Hallo Agan ... talking about squid, cuttlefish and octopus, Octopus is known the most intelligent invertebrates in between. They are also known as squid. With eight tentacles and two eyes, they are called the most living creatures of the sea. Using eight tentacles, the octopus can move and capture its prey.
The octopus is a mollusk animal of the Cephalopoda class (animal's legs located in the head), the Octopoda order with coral reefs in the ocean as the primary habitat. The octopus consists of 289 species that account for one-third of the total species of the Cephalopoda class. Octopus (Greek: Ὀκτάπους, eight feet) octopus often refers only to animals of the Octopus genus.
The Octopus Facts
Octopus prefers to make coral reefs as their primary residence. They have no bones but they have soft tissue around all parts of their body. The only difficult part of their body is the beak, which is positioned between their eight tentacles. This hard beak is shaped like a parrot's beak.
Octopus can see and hear sounds they can not hear. Fact
another that may amaze Agan about the octopus is that it turns out the octopus has three hearts. Octopus Using two hearts to drain blood through the gills, while one heart is used to distribute heart blood throughout the body. Octopus has a physical structure nearly 4.3 feet long and 220 lbs in weight.
There are more than 200 species of octopus found in waters all over the world. The largest species can grow up to 16 feet long. They are mostly located in the ocean. Species found in cold water are relatively larger compared to those living in warm water. Although they are known to live in the oceans, Agan may find them only in the ocean section that has many coral reefs and rocky environments for them. They can be found alive in cracks made in stone. They find the hole or gap is quite protected.
They like to eat what they see around them including crayfish, shellfish, crabs, mollusks, etc. While the octopus is eating, the octopus holds its prey with its tentacles. They use their venomous saliva to inject into the body of their prey. It makes weak prey and then they start sucking prey meat using their hard beak.
Octopuses generally hunt at night and spray black ink to confuse prey. Black ink is also used as a protector to get away from predators. By spreading ink, they can hide behind rock gaps and get rid of predators. This ink is so dense that it can blind predators. Lack of bones also allows them to bend faster under coral reefs. Moray, Congers, sharks and eels are some of the major threats to octopus to realize.
They also have a unique feature of mixing with their environment. It also helps them to get away from reaching from predators. In any case, if their tentacles are injured or cut, this will not cripple the octopus because their tentacles will gradually grow again.
