The abyssal fish Antimora rostrata (Günther)

Abstract 1. 1. Antimora rostrata is a wide-ranging codlike fish (family Moridae) inhabiting abyssal depths throughout most of the worlds oceans. It is abundant in certain areas but supports no commercial fisheries. 2. 2. Little is known of its life history although it can be assumed that A. rostrata is benthopelagic in habit, feeding on free-living macrofauna that live on or just above bottom. It may also root in the bottom by using its spadelike snout. 3. 3. There is evidence that the fish forms aggregations segregated at larger sizes by sex. Females predominate in catches; large males are uncommon.

A NEW GRENADIER, GENUS CAELORINCHUS, FROM AUSTRALIA AND NEW ZEALAND (PISCES, GADIFORMES, MACROURIDAE)

Abstract A new species, Caelorinchus trachycarus, is described from continental slope depths of 622–1350 m off New Zealand, southern Australia, and the Norfolk Ridge south of New Caledonia. The modified scales of head ridges is especially spiny, more so than in any other member of the genus. The blackish fins, dark overall coloration, prominent free neuromasts on the head, and the numerous parallel rows of spinules on body scales distinguish the new species from the closely similar and sympatric C. acanthiger. It differs from C. parallelus and C. kermadecus by its naked nasal fossa, snout length, and scale spinulation, among other characters.
