In August 2020, a long-nosed chimaera was brought up from 460 fathoms (2,760 ft; 840 m) off the Grand Banks of Newfoundland. [5] They range from 60 to 140 cm (2.0 to 4.6 ft) in maximum total length, depending on species. Rhinochimaeridae in the Gulf of Mexico at roughly 4,300 ft (1,300 m) deep
Rhinochimaera pacifica, commonly known as the Pacific spookfish, knifenose chimaera, narrownose chimaera, Pacific long-nosed chimaera, or Pinocchiofish, is a species of chimaera in the family Rhinochimaeridae. [2] It lives in various parts of the Pacific Ocean and can be characterized by its long snout.

Chimaera reproduction resembles that of sharks in some ways: males employ claspers for internal fertilization of females and females lay eggs within spindle-shaped, leathery egg cases. [1] Unlike sharks, male chimaeras have retractable sexual appendages (known as tentacula) to assist mating.
A Chimaeridae fish and deepwater mussels at edge of a brine pool.. The Chimaeridae, or short-nosed chimaeras, are a family of cartilaginous fish.. They resemble other chimaeras in general form and habits, but have short, rounded snouts, without the modifications found in related families.
The chimaera is a marine species, typically found on slanted and flat areas of deep oceans at the continental slope, sometimes extending into the bathyal zone. It has a broad depth range, occurring in waters 400 metres (1,300 ft) – 1,800 metres (5,900 ft) in depth, typically in the deeper part of this range. [5]
Chimaera carophila diets primarily consist of benthic-dwelling invertebrates but are also suspected to be detritivorous. One study found benthic invertebrates including gastropods , [3] barnacles, and polychaetes in the stomachs of two specimens. In the same study, they found other fish, cephalopods, and crustaceans in only one of the specimens.
Several fossil species are attributed to Chimaera, but only two are confidently assignable to it.These two are C. seymourensis from the Late-Eocene La Meseta Formation on Seymour Island off the coast of the Antarctic Peninsula, [6] [7] and C. pliocenica from the Pliocene of Tuscany, Italy. [7]
