Leopard Rockskipper

Blenniella leopardus

The Leopard Rockskipper, Blenniella leopardus, is a small reef fish found in the eastern Indian Ocean, ranging from Sumatra to the Andaman Islands. It inhabits shallow waters, typically within a depth range of 0 to 2 meters, often seen in the intertidal zone. This species prefers the inner portions of reef flats, where it can be found in small, irregular sand pools among limestone outcrops and coral fragments. Identifying the Leopard Rockskipper involves noting its elongated body and distinct fin structure. Males can grow up to 6 cm in length, while females reach about 5 cm. The dorsal fin is characterized by 12 to 14 spines and 17 to 20 soft rays, while the anal fin has 2 spines and 19 to 22 soft rays. Males display dark brown saddles along their backs with blue dashes midlaterally, whereas females have dark vertical H-shaped bars and numerous spots on their dorsal and caudal fins. Leopard Rockskippers are oviparous, with eggs that are demersal and adhesive, attaching to substrates via a filamentous pad. The larvae are planktonic, often found in shallow coastal waters. As a species, it is classified as Least Concern by the IUCN. Divers encountering this fish may observe its unique behavior and markings in its natural habitat.
