Horseshoe Crabs: An Ancient Species in the Modern World

Horseshoe Crabs: An Ancient Species in the Modern World

Watch this clip from MHTV, and read more about this program and register below to attend in person or via Zoom! 

Horseshoe crabs evolved almost 450 million years ago and are considered the “living fossils” of our time, surviving ice ages, asteroids, and five mass extinctions. Today, they continue to serve an important role, both ecologically and economically, as their eggs provide sustenance for endangered shorebirds and their blue blood is used to advance biomedical research. Though they’ve endured these catastrophic events throughout Earth’s history, their population is in decline. Alison will discuss the importance of this elusive, prehistoric creature and how we can help it survive the next mass extinction. 

Registration is required to attend in person or via Zoom.
