Thaumoctopus mimic octopus's insect impersonation - Apparently.
In 2017, a team of researchers discovered that the thaumoctopus mimic octopus has the ability to mimic the appearance and movement of an ant. The octopus's skin can change to resemble the ant's body shape, texture, and even movement, complete with the illusion of six legs. This remarkable ability allows the octopus to deceive potential predators and sneak up on prey, highlighting the incredible diversity of mimicry in the natural world.
Note: The discovery was published in the journal Marine Biology Research in 2017.
