Etymology: Bassozetus: Latin, bassus = thick, fat + Greek, ketos = marine mosnter, whale (Ref. 45335).
Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
marino batidemersal; rango de profundidad 3965 - 5200 m (Ref. 84269). Deep-water
Atlantic, Indian and Pacific: restricted to abyssal depths globally..
Tamaño / Peso / Edad
Madurez: Lm ?  range ? - ? cm
Max length : 80.5 cm SL macho / no sexado; (Ref. 84269)
Radios blandos dorsales (total) : 114; Radios blandos anales: 93; Vértebra: 65. Snout inflated; eyes much smaller than snout; opercular spine weak or absent; preopercle without spines and posteriorly expanded almost reaching posterior margin of opercle; pseudobranchial filaments 2 (Ref. 34024).
Specimens were apparently caught on or near the bottom at abyssal depths (Ref. 84269). Rare species (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
