Mackerel Scad

Mackerel Scad

Decapterus macarellus

Size: to 12"

Habitat: coastal waters

Notes: Scads are diminutive Jacks. Late in the season huge schools of 3-4" babies may be found in the rivers and swarming around the inshore reefs. Note the detached rays on the dorsal and anal fins near the tail, forming a finlet like a mackerel. They are mainly harvested for bait but are also sometimes eaten dried or salted.

Blue Shark

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.
