About
Brownish to greyish swell shark with a broad dark saddle behind the eyes, and a dense array of irregular very dark spots, blotches and saddles, sometimes with paler flecks on the body. Small juveniles have small dark spots and faint saddle-like blotches, and larger juveniles have darker saddles only.When disturbed or threatened, swell sharks increase their size by inflating their stomachs with air or water in an attempt to avoid predation
