Description: A drawing of this species which is characterised by its conspicuous thorns, its description, habits and range.
Figure 31.—Thorny skate ( The thorny skate can be identified at a glance among skates of the Gulf of Maine by the fact that the row of thorns with which the midline of back and tail is armed are not only large and conspicuous, but do not number more than 19 at most from the nape back along the tail. There are also 2 or 3 large thorns on each shoulder; and one in front of each eye and one behind it; one close to the inner end of each spiracle; and other smaller thorns scattered on snout, pectoral fins, and tail. The bases of the thorns on the pectorals are star-shaped, a very distinctive character; those of the still larger thorns along the midline of the back are oval. Adult males have 2 rows of hooked, erectile thorns near the outer corners of the pectorals.
