The term mimic refers to imitate or impersonate of voice and action of others. Thaumoctopus mimicus, is an octopus that mimics other marine organisms. The distribution is restricted to Indo-Malay archipelago; it was first explored at off coast of Sulawesi in Indonesia on 1998. The average size of Mimic Octopus is 60 cm and their arms can extend up to 25 cm. Mimic Octopus is characterized by brown color with white strips. Like other octopus it has 8 arms with 2 rows of suckers and a mantle containing 3 hearts. The suckers have touch sensors and chemo receptors, that helps them to sense and taste the food before eating.  These creatures prefer muddy bottom in the sea and moves over bottom by jet propulsion using siphon. It is the only known marine species that can impersonate several animals. Since, the body of octopi are made of nutritionally fleshy muscle; devoid of spines it makes them the most susceptible prey for predators such as sharks, damsels and barracuda. They mimic the marine animals basically for two reasons first, to escape from its predator and secondly to catch its prey by mimicking as a mate of its prey organism example, it mimics as mate of crab.  
Behaviour
These intelligent creatures can mimic like the following marine animals
Lion fish:Spreading its arms wide and keeping the head in horizontal position, imitates a poisonous lion fish.

 Flat fish: Pulling its all arm backward and moving forward imitates a poisonous striped flat fish.

Sting ray: Moving forward by Pulling its all arm backward with one arm left behind impersonates sting ray with its deadly tail.
 Sea snakes: burrowing in sediment by leaving 2 arms outside the sediment bottom mimics banded sea snake.
 Jelly fish: It puffs its head and siphon to imitate deadly jelly fish, then it moves to the surface and sinks down like jelly fish.
