Octopuses hunt down anything that is vulnerable, killing their prey by injecting poison from their salivary glands. They have a short life span and only mingle once with others for copulation. These octopuses are huge in size only after a year of living. The dofleini come in various dark colors. They also have the ability to change colors and shape.
Females can only mate with mature males to produce offspring that are the size of a flea.
Octopus can regenerate any part of its body in six weeks when an amputation occurs, but becomes smaller than its original size. Many of these marvelous creatures have good eyesight, but can not see in color. Little is known about the abundance, distribution, and population trends of octopus. Octopus move by use of their mantles. The mantle cavity is used in breathing and locomotion.
