Its scientific name was given to this species in 1781 by a German naturalist named Borowski.


Octopus are invertebrate and mollusc. They can be found worldwide, in warm temperate waters. Sometimes, they are also known as 'devil fish,' even though octopuses are not fishes but are related to oysters and mussels. An octopus has a big round head, a pair of big eyes and eight suckered arms (tentacles). These tentacles are used to push them forward and moved fast in the water. Octopuses have soft body and are squid-like. They feed on small fishes and crabs. When an octopus senses danger, it inks its surrounding waters black to protect itself.

They are classified under the Delphinidae family, the largest family of Cetaceans (classifications of the genera and species in this family is constantly changing). Bottlenose dolphins can measure up to 3.9 meter, weighing around 150 kg - 650 kg. They can be identified easily for their sickle-shaped dorsal fin and dorsal fin and distinct short beak. They usually have dark grey body with lighter underside, grading to white. Bottlenose Dolphins 'see' by listening to the echoes bounced off by objects in the water to determine the location and characteristic of an object. The dolphins were made famous by the television show 'Flipper,' they are also popular for being playful and highly sociable.

They are characterized by their triangle or rhomboid-shaped body. The tails are slender and whip-like. These rays have a pair of eyes that protrude above the dorsal surface. These eyes have some degree of mobility. The large thorn-like spines on its tail and central position of the wings give this ray its name. Thornback rays are classified as a fish and are usually found in deep sea of about 185 meter in depth, Their teeth show sexual dimorphism, males have pointed teeth and females have flat, rounded teeth, they feed on crustacean and fish such as herring, sprats and flatfish. While swimming, Thornback rays undulates the enlarged pectoral fins, aptly called 'wings' and the tail acts as a rudder.
