Among all living organisms that live in our planet, the species that have captivated human attention are the sea creatures. Of all these sea creatures Octopus is definitely distinct from other variety of organisms. I have always wondered and admired the characteristics of Octopus. From the name itself it is self explanatory that the Octopus is a eight legged which are referred to as arms. It is more rightfully called as Devil Fish. It lacks skeletal structure unlike other fish species. They have suction cups on their arms and are also used to sense taste. Imagine the extraordinary power of octopus to taste even before it could consume any food material. It has the power to regenerate lost arms and it has excellent vision. Most organisms living in water do not have good eye sight but the octopus is an exception. They live mostly in sea dens and are effective predators. They also have excellent capabilities to defend themselves although they lack hearing sense. Their food consists of snails, fish and also sometimes they eat other octopi. Octopus can gain access even into shelled prey. They have so much power in their arms with which they can break open a shell or with help of toxins they can damage the tissues of the prey. Truly Octopus is a rare variety of sea organisms. I feel they will survive easily with their extraordinary natural powers. I have started to learn more about Octopus through Octopus.com.Their site is dedicated in providing all the information related to Octopus. You could get all the information about the anatomy and physiological characteristics of octopus. They have a wide collection of books about octopus explaining each and every category. I feel that this site is the best as they provide the best information about the most strange sea organism on planet.
