OCTOPUS
What is octopus?
                Octopus is a sea animal that comes from Cephalopoda class. Generally it is bilaterally symmetric, it means if it is pulled out and divided by two, it’s symmetrical same. Octopus was discovered in 988 BC. For the complete informations :

Octopus Protection
 Ink
                When octopus felt harmed / felt something dangerous, such as predators, sharks, human or something else, it injects it’s ink to blured it’s enemy sight, so octopus can escape safely.
Poison
                When Octopus felt harmed / something dangerous, it sprays toxic to it's enemy.

Octopus’s Camouflage
1.       Under the sand
When octopus feel something weird and seems dangerous, it hides under the sand.
2.       Rock
Same like under the sand, but it hides behind or ‘hug’ the rock, so the octopus is safe.

Octopuses swim 8 hours per day. Octopus usually reproduces 200.000 eggs, but the eggs that alive, like around 30%. Also not all octopuses use ink, some of them use their poison to defeat their foe. The most popular poison is Blue Ring Octopus. Fact says that 20ml of it’s poison can kill 30 mouses or around 5 humans.
