Pholidoteuthis adamiMichael Vecchione and Richard E. Young
This is a large, moderately muscled squid that reaches a ML of 78 cm., and is thought to be very abundant in the upper Gulf of Mexico (Voss, 1956) and common off the east coast of the United States to New England (MV, pers. observations). One squid was seen from a submersible hovering just above the bottom on the continental slope off North Carolina (east coast, U.S.A.) (see Distribution).

Basal arm suckers have pointed teeth on the distal half of inner ring, while suckers from mid-arm have teeth all around the margin of the inner ring, although the teeth are larger distally.
Leta (1987) described Pholidoteuthis uruguayensis from off Uruguay. Nesis and Nikitina (1990) synonymized this with P. adami.
The type locality is the Gulf of Mexico, 29°12'N, 88°08'W.
The distribution is confined to the Western Atlantic from off New England to the Gulf of Mexico and to Uruguay. Large individuals are generally caught in bottom trawls in the bathyal region and are, therefore, thought to be bottom associated.
