This creature is designed that it looks like a dead leaf or a creature wearing bright red lipstick that forgets how to swim.
The name batfish actually belongs to two entirely different families of marine fish. While they share a name, they have evolved completely, separately, and developed strategies to survive.
One family dominates the open waters of coral reefs by pretending to be foliage, while the other walks along the dark ocean floor looking like a grumpy sci-fi alien.
Let take a look at each of them

The Reef-Dwellers
Also called Spadefishes, it is found throughout the warm waters.These batfishes are vertically flattened, disc-shaped, and elegant. As adults, they are prominent features on tropical coral reefs.
the bottom-walkers
Also called Ogcocephalid Batfishes. This family belongs to the anglerfish order and lives primarily on the sea floor, sometimes thousands of feet down. They have flattened body , look like pancakes, and are famous for their terrible swimming skills.

The juvenile orbicular fish
If you ever go diving in the Indo-Pacific and see a dead brown leaf drifting aimlessly just above the sandy bottom, look closer. It might actually be a juvenile Orbicular Batfish .
To avoid being eaten by larger predators, young batfish have evolved a defense mechanism called mimicry.
Their bodies are deep, compressed, and colored in mottled shades of rusty brown and black.
Even the behavior
They float sideways and let the ocean currents push them around. To a passing predator, they look completely unbalanced ust another piece of floating mangrove debris
As they grow up, they shed this disguise. Adult reef batfishes lose their long, leaf-like fins, turn a sleek silver-grey with dark vertical bars, and become highly social, curious fish that frequently approach scuba divers.
They forgot how to swim
On the other side , is the Red-Lipped Batfish which has scientific name Ogcocephalus darwini. This is an endemic species found almost around the Galápagos Islands.
While the reef bat fish is good in mimicry, the red-lipped batfish is famous for its weird appearance. You Looking at it and you might wonder if it’s a fish at all.
They walk under water
The red-lipped batfish is poor, extremely poor swimmer. Over millions of years and evolution has passed by , its pelvic and pectoral fins have evolved into limb-like appendages. Instead of swimming through the water column. It uses these legs to clumsy-walk across the deep floor of the ocean in search of food.
But why the name red lips ?
The most striking feature of this fish is a brilliant, a bit permanent slash of crimson lipstick. While scientists are still studying the exact purpose of this bright coloration, the near leading reason is mate attraction.
In the deep ocean floor, those glowing red lips act as a visual map to help male and female batfish find one another.
They have a hidden Fishing Rod
Because they can’t chase down prey, they rely on a built-in fishing rod called an illicium. Located on their snout, this small extension secretes a chemical scent that lures in small crabs, mollusks, and shrimp. When the prey gets close enough to investigate, the batfish strikes with surprising speed.
