VIMS Articles
A new species of deep-sea ophidiid, Porogadus situs, is described from deep water off the Bahamas, It differs from its congeners chiefly in having a relatively shorter and deeper head, absence of preopercular and frontal spines and relatively large scales covering the body. A partial osteological description of P. situs is given. porogadus is reviewed and a provisional key to species from the western North Atlantic is presented. The species group containing Porogadus that lack well developed head spines and armature is partially revised on the basis of a study of specimens collected from the Atlantic and Pacific oceans. Of …

Elongate dorsal appendages adorn pelagic larvae of many fishes from disparate taxa, among them larvae of the family Carapidae, wherein the singular, elongate appendage is termed a vexillum, The vexillum is a complex larval specialization of the dorsal fin and is characteristic of all carapid genera, It is motile, well vascularized, and innervated by a branch of a cranial nerve with no apparent spinal innervation. Histological studies of Echiodon dawsoni and Carapus bermudensis vexilla show a two layered epidermis with mucous cells, an arteriole and venuole, two myelinated peripheral nerve fascicles, and two collagenous central shafts. No taste buds, free …
