Small banded rattail (Coelorinchus parvifasciatus) fish species information

Scientific Name
Coelorinchus parvifasciatus

Common Name
Small banded rattail

Biology
Dorsal spines (total): 2. Several faint dark dorsal saddle marks on the posterior half of the body; pale intervening marks about the width of two scale rows; naked ventral surface of head and lower jaw (some with 1-3 scales beside articulation of lower jaw); dorsal anterior snout with naked triangular areas; naked below nostrils to suborbital ridge; large well-developed oval dermal window of light organ separated from anus by 2-3 rows of scales; lateral and medial processes of nasal bone not continuous (Ref. 26363). Resembles Caelorinchus maurofasciatus, C. mystax, C. bollonsi, C. cookianus, and C. fasciatus. Differs from C. mystax, C. bollonsi, and C. fasciatus in numbers of pyloric caeca (22-28 versus 111-115, 27-38, 12-23, respectively) in addition to other characters (Ref. 26363). C. parvifasciatus has similar numbers of pyloric caeca to C. maurofasciatus and C. cookianus but differs in having saddle markings only on the posterior half of the body (Ref. 26363).
