The wealth of the sea.
In the sea there are various types of animals other than fish, among others, namely Octopus....
The octopus has eight arms with a vacuum in the form of concave spheres on the arm used to move on the seabed and catch prey.
The octopus arm is a muscular hydrostatic structure that is almost entirely composed of a boneless muscle layer or outer skeleton. Most octopuses have a body consisting of muscle and boneless internal skeletons.
The octopus has no shell as a protector on the outside and does not have an inner shell or bone like squid. The beak is the hardest part of the octopus body used as the jaw to kill the prey and bite it into small parts.
