Quick Definition
The resemblance of one organism to another species or object, conferring an adaptive advantage such as protection from predators or access to prey.
📖 Full Definition
Mimicry in fish encompasses several categories. Batesian mimicry: a harmless species resembles a dangerous or unpalatable species (e.g., the mimic filefish resembles a toxic pufferfish). Aggressive mimicry: a predator resembles something harmless to gain access to prey (e.g., the blenny Aspidontus taeniatus mimics the cleaner wrasse Labroides dimidiatus, approaching unsuspecting fish to bite off scales). Müllerian mimicry: two harmful species converge on a common warning pattern. Visual mimicry may also involve behaviour, colour patterns, or body shape.
💡 Examples & Context
The mimic octopus (Thaumoctopus mimicus) can impersonate over a dozen different species including flatfishes, lionfishes, and sea snakes.
