Antennarius striatus, commonly known as the striated frogfish, is a master of disguise found in tropical and subtropical waters. It features a robust, globular body covered in fleshy appendages and distinctive stripes, aiding in camouflage among seaweed and coral. This ambush predator uses a specialized lure to attract prey.

Antennarius striatus, commonly known as the striated frogfish, is found in tropical and subtropical waters across the globe. Its geographical distribution includes the Atlantic Ocean, the western and eastern Indian Ocean, and the western Pacific Ocean. Specific regions where the species is naturally found include the eastern coast of the United States, the Caribbean, the Gulf of Mexico, the coast of Brazil, the Indian Ocean near Madagascar, and the Indo-Pacific region including the Red Sea and the Great Barrier Reef in Australia.

The striated frogfish typically inhabits warm, tropical waters, often found in coral reefs, rocky and sandy substrates, seagrass beds, and among floating seaweed. The species prefers shallow waters but can be found at depths ranging from 1 to 210 meters. The water temperature in these areas usually ranges from 24°C to 28°C.

Antennarius striatus is a benthic species, meaning it lives on the ocean floor. It is a highly specialized predator, using its unique appearance and behavior to blend in with its surroundings and ambush prey. The frogfish utilizes a modified dorsal fin spine as a lure to attract small fish and invertebrates, demonstrating an ecological adaptation for hunting in its habitat. The species often exhibits cryptic coloration and mimicry, resembling sponges or algae to evade predators and surprise prey.
