Istiblennius steindachneri

Istiblennius steindachneri is a combtooth blenny found in the western Indian Ocean, inhabiting regions from Kenya to Mozambique, including areas around Madagascar, Mauritius, and the Seychelles. This species reaches a maximum size of 11 cm in standard length. Males can be distinguished by a spotted occipital crest and dark stripes on the caudal peduncle, while females lack the crest and have dark spots and pinstripes on the posterior part of their body. This blenny is a marine, demersal fish, often found in tropical coastal waters. It is known for its facultative air-breathing ability, allowing it to survive in various conditions. The species is oviparous, with distinct pairing during reproduction. Eggs are adhesive and attach to substrates via a filamentous pad, while larvae are planktonic. Divers encountering Istiblennius steindachneri are likely to find them in shallow, coastal habitats. The species is harmless to humans and currently holds a conservation status of Least Concern according to the IUCN Red List.
