Hatching: ~3 mm Flexion: ~6 – 9 mm

-- Morphology: In preflexion larvae the body is deep with 29.5 % of the NL and deepens more with development to 37 % of SL in postflexion stage, but decreases again in juveniles of more than 20 mm to 32 % of SL. The gut is short with 36 % of NL and increases with development to 55 % of SL. Flexion takes place at 6 – 9 mm. All fin rays of caudal, anal, pectoral and pelvic fins are developed at a size of 13.2 mm. The second dorsal fin forms after the development of the first dorsal fin is completed. Since the studied specimen was in the late postflexion stage, all rays had already developed and species identification was done by meristic counts. There are no preopercular spines present.

-- Pigmentation: The pigmentation on the head and on the trunk is strongly developed. Already the late preflexion larvae lack the pigmentation series ventrally on the caudal peduncle, but a series of four to five spots occur on the caudal fin. During postflexion stage pigmentation spreads from the head dorsally backwards over the trunk. Dispersal of pigments also occurs on the caudal peduncle, where melanophores start to develop.

-- Reference: HAEDRICH (1986); OLIVAR and FURTAÑO (1991);

-- Reference material: 1 specimen; 03/02: S13 (P691561);

-- Distribution: A single specimen was found southeast of Fuerteventura at a depth of 632 – 1035 m in day during winter.

CAPROIDEI > Caproidae The body is very deep bodied and laterally highly compressed. An occipital crest is present and the eyes are large.The mouth is large and protractile. The dorsal spines are elongated and pectoral fin spines are present. The number of vertebrae is low.
