The fish become mature when about 35 mm (1.4 in) in length. The male has modified anal fin rays, and either they are used as claspers with fertilisation being internal, or the male clasps the female and fertilises the eggs as they are being laid. Small clusters of eggs are laid in late

The tidepool sculpin grows to a length of about 8 cm (3 in) and has a large head, tapering body, and spiny fins. It has a single pre-opercular spine and tufts of cirri on the top of the head but not on the body below the dorsal fin as the
