NATURE OF HUMAN OCEAN
The
clown fish (also known as the anemonefish) is a small species of fish that is
found around tropical coral reefs.
The most commonly known species of clown
fish is orange with white markings but clown fish can be found in many
different colours and can also differ in shape.
There are 28 recognised species of clown fish
that are found in the Indian and Pacific Oceans. The clown fish is also found
as far north as the Red Sea and inhabits the Great Barrier Reef, on the
Australian east coast. The clown fish was made most famous from the popular
children's film Finding Nemo . Aquatic stores and clown fish breeders reported
a significant increase in the popularity of the clown fish although many people
did not realise the work that goes into keeping marine fish so sadly, the
majority of clown fish bought at the time quickly died.
The
clown fish is also famous for it's seeming immunity to the stings of the sea
anemone.
Most
clown fish are found either in or around sea anemones which the clown fish
inhabits both for protection from predators but also the readiness of food.
Clown fish inhabit a single sea anemone in groups that include the breeding
male and female and a number of younger male clown fish.
All
clown fish are born male and develop female reproductive organs when needed.
When the female in the sea anemone group dies, the dominant male becomes female
and breeds with one the males that is inhabiting the same sea anemone. Female
clown fish lay their eggs on a flat surface close to the sea anemone which they
inhabit. The female clown fish can lay hundreds or thousands of eggs at one
time depending on the species.
Clown fish lay their eggs around the same time
as a full moon and the male clown fish guards the eggs until they hatch just
over a week later. Clown fish are omnivorous animals meaning that they eat both
plants and animals. Clown fish eat a wide range of food such as algae,
plankton, molluscs and small crustaceans.
The diet of the clown fish is however largely
dependent on the species of clown fish and what food is available in the area
which they inhabit.
Due
to their small size, clown fish are preyed upon by a number of predators but
can be difficult to catch are they often retreat into the safety of the sea
anemone. Large species of fish, sharks and eels are the main predators of the
clown fish in the water but the human is the biggest overall threat to the
clown fish as they are caught to keep in tanks and aquariums.
Despite the rising levels of pollution in the
world's oceans and destruction of the habitats on the ocean floor, clown fish
are not considered to be a threatened species of animal mainly because they lay
so many eggs at a time. Even though not all of the clown fish eggs will hatch,
a vast number of clown fish fry hatch in every spawn meaning that clown fish
numbers remain high in the wild.
