(Shortnose chimaeras or ratfishes)
Etymology: Chimaera: Latin, chimaera = marine monster, 1634 (Ref. 45335). More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range
; 海 深海魚; 海洋回遊性 (Ref. 51243); 深さの範囲 40 - 1400 m (Ref. 104125), usually 300 - 500 m (Ref. 4443). Deep-water; 75°N - 27°N, 32°W - 35°E
Eastern Atlantic: northern Norway and Iceland, Skagerrak and Kattegat south to Morocco including western Mediterranean (some isolated records from eastern part), Azores and Madeira Islands. Records from South Africa are questionable. Reported from Oshima, Japan (FMNH 89161) (Ref. 27954).

Max length : 150 cm TL オス/雌雄の選別がない; (Ref. 35388); 最大公表体重: 2.5 kg (Ref. 4645)
Bathydemersal to benthopelagic generally between 300 and 500 m depth. Found in the upper continental slope. Usually found in deeper waters in southern latitudes, while making a summer inshore migration up to 40-100 m in the northern areas. Sluggish, usually occurring in small groups. Feeds mainly on bottom-living invertebrates. The single dorsal spine is sharp and pointed, and although only mildly venomous can inflict a painful wound. Oviparous. Males have a clasper on the forehead that is probably used to hold on to the female during copulation. Egg capsules are about 17 cm long; young look alike adults and hatch when 10 cm long. Common by-catch when trawling for shrimps in the North Sea or Skaggerak.

Oviparous; egg-capsules slender, club-shaped with narrow lateral membranes and a horny filament at the long pointed end, 17 cm long and 3 cm wide; deposited mainly in spring and summer. The embryos developing in about 9-12 months and hatch at 10 cm length.
