How Ocean Animals Vanish_ Mimic Octopus, Leafy Sea Dragons, Whale Sharks

How do ocean animals vanish in plain sight? From mimic octopus impersonations to whale shark countershading, discover ingenious survival tricks creatures use to evade predators.

Life under the sea is a daily contest of hide and seek. Under The Sea reveals nature's smartest disguises, starting with cephalopods. Octopuses read the world with camera-like eyes, then fire thousands of chromatophores to match color and even raise skin to mimic texture. When chased, squid and cuttlefish blast off using siphons at up to 40 km/h and cloud the water with ink. A coconut octopus hugs a portable shelter, while the mimic octopus scares threats by acting like toxic neighbors such as lionfish and sea snakes. Even fish cheat: the edible mimic filefish copies the poisonous black-saddle toby to slip past predators.
