Humpback Whale (Megaptera novaeangliae)

Its scientific name was given to this species in 1781 by a German naturalist name Borowski. Humpback whales belong in the Balaenidae family and are categorised as baleen whales  (baleen are the series of plates used to strain food from the seawater). Humpback whales have about 300 baleen plates, which are skater grey. These baleens hang from the upper jaw like a fringed curtain on both sides of the large mouth. Therefore, a humpback whale needs only take a mighty slurp of "krill soup", close it mouth and expel the excess water through its horny comb and its lips. It will swallow the filtered broth of food that remains behind. The back of a humpback body is black and normally shades to a white belly. The shade of black on the whales varies in different population s, according to locality. Their flippers are rather long and have serrated leading edges that indicate the fingers. Their dorsal fins are relatively large and are placed half down the back. They are followed by a series of hillocks which end at their tails.

Octopus (Octopus bimaculatus)

Octopuses 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 move 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 water black to protect itself.

Bottlenose Dolphins (Tursiops truncatus)

They are classified under the Delphinidae family, the largest family of Cetaceans (classification and species in this family is constantly changing). Bottlenose dolphins can measure up to 3.9 metre, weighing around 150 kg - 650 kg. They can be identified easily for their sickle-shaped dorsal fin and distinct short beak. They usually have dark grey body and 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 characteristics of an object. The dolphins were made famous by the television show "Flipper"; they are also popular for being playful and highly sociable.

Thornback Ray (Raja clavata)

They are characterised by their triangular or rhomboid-shaped body. The tails are slender and whip-like. These rays  have a paid of eyes that protrude above the dorsal surface. These eyes have some degree of mobility. The larger thorn-like spines on its tail and central position of the wings give this ray its name. Thornback rays are classified as fish and are usually found in deep sea of about 185 metres 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.
