Prionotus carolinus
Size:
to 16"
Description:
Sea Robins are distinguished by the three free rays of the pectoral fins, with which the fish can actually walk across the bottom. They make frog-like croaking sounds when disturbed. Sea Robins have razor-sharp gill covers and spines, and are best left alone - there's not much meat on them anyway.
Sea Robins are generally found inshore in harbors and inlets, in 30-40 foot depths, but move out to deep waters in winter.
Prionace glauca
Size:
to 11 ft,
reportedly to 21ft
Habitat:
open ocean
Notes:
dangerous
A fast-swimming oceanic shark, these are colored vivid blue in life, but quickly fade to gray in death. The Blue shark is described as a persistent and dangerous stalker and is often found in great numbers. This is the shark most likely seen in caged shark dives off Rhode Island and is probably the commonest shark in our offshore waters during the summer months. Other identifying features of the Blue shark are the extremely long pectoral fins and relatively slim body ( compared to those below ) with very unequal upper and lower tail lobes.
