Warty Frogfish

Antennariidae maculatus

The warty frogfish is a member of the anglerfish family and are found in the tropical waters of the Indo-Pacific. They typically walk instead of swim on modified fins and their bumpy skin helps them blend in with their surroundings. They use a modified fin as a lure to attract their prey and can rapidly expand their mouth to swallow prey as big as themselves!
