Blue-ringed Octopus

This is One of TheBeautiful Blue-Ringed Octopuse.

Blue-ringed octopuses are among the deadliest animals in the sea. I believe that everybody might think that this tiny creature is beautiful because of the color on their skin, but this tiny creature is so deadly among the other octopuses. 

Pbs.org - have mentioned that “the blue-ringed octopus appears grey or beige with light brown patches when it is at rest, but when agitated its 50 or 60 bright blue rings appear and pulsate with color, as a warning.” The Blue-ringed octopuses feed on small crabs, hermit crabs, and shrimp that it hunts during the day. It have two types of venom secreted by two separate venom glands are used against prey and predators. One of the venoms is used for hunting crab, the other, which is extremely toxic, is used as self defense against predators. Based on Marine Bio.com - Blue-ringed octopuses can be found only in the temperate waters of southern Australia, from southern Western Australia to eastern Victoria at depths ranging from 0-50 meter.
