Omobranchus obliquus, the roundhead blenny or the mangrove blenny, is a species of combtooth blenny found in coral reefs in the Pacific and Indian oceans.[2] It grows to 5 to 10 cm (2.0 to 3.9 in) in length.[3][4]
Habitat
[edit]This species can be found in coral reels in both Indian and Pacific oceans,[2] but it is also spotted in areas of Philippines Islands, Guam, New Guinea, Samoa Islands and many more.[5] It is also lives in tidal pools, rocky shores,[4] edges of mangrove swamps, and muddy to sandy bottoms of algae and eel grass.[6] However, it is an invasive species found at Kaneohe, Oahu at places with fouling habitat that are sheltered.[7] Often, this species is spotted 2 m (6.6 ft) deep in salty or seawater,[6] and never seen at depths over 4 m (13 ft).[8]
Behavior
[edit]Despite this species being found in many different territories, it often prefers living in small groups or in isolation,[6] but they are considered to be juveniles.[clarification needed][8] Like other blenniids, it is a protector and home builder.[8] Due to its rounded head, long body with brown/greenish and yellow hues, it easily blends in with its surroundings. It also has excellent vision due to its bulbous eyes.[4]
