Mantis shrimp (Squila empusa) get their name from their "praying mantis-like" appearance, although they are not true shrimp. They have claws that strike out with incredible speed and power, able to instantly chop small fish in half. These crustaceans are also known as thumb splitters among shrimp fishermen who must watch for these voracious predators in their nets. Mantis shrimp are nocturnal and are sometimes caught during night trawls in the Reserve. A living mantis shrimp can sometimes be seen an the acrylic (not glass) focus tank in the Environmental Learning Center exhibit hall.
