Fish - Fish are vertebrates
which live in water and respire with gills. Fish are found in every
ocean, lake, river and stream in all corners of the globe, in many
sizes, colours and species. There are over 33,000 species of fish.
Slug - Slug is a mollusk
that belongs to the class Gastropod. There are thousands of species
of slugs that can be found all over the world. Slugs can reach ¼
inch to 10 inches in length, depending on the species. Slugs play
important role in natural ecosystems. They remove dead, decaying
plant matter and serve as important source of food for various
species of animals.
Sea Dragon - Sea dragon is
a small, delicate fish found in the tropical coastal waters of south
and west Australia. Sea dragons look similar to and are closely
related to sea horses. Sea dragons are carnivorous animals. They
hunt crustaceans, plankton, shrimp and small fish.
Whelk – Whelk is a common
name that is applied to various kinds of sea snail. They have
historically been used or are still used, by humans and other
animals for food.
Flame Scallop - Flame
scallop is a species of saltwater clam. This species is found in the
Caribbean Sea. It is similar in appearance to the Indo-Pacific
electric flame scallop. Flame scallops have a rough shell and a red
mantle. Flame scallops can reach 3 inches in length.
Staghorn Corals - Staghorn
Coral is a branching, stony coral with cylindrical branches ranging
from a few centimetres to over two metres in length and height. It
occurs in back reef and fore reef environments from 0 to 30 m depth.
Staghorn coral is found throughout the Florida Keys, the Bahamas,
the Caribbean islands and the Great Barrier Reef.
Tube Sponge – Tube sponge
has long tube-like structures of cylindrical shape. Although they
can grow in a single tube, they often grow in large groups of up to
22 tubes. These sponges mostly live in the Western Atlantic Ocean.
These sponges take hundreds of years to grow and never stop growing
until they die. The population density of these sponges is going
down because of oil spills and other pollution.
Sea Urchin - Sea urchins
are easily recognised type of marine animals. They have globe-like
shape of the body that is covered with large number of long spines.
Bony plates form shell that provides protection for the soft inner
parts. They are usually 1.2 to 3.9 inches in diameter. Sea urchins
usually live in warm waters on the rocky bottom or close to the
coral reefs.
Sea Sponge – Sea Sponges
are animals of the phylum Porifera. They are multicellular organisms
that have bodies full of pores and channels. They do not have
nervous, digestive or circulatory systems. Instead, most rely on
maintaining a constant water flow through their bodies to obtain
food and oxygen and to remove wastes.
Corals - Corals are sessile
marine invertebrates that belong to the phylum Cnidaria. Corals can
be found in the warm tropical waters all over the world. Most corals
reside in shallow, coastal waters. Corals are made of millions of
tiny, dead and alive, sac-shaped creatures called polyps.
Seal - Seal is of
web-footed aquatic mammals that live chiefly in cold seas. Seals are
carnivores, eating mainly fish, though some also consume squid, other
mollusks, and crustaceans. Seals have been hunted for their meat,
hides, oil, and fur.
Octopus - Octopus is a
genus of cephalopod mollusc in the order Octopoda. They have two
eyes and four pairs of arms with suckers. They have a hard beak,
with the mouth at the centre point of the arms.Octopus have no
internal or external skeleton.
Cuttlefish - Cuttlefish is
a type of marine invertebrate that belongs to the group of
Cephalopods. Cuttlefish can reach 6 to 20 inches in length.
Cuttlefish has ability to quickly change colour, texture and pattern
of the skin on the body thanks to the millions of pigment cells,
connected with muscles in the skin. Cuttlefish has very large brain,
and it is one of the most intelligent marine invertebrates.
Turtle - Turtles are
reptiles having a hard shell that protects them like a shield, this
upper shell is called a ‘carapace’. Many turtle species can hide
their heads inside their shells when attacked by predators. Turtles
spend large amounts of their lives underwater.
Crocodile - Crocodiles are
large aquatic reptiles that live throughout the tropics in Africa,
Asia, the Americas and Australia. Crocodiles live in rivers, lakes &
dams. Their colours range from brown to grey and have different
patterns covering them. They have sharp claws and teeth. They can
hold their breath for a maximum of about two hours underwater.
Dolphin - Dolphins are
aquatic marine mammals part of the toothed whales. Dolphins are from
1.5 to 4 metres long. Although dolphins are widespread, most species
prefer the warmer waters of the tropic zones. Dolphins feed largely
on fish and squid. Dolphins are often regarded as one of Earth's
most intelligent animals.
Whale - Whales are huge,
warm-blooded, air breathing mammals that live in the sea. There are
79 to 84 different species of whale. Many whales are toothless. They
use a plate of comb-like fibre called baleen to filter small
crustaceans and other creatures from the water.
Manatee - Manatee is the
large aquatic mammal. Manatees resemble to walrus or small whales,
but they are more closely related to elephants. Manatees are also
known as sea cows. They are grey or grey-brown in colour. Unlike
other marine mammals, manatees are strict herbivores. Manatees live
up to 60 years in the wild.
Dugong (Sea Cow) - Dugong
is a large mammal that lives its whole life in the sea. They are
sometimes called "sea cows" as they eat large amounts of
sea grass. Dugong can grow to about 3 m (10 ft) long and weigh as much
as 400 kg. They only come to the surface to breathe and they never
come up on the land. The dugong can live for up to 70 years of age.
Shark - There
are more than 350 different kinds of sharks. Sharks come in many
different shapes and sizes, but most are long and thin, with
powerful jaws. Their teeth are constantly replaced throughout their
lives.
