The Hairy frogfish (Antennarius striatus) are found in the Indo-Pacific Ocean and Red Sea coast, the Hawaiian Islands, Japan, Australia, and New Zealand. In America, they are distributed from New Jersey to Brazil, including the Gulf of Mexico and the Caribbean Sea.
The Hairy frogfish, 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 seaweed.
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 frogfish’s unusual appearance is designed to conceal it from predators and sometimes to mimic a potential meal to its prey. Their camouflage can be so good that sea slugs have been known to crawl over the fish without recognizing them.
Males are much smaller than females but have stronger coloration and more dermal extensions on the body.
