Humpback Whale (Megaptera Novaeangliae)
Its scientific name was given to this species in
1781 by a German naturalist named Borowski. Humpback whales belong
in the Balaenidae family and are categorized as baleen whales
(baleen are the series of plates used to strain food from 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 to only
take a mighty slurp of "krill soup," close it's mouth, and expel the
excess water through the 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 populations,
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)
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.
Bottlenose Dolphin (Tursiops Truncatus)
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.
Thornback Ray (Raja Clavata)
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.
