The Hairy frogfish (Antennarius striatus), also known as striated frogfish and striped anglerfish, can grow up to 25 cm in length with a round, expandable body, covered with small skin extensions which resemble hairs and aid camouflage among corals, sponges and sea weed. Individual frogfish may be yellow, beige, or brownish with zebra-like striping. But there are also white, orange, green, bluish, gray, and black relative to its immediate surroundings. Hairy frogfish are quite rare and always yellow-brownish. The unusual appearance of the frogfish is designed to conceal it from predators and sometimes to mimic a potential meal to its prey. Their camouflage can be so perfect, that sea slugs have been known to crawl over the fish without recognizing them.
These frogfish are found in the Indo-Pacific Ocean and Red Sea coast, the Hawaiian Islands, Japan, Australia and New Zealand. In the Americas they ae distributed from New Jersey to Brazil, including the Gulf of Mexico and Caribbean Sea.
Males are much smaller than females but have stronger coloration and more dermal extensions on the body.
