🐟 Batfishes (Family Ogcocephalidae) Batfishes are a distinctive group of bottom-dwelling anglerfishes known for their strange, flattened bodies and unusual method of “walking” on the seafloor. They belong to the order Lophiiformes, the same group as deep-sea anglerfish.

🔹 Key Characteristics

• Body Shape: dorsoventrally flattened; triangular, disc-like form

• Locomotion: walk on modified pectoral and pelvic fins like limbs, rather than swimming

• Mouth: small, often slightly turned downward

• Skin: rough, often covered with mucus-secreting tubercles

• Illicium (fishing lure): a small lure in front of head, sometimes retractable and reduced

🔹 Size

• Typically 10–40 cm in length (a few species larger)

🔹 Habitat

• Tropical and subtropical oceans worldwide

• Found on continental shelves and slopes, coral reefs, sandy and muddy bottoms

• Depth range: shallow coastal waters to >1000 m deep (many species deep-sea)

🔹 Behavior & Diet

• Poor swimmers — rely on camouflage and walking

• Ambush predators

• Feed on small fish, worms, crustaceans using the illicium to attract prey

🌊 Special Adaptations

Adaptation	Purpose
Modified fins like legs	Walking on seabed
Cryptic coloration	Camouflage on sand/mud
Reduced illicium	Still acts as lure but less prominent than other anglerfish
Flattened body	Bottom-hugging lifestyle

Some species also have structures that help detect chemicals on the seafloor — useful for hunting in murky depths.

📌 Interesting Facts

• Their faces and body shapes often appear bizarre — sometimes compared to frogs, rays, or even UFOs!

• Some species can inflate themselves slightly when disturbed.

• Their mucus-coated skin may help prevent infections.
