News
Big claws, big costs: Trade-offs in crayfish signaling
A new study by researchers at The University of Queensland found that while freshwater crayfish have powerful claws, their large size slows swimming and drains energy. These appendages come with a trade-off between strength and mobility.
UW-Stevens Point students teach school children about invasive species
Waupaca County students participated in Conservation Field Day at Hartman Creek State Park, hosted by Golden Sands Resource Conservation & Development Council. Guided by University of Wisconsin-Stevens Point students, they explored invasive species and used nets to capture rusty crayfish and other aquatic critters.
The Great Lakes: Protecting Our Natural Wonder from pollution, climate change, invasive species
Chicago scientists warn that invasive species are threatening the Great Lakes, with rusty crayfish displacing native species and red swamp crayfish spreading in local waterways. These invaders disrupt habitats and may carry microplastics up the food chain, impacting wildlife and human health.
Chagrin River’s strangely colored rusty crayfish
Dr. Sean Williams, professor at Cuyahoga Community College, found an unusually colored rusty crayfish in the Chagrin River. Though common in Ohio, this one stood out with a very rare bilateral coloration.
This selection of invasive crayfish information is collected by the Invasive Crayfish Collaborative, a program convened and facilitated by Illinois-Indiana Sea Grant and the Illinois Natural History Survey with funding from the Great Lakes Restoration Initiative.
