Also known as The harlequin mantis shrimp or The painted mantis shrimp and one of approximately 400 species of mantis shrimp and can be found in the Indo-Pacific from Guam to East Africa.
The Peacock mantis shrimp is one of the largest and most colorful mantis shrimp and is between 3 – 18 cm.
They are usually green in color with orange legs and leopard-like spots on the front shield.
They construct U-shaped holes in the ground near the coral reefs from 3-40 m.
The Mantis shrimp are an active hunter and prefer crustaceans, snails and mussels.
It has club-like claws that it uses to crush its prey, and the impact force can achieve
over 80 km / h or like a 22 caliber bullet. Because they strike so rapidly, they generate cavitation bubbles between the appendage and the striking surface. The collapse of these cavitation bubbles produces measurable forces on their prey in addition to the instantaneous forces of 1,500 newtons that are caused by the impact of the appendage against the striking surface, which means that the prey is hit twice by a single strike first by the claw and then by the collapsing cavitation bubbles that immediately follow. Even if the initial strike misses the prey the resulting shock wave can be enough to kill or stun the prey.
They have very good color vision and have the ability to see circularly polarized light. They are considered to have the most complex eyes in the animal kingdom and the eyes are mounted on stalks and can move independently of each other.
They are the only known animals with hyperspectral vision, meaning they can perceive light from infrared through to ultraviolet wavelengths.
It researched in their eyes and speculated be applied to a new optical media that performs better than the current generation blu-ray.
