PRESENTATION OF
SEA ANIMALS

2. Any of numerous animals inhabiting the
sea including e.g. fishes and molluscs and
many mammals. . synonyms: marine
animal, marine creature, sea creature. types:
by-catch, bycatch. unwanted marine
creatures that are caught in the nets while
fishing for another species.

3. According to the World Register of Marine
Species, WoRMS, the total number of marine
species known to us is about 240,000 species
(2021 census). However, it is estimated that there
are 1.4 -1.6 million marine species on earth
(Bouchet, 2006.)

4. Marine life, sea life, or ocean life is the
plants, animals and other organisms
that live in the salt water of seas or
oceans, or the brackish water of coastal
estuaries. At a fundamental level,
marine life affects the nature of the
planet. Marine organisms, mostly
microorganisms, produce oxygen and
sequester carbon.

5. Three main groups of
ocean life are plankton, nekton,
and benthos. Plankton float in
the water. Nekton swim
through the water. Benthos live
on the ocean floor.

6. The small and microscopic organisms drifting or
floating in the sea or fresh water, consisting
chiefly of diatoms, protozoans, small
crustaceans, and the eggs and larval stages of
larger animals. Many animals are adapted to feed
on plankton, especially by filtering the water.

7. The largest group of nekton are chordates
and have bones or cartilage. This group
includes bony fish, whales, sharks, turtles,
snakes, eels, porpoises, dolphins and seals.
Molluscan nekton are animals like octopus
and squid. Arthropod nekton are animals like
shrimp.

8. Benthos, also known as benthon, is the community
of organisms that live on, in, or near the bottom of a
sea, river, lake, or stream, also known as the benthic
zone.Benthos refers to organisms living on the
bottom or associated with substrata. Terms
synonymous with benthic algae are Periphyton and
Aufwuchs. The nature of the habitat in which these
organisms are found depends on the habitats present
and on the size of the organisms

9. The funnily named whale shark gets its name for being a
shark which is as big as a whale. The whale shark’s size
is something to behold, and it is the largest living non-
mammalian species in the world. Its huge size helped it
rack up over 500,00 photos on Instagram. The largest whale shark on record
comprised a length of 18.8m. Whale sharks can be found in many countries
around the world, including in Australia, Asia and South America. Because
there has been such a significant decline in the whale shark population in
recent years, the exact number of the species alive is unknown, with an
estimated population size between 119,000 and 238,000. The biggest threats to
whale sharks come from the loss of habitat due to overfishing, coastal
development and pollution.

10. The sailfish is a marine animal that is
known both for its pointed bill (like a
swordfish), and its tall, sail-like dorsal fin
which inspired the name ‘sailfish’.
The sailfish is thought to be the fastest fish in the ocean, but has managed
to be captured on camera and tagged by over 250,000 Instagram users,
which is pretty impressive! This reputation, along with their spectacular
dorsal fin, makes sailfish a popular target for game fishers, who have
affected the population density of swordfish in some areas. The species is
not under threat of becoming extinct but is affected by the changes in sea
temperature and marine ecosystems that are caused by climate change. The
best way to help prevent damage to our oceans is by reducing the amount of
single-use plastic we use to avoid polluting

11. Queen Angelfish are one of the Caribbean coral reef’s
most colourful fish, with over 200,000 images of the
species tagged on Instagram proving that they are also
one of the reef’s most popular photo subjects . The
The royal title bestowed on this tropical fish comes from the blue-ringed
black spot on its head, which makes it look as though it’s wearing a crown.
Angelfish are fairly shy, and often only found on their own or in pairs
amongst their reef habitats. They are larger than most other fish who live
amongst coral reefs and can grow up to 18 inches in size. Their colourful
blue, yellow and orange scales mean that they are frequently captured and
taken from their natural habitat to be displayed in aquariums.
