Summary
| Description |
Arenaeus cribrarius (Lamarck, 1818) - dorsal view of a speckled crab carapace in Florida, USA. (December 2012) Orientation: anterior at top; posterior below. The crustaceans are a large group of arthropods that inhabit marine, marginal marine, freshwater, and terrestrial habitats. The crustaceans include crabs, lobsters, shrimp, crayfish, barnacles, ostracods, and other organisms. The oldest fossil crustaceans are in the Cambrian. The group experienced a significant radiation in the oceans during the Mesozoic Marine Revolution. The above photo shows a carapace of a speckled crab, Arenaeus cribrarius. This species is a swimming crab with a carapace morphology similar to that of blue crabs (Callinectes sapidus - see: www.flickr.com/photos/jsjgeology/23886163513). Speckled crabs are frequently infaunal - they bury themselves in shallow-water and beachface sandy sediments. Arenaeus cribrarius preys on molluscs, decapods, and fish.
