Octopi Facts

5 Facts you didn´t knew about octopi

· It is a common mistake to refer to an octopus' arms as tentacles. Tentacles are longer than arms. Tentacles usually have suckers only at their tips.

· Most species of octopi can release a thick cloud of black ink that helps to confuse predators and provide the octopus an edge when attempting to escape. One of the pigments in the octopus' ink is melanin (the same pigment that gives our skin and hair color).

· Chromatophores enable an octopus to camouflage itself with its surroundings by changing the appearance of its epidermis.

· An octopus has three hearts.
Two hearts are used to pump blood to each of the octopus' lungs and the third pumps blood throughout the body.

· Octopi move through the water either by crawling or by jet propulsion.
Octopuses are among the few animals that move by means of jet propulsion. Because jet propulsion requires much energy, many octopuses also crawl when moving more slowly. 

Night dives at Phantom Divers are your best opportunity to watch them hunt for food or in constant movement!!!!
