Zigzag Pygmygoby

Trimma maiandros

The Zigzag Pygmygoby is a small reef-associated fish found in the Indo-Pacific region, including areas from the Cocos (Keeling) Islands to Japan, and as far as Samoa and Australia. It typically inhabits depths ranging from 1 to 55 meters. This species is easily recognizable by its zigzag pattern of irregular brown bars across its body, which provide effective camouflage among the reefs. The fish has a compressed, fusiform body shape and reaches a maximum length of 2.7 cm. Its unique morphology includes reduced predorsal scales and a distinct dark brown spot or bar extending from the eye. This goby is often found in mid to outer barrier reefs and is more commonly seen on outer barrier islands. It also frequents caves and crevices, utilizing these structures for shelter and protection. The Zigzag Pygmygoby is harmless to humans and is not of interest to fisheries. Its conservation status is categorized as Least Concern. Divers encountering this species can expect to find it in the crevices and caves of coral reefs, where it exhibits cryptic behavior, blending into the surroundings.
