Aquatic Invertebrates - invasive

European Green Crab (Carcinus maenas) on Nov 10, 2025

Submitter has sample

Description of specimen

We caught 7 small green crabs today and lost another 4-5 tiny ones through our traps holes. I saw another 5 caught today including a rather large one (5 inch diameter carapace roughly). Very hardy and feisty. Definitely harder to kill. They aren’t docile while flipped and they seem to last out of water for a long time.
