Species Overview

Great Hammerhead Shark

The great hammerhead is the largest of the nine hammerhead shark species. Its distinctive cephalofoil (hammer-shaped head) houses an array of electroreceptors that allow it to detect stingrays buried beneath the sand.

Northern Snakehead

The northern snakehead is an aggressive freshwater predator native to East Asia. It can breathe air and survive out of water for several days. Considered a destructive invasive species in North America, it provides exciting catch opportunities.
