning species conservation through play
When Minecraft’s virtual gaming platform enables players to dive into the world of the hellbender, Bullock wants to make sure those players resurface with a purpose.
“When they play, students get to experience three different roles,” Bullock says. “They’ll choose to be a wildlife biologist working in the field, a lab researcher helping raise hellbenders in captivity or a conservationist collaborating with local landowners. And at the end, they can actually become the hellbender itself, experiencing how human activities affect its world.”
By taking on those roles, players will experience the problems as well as the possibilities. “I want students to see that people really do have an impact on the environment around them,” Bullock says. “But I also want them to feel empowered — to realize that they can make a difference. Whether it’s through farming practices that prevent runoff or by pursuing careers in conservation biology, these are all ways to help protect wildlife and clean water.”
Bullock’s lesson plan will become part of Purdue Extension’s signature curriculum for teachers nationwide — and even internationally.
“It’s free for teachers everywhere, and anyone can download it,” Bullock says. “The lesson I’ve written is designed to pair with the game so that teachers can engage students and draw out the key concepts afterward.”
Her lesson plan will soon be available on Purdue Extension’s Nature of Teaching website as well as the Help the Hellbender homepage. “We want it to be easy; just click, play and learn,” Bullock says.
For the Purdue scientists behind the project, the goal extends far beyond the screen. Every student who plays and every teacher who shares the lesson helps build a generation that values clean water, resilient ecosystems, and the intriguing and mysterious creatures that depend on them.
As Bullock puts it, “If the hellbender can inspire even a few students to care about conservation, then that’s a win for everyone — including the rivers we all share.”

The Natural Resources Conservation Service (NRCS) highlights a powerful example of how conservation practices on working lands can support both farm productivity and wildlife habitat in their recent story, Restoring Roots to Save the Salamanders.
On a stretch of farmland in southern Indiana, deep ruts once cut through fields so severely that, as landowner Ben Shireman recalls, “we had ditches in the field that you could park pickup trucks in.” Years of continuous row cropping by a previous owner had taken a toll on the land, leaving behind eroded hillsides, depleted soils and a system that was no longer sustainable both economically and environmentally. What followed for the Shireman family was not a quick fix. It was a transformation rooted in conservation, partnership and a willingness to rethink how their land could work for them and the environment around them.
Today, that same farm is a small but vital part of a growing effort to improve water quality and restore habitat for one of Indiana’s most unique aquatic species called the Eastern Hellbender.
Read how one southern Indiana farm transformed degraded soils and severe erosion into a more resilient system through conservation practices and partnerships here: Restoring Roots to Save the Salamanders.
At the center of this effort is the Farmers Helping Hellbenders initiative, a Regional Conservation Partnership Program (RCPP) focused on improving water quality in the Blue River watershed while supporting habitat for the Eastern Hellbender, one of Indiana’s most unique aquatic species. By implementing practices like rotational grazing, cover crops and nutrient management, farmers can improve soil health and contribute to cleaner waterways that benefit both agriculture and wildlife.
This story highlights how targeted conservation programs and local collaboration can create lasting impacts, helping farms remain productive while protecting natural resources for future generations. It also emphasizes the importance of outreach, technical assistance and farmer-led innovation in building more sustainable systems across Indiana landscapes.

The aquaculture industry in the Midwest region of the United States has limited or no access to economically feasible seafood processing infrastructure for farmed seafood products, leaving producers to rely on live ethnic fish and recreational markets. This handbook highlights the necessary elements of processing fish to guide any interested fish farmer or entrepreneur.
Local kitchens, such as shared-use commercial kitchens and licensed on-farm kitchens, can provide resources for fish farming entrepreneurs interested in adding some form of value to their fish, by allowing them to diversify their market. These shared-use commercial kitchens can be found in many communities and are rented by food producers, local food entrepreneurs, and caterers to prepare and process their food products for consumer markets. Using local facilities for processing fish and developing aquaculture products could diversify marketing opportunities for small-scale fish farmers and have a positive impact on farm profitability. A diversified market also reduces market risks for fish farmers. Embarking on processing is an additional investment for a fish farmer and requires resources.
This handbook provides some information and resources for fish farmers interested in using licensed kitchen facilities for fish processing or setting up their own on-farm processing kitchen. This handbook highlights the necessary elements of processing fish to guide any interested fish farmer or entrepreneur.

Illinois-Indiana Sea Grant (IISG) has recently added to its YouTube Channel new water safety videos, which share what to watch for and how to stay out of those scary situations that can become dangerous very quickly.
Water Safety Basics: Water safety is more then just knowing how to swim. You need to what can cause hazards, what type of water bodies have hazards and how to avoid or survive those hazards.
Water Safety – What to Know Before You Go to the Beach: On average every year, 87 people die in the Great Lakes, half of them are in Lake Michigan. Ocean waves are very different from Great Lake waves.
Water Safety – Winter Beach Hazards: Water safety is so important during the winter. When covered in snow and ice, it’s difficult to tell where the beach ends and the lake begins. Shelf ice is beautiful but dangerous. There are many places where it cannot support a person’s weight, which may cause a fall into freezing water below, so you should never walk on shelf ice.
Water Safety – How to Escape Dangerous Currents: Of the five Great Lakes, Lake Michigan has the highest number of drownings and rescues each year. Lake Michigan is freshwater. This is so different from an ocean. It doesn’t have the salt, so it is lacking that buoyancy already. If waves get super high and rip currents start to form and that water gets volatile, it is going to be much harder to get out of the situation if you start struggling while you are swimming.
Water Safety – Southern Lake Michigan: Lake Michigan has also had more than 250 recorded cases of swimmers caught in rip currents since 2002, which is double the combined total of the other four Great Lakes. Make sure you check the forecast before you come and have a safety plan. In the ocean you can get hit by two waves in 15 seconds but in the Great Lakes you could get his with five waves in that same time period. Learn more about high frequency waves and how dangerous it can be.
Illinois-Indiana Sea Grant combines research, education, and outreach to empower southern Lake Michigan communities to secure a healthy environment and economy. The program is funded through National Oceanic and Atmospheric Administration (NOAA) via the National Sea Grant College Program, as well as the University of Illinois and Purdue University. IISG also works in partnerships with key organizations, institutions, and agencies in the region to reach more audiences and multiply opportunities for success. IISG brings together scientists, educators, policy makers, community decision makers, outreach specialists, business leaders, and the general public to work towards a healthy environment and economy.

The Farmers Helping Hellbenders program is accepting applications for the second round of its Indiana Natural Resources Conservation Service’s Regional Conservation Partnership Program (RCPP) project. The project aims to assist with the conservation/recovery of eastern hellbender salamanders and improvement of aquatic resources in south central Indiana.
Eligible farmers and landowners, who wish to obtain funding to implement practices designed to keep nutrients and soil resources on fields and improve their watersheds, should contact their local NRCS office before May 10 to apply. Financial assistance is available for agricultural lands within the Blue River-Sinking Watershed boundary in Crawford, Floyd, Harrison and Washington counties, where the eastern hellbender can be found and is being actively managed.
Eligible practices for farmers in the project area include conservation cover, grassed waterways, wildlife habitat planting, nutrient management, riparian buffers and many others. Interested farmers and forest landowners who wish to implement conservation practices on their land should discuss their options with their district conservationist. Contact your local district conservationist by visiting Farmers.gov/Service-locator.
While NRCS accepts program applications year-round, Indiana producers and landowners should apply by May 10 to be considered for the current RCPP-Hellbender funding cycle. Applications received after May 10 will automatically be considered during the next funding cycle.
“The Farmers Helping Hellbenders RCPP project enables us to leverage partnerships to make a lasting positive impact on the habitat of the eastern hellbender salamander,” said Damarys Mortenson, state conservationist for the USDA’s NRCS in Indiana. “This project allows Indiana farmers and forestland owners to conserve the vital natural resources on their land while also protecting the habitat for hellbenders and other aquatic animals. It is a win-win.”
The eastern hellbender (Cryptobranchus alleganiensis) is a large, fully aquatic salamander, nicknamed the snot otter, water dog, devil dog, Allegheny alligator and water eel among other things. Their decline statewide has been documented as far back as the early-to-mid 1900s as a result of habitat loss and poor water quality. Hellbenders, which are listed as an endangered species in Indiana, play an important role in aquatic ecosystems and are indicators of clean water. Eastern hellbenders need clean water to survive as they breathe through their skin by absorbing oxygen from the river and stream water in which they live.
Hellbender populations are declining across their range, from Missouri to New York. This decline, which affects the hellbender population in Indiana’s Blue River, is likely caused by human influences such as habitat degradation and destruction. The stream-bottom habitat of hellbenders can be degraded by sediment from eroded banks and fields and destroyed when streams are dammed or dredged. Hellbenders are also captured inadvertently by anglers or purposefully for illegal sale in the pet trade. Finally, emerging diseases may be impacting some populations of hellbenders. Specifically, the chytrid fungus (Batrachochytrium dendrobatidis) and Ranavirus (family Iridoviridae) are considered to be major threats to the persistence of hellbender populations across their range.
For much of the last 17 years, Dr. Rod Williams and his team have been researching eastern hellbenders, spearheading regional conservation efforts and advancing hellbender captive propagation, or the rearing of this ancient animal in captivity and their eventual return to the wild. The partnership had a major breakthrough over the summer of 2023 with the documentation of a young hellbender salamander in the Blue River while conducting routine surveys. This discovery is significant because over the past three to four decades, only adult hellbenders have been documented in the Blue River. The presence of a young salamander suggests that conservation efforts and rearing programs are accomplishing their goals for the recovery of this endangered species.
The Farmers Helping Hellbenders RCPP project is made possible by $2.7 million in funding from the U.S. Department of Agriculture’s RCPP, Purdue and other partnering organizations. The project is led by Purdue with assistance from 14 collaborating public and private organizations on the state and local level including NRCS. The goal of the project is to improve hellbender habitat in a four-county region in south central Indiana by expanding the use of agricultural conservation practices that lead to decreased sediment in local river systems. The project aims to improve water quality, enhance aquatic habitat, increase aquatic wildlife populations, increase riparian and pollinator habitat and protect karst topography.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Spring is the time anglers return to fishing on Indiana’s lakes and rivers. Often that includes catching and using live bait. Remember to dispose of all unused bait fish properly in the trash, as invasive carp could be lurking in your bait bucket. Improperly disposing of unused bait fish in a lake or stream could potentially allow invasive species, like silver carp, to spread in Indiana waters.
Invasive carp are a select group of cyprinid fishes (minnow family) that are native to Asia. The term “invasive carp,” formerly known as “Asian carp,” collectively refers to bighead carp, silver carp, grass carp, and black carp. Each of these species was intentionally introduced into the United States for different purposes; however, all are now considered invasive nationally and in Indiana. Invasive carp compete with native species and pose a threat to Indiana’s aquatic ecosystems.
Find out more about how you can help in the fight against invasive carp at DNR: Fish & Wildlife Resources.
