Clown Blenny

Ecsenius axelrodi

Ecsenius axelrodi, commonly known as the Clown Blenny, is a small reef-associated fish found in the western central Pacific Ocean, particularly around the Admiralty Islands, Papua New Guinea, and the Solomon Islands. This species typically inhabits coral reefs, preferring the outer reef crests and slopes where it can be found at depths ranging from 3 to 36 meters. The Clown Blenny is characterized by its elongated body, reaching a maximum length of 5.8 cm. It displays a variety of color patterns, often featuring broad orange bands along the body and transverse black bars on the rear half. A distinguishing feature is the obliquely-sloping, oblong black spot above the pectoral fin and several round black spots near the dorsal fin. The Clown Blenny is known to be solitary or form small groups on coral outcrops. It thrives in clear waters with rich coral habitats, living on rocks and corals on steep slopes. Reproduction involves oviparous behavior, with females laying adhesive eggs that attach to substrates. The larvae are planktonic, developing in shallow coastal waters before settling into their reef habitats. For divers encountering the Clown Blenny, it is harmless and can be observed perching on corals or rocks. The species is currently assessed as Least Concern by the IUCN.
