''Callinectes ornatus'' is a species of swimming crab in the genus ''Callinectes''. It can be distinguished from the closely related Atlantic blue crab (''Callinectes sapidus'') by the presence of six frontal teeth on the carapace, compared with only four for ''C. sapidus''. ''C. ornatus'' is also smaller, at a maximum carapace width of only , compared to in ''C. sapidus'', and is therefore not commercially exploited.〔 Their shells are light yellow-brown to red-brown in color. The lower tips of the claws are blue. The two spikes on each side of their shells are not as long as in blue crabs. They can be found in the western Atlantic Ocean, as well the Caribbean coastlines. Their diet consists of small crustaceans and small fish. They are also scavengers. ==References==
