Data on life history and characters of Galeus piperatus, a dwarf shark of Golfo de California
MetadataVis full innførsel
Information is presented on a recently described dwarf shark, Galeus piperatus, which occurs through a wide range of depth in turbulent waters of highly varying physical parameters in Golfo de California, Mexico. It barely exceeds 300 mm in total length and an egg-case presumed to be of this species is only 35 mm long. Young about 80 mm long are well formed and very active. The sexes are remarkably alike in most respects but differ in tooth structure. The denticles of the young bear a single hooked spine, but are pedunculated tridents in the adult. The claspers are large, robust, and of highly complex external and internal structure.
