Etymology: Halosaurus: Greek, als, alis = salt + Greek, sauros = lizard (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marinhas batidemersal; intervalo de profundidade 440 - 1700 m (Ref. 4448). Deep-water; 38°N - 35°S, 98°W - 20°E
Eastern Atlantic: Azores and Morocco to South Africa, including western Mediterranean (off Algeria). Western Atlantic: Gulf of Mexico, Caribbean, and off Lesser Antilles.
Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL macho/indeterminado; (Ref. 4448)
Espinhos dorsais (total) : 1; Raios dorsais moles (total) : 8 - 9. Body is compressed (Ref. 37108). Pinkish with silvery reflections, darker dorsally (Ref. 3974). Lacks the checkerboard pattern of whitish and brown, produced by concentration of pigment at the margins of the scale pockets (Ref. 37108).
