The muscular system of Octopi
Octopi have two eyes and four arms. They are most likely the smartest and
most flexible of all the invertebrate animals. They inhabit many parts of
the oceans, usually in coral reefs. There are around 300 species.
Octopi move around by crawling or swimming. Their main way to travel
slowly is crawling with some swimming. Jet propulsion is their fastest way
of movement. The inner skin of octopi is composed of many levels of
muscle. In octopi there are three different types of muscle: longitudinal,
circular and radial. Lacking skeletons octopi are composed of mostly fluid
muscle. The muscle is incompressible. The way octopi move is to
quickly extend the mantle and then contract it making a jet propulsion system.
Octopi' muscle fibers run in all directions and when contracted they
form a "skeletal support system." The muscle fibers create their own
skeletal system. Since they have no skeletal system octopi are extremely
flexible. In octopi' arms and tentacles there is something called muscular
hydrostat. It is a biological structure which is found in many animals.
It is used to move the host about and consists mainly of muscles. It
performs its hydraulic movement without fluid. The muscular system of
octopi acts as both as muscle and as a skeleton.
