Imspringer

Istiblennius bellus

The imspringer, also known as the rockskipper or dusky blenny, is a species of combtooth blenny found in coral reefs across the Pacific and western Indian Ocean. Males can grow up to 16 cm, while females reach a maximum size of 13.1 cm. Males are distinguished by several paired bands and spots from the mouth to nape, with dusky stripes on the dorsal fin. Females display dusky bands and fine dark specks covering their body, head, and fins, except for the pelvic fins. This species inhabits shallow waters, typically found in intertidal flats and rocky shores, with a depth range of 0 to 3 meters. It is distributed from the western Indian Ocean, including locations like Somalia and South Africa, to various Pacific islands such as Samoa and Niue. The imspringer is a facultative air-breather and exhibits oviparous reproduction, with eggs that are demersal and adhesive. Divers may encounter the imspringer on reef flats, where it exhibits territorial behavior. It is harmless to humans and currently holds a conservation status of Least Concern according to the IUCN Red List.
