Taxonomy
Prionotus carolinus was first formally described in 1771 by the Swedish scientist Carl Linnaeus as Trigla carolina with the type locality give as "Carolina". The specific name refers to the type locality.
Description
Prionotus carolinus can be identified by its broad spiny head, tapering body, blue eyes, and large, wing-like pectoral fins. The dorsal surface is reddish or grayish, the chin black, the belly pale and the fins reddish-brown with darker edges and paling to grayish-white at their bases. Three lower rays of the northern sea robin's pelvic fins are feelers used to "walk" along the bottom, so as to stir up bottom sediments to find food. Northern searobins grow to an average of 17 inches (43 cm) long.
Distribution and habitat
Prionotus carolinus is found in shallow seas from is found in the western Atlantic where its range extends from Nova Scotia along the Atlantic coast of the United States into the Gulf of Mexico as far as the upper Florida Keys where they are found in estuaries to the edge of the continental shelf. They prefer the sandy bottoms of the waterbed, where they feed by kicking up sediment to find food, using their "legs".
Diet
Prionotus carolinus feeds on a wide variety of invertebrates, including shrimp, crabs, amphipods, squid, bivalve mollusks, and segmented worms. It has also been known to bite readily on any bait, suggesting a fairly non-selective feeding habit.
Uses
Prionotus carolinus are primarily fished for sport as they put up a good fight when hooked. The spines make it difficult to clean them but they have edible flesh that is comparable with Kingcroaker or whiting and can be broiled and baked.
Other uses for the northern sea robin are processing into fish meal, pet food or fertiliser. They are also used for baiting lobster pots and handlines for catching flatfish. Their eggs have been used as a substitute for caviar.
