Why Do Fish Have Slim Tapering Bodies?

The shape of a fish enable them slip through the water easily. If you consider that most creatures spend all their lives in water have sleek, streamline shapes and slim tapering bodies which helps them to swim. As you maybe aware fish comes in many different forms, size and shapes. For instance there is the Ocean Sunfish. This fish is around 14 feet high making it the tallest fish including their long back and belly fins. The Ocean Sunfish can weigh up 2 tonnes or more.

World's Longest Fish

Then there are fish that are long such as the giant eel-shaped fish known as the Oarfish. The Oarfish is the world's longest fish which can grow in length of over 20 feet long or more. There have been record of individual Oarfish being 46 feet long. The Oarfish has a ribbon-like shape which helps it to glide through the water.

Carpet Sharks

Carpet Sharks are masters of hiding. Many sea creatures have bodies with colours, shapes and patterns that blend in with their surroundings. This natural disguise, or camouflage, allows them to hide from their enemies and also makes it good for them to sneak up on their preys. Carpet Sharks live and hunts on the sea-bed.  The pale blotchy colours of the Carpet shark help it hide from their preys, such as small fish and crabs, as they lie motionless on the bottom of the sea. Hence the name: Carpet Shark.

There are other fish such as Herrings, Mackerels and many other types of fish that swims near the surface of the great oceans which have dark backs and pale bellies. These colourings are known as countershading which works to cancel out the effect of sunlight shinning on their bodies from above and therefore, helps the fish to hide even in the open sea water.

Colourful Fish

Most fish that lives in tropical sea water are brightly coloured. But what is the reason why tropical fish are colourful? These fish lives amongst the coral reef of the tropical seas. Colouring help these fish to hide among the brightly coloured coral reefs and within the dark shadow of the coral. Colours also help these fish to stand out clearly in the open water. In the breeding season, when they are looking for mates for breeding, they want to be seen and notice by their forthcoming mates.  To attract their prospective mates they swim and dart around in the water to make themselves obvious

Coral Reefs

Coral reefs are made by tiny creatures called polyps that lives in colonies mainly in tropical sea water. Polyps are shaped like small sea anemones, but have a hard, chalky cup-shaped shell to protect their bodies. When they die, the shells remain and new polyps grows on top of them. Overtime billions of shells build up to form a coral reef. On corals there are what is known as Dead man's fingers, and dead man's fingers are a species of softy coral that grows on rocks. Each coral colony is made up of thousands of polyps that forms a fleshy mass that looks like a rubbery hand. When pieces of rubbery hand washes up on a sea-shore. It is quite possible that it can give swimmers a big fright to see something that resembles a dead man's hand or finger.

Great Barrier Reef

One of the biggest coral reef is known as the Great Barrier Reef off the north-east coast of Australia. The Great Barrier Reef is the world's largest coral stretching for 1,200 miles. It is the largest structure made by living creatures. The Great Barrier Reef is the home several colourful and spectacular sea animals, including more than 1,500 different kinds of fish.  One of the biggest danger to coral reefs is the Crown-of-Thorns starfish. Crown-of-thorns is a coral reef killer. The crown-of-thorns starfish fastens itself to the living coral, sticks its stomach out, and releases juices that digest the polyps. When only the coral shells are left, the crown-of-thorns starfish moves on to another area of the colony. This creature can kill a large patch of coral in one day. Crown-of-thorns starfish has destroyed massive areas of the Great Barrier Reef. 

Mysteries of Deep Sea Fish

Even today in the 21st century scientist know very little about deep-sea fish. This is due to the fact they often experience difficulties descending to the bottom of the ocean. Most deep-sea fish will not survive in the atmosphere of the surface if they are brought up from the depths of the sea. Some will even explode, because their bodies are so built that they are only able to withstand the great pressure of the ocean depths.  More than a century ago scientist believed that life could not exist in the very deep oceans. Now they know that creatures do survive in the dark depths of the oceans, but conditions are extremely harsh. At 3,330 (1000m) below the sunlit surface, the water is pitch-black and ice cold. All deep-sea fish must be able to withstand the great pressure caused by the weight of the water on top of them, which would kill all surface creatures. Many deep-sea fish look like monsters just as if they were out of some horror movie, with very large heads,  extra large mouths, fierce looking teeth and long thin bodies. Yet, on the contrary, these deep-sea horror creatures are quite small, less than 1 foot long.

Viperfish, Gulper Eel and Black Swallower

In the black depths of the sea many deep-sea fish sense their prey by smell, taste and touch. A line of nerve running down the fish's body picks up the vibration in the water caused by other creatures swimming. Some of the deep-sea hunter fish have long touch and taste sensitive tentacles trailing from their jaws. Some fish such as the gulper eel never gets hungry. In the depths of the sea there are no water plants and very few creatures lives down there, therefore, food are very scarce in the dark depths of the ocean, so fishes' meal are few and far between. Fish such as the Gulper eel and the Viperfish have very large stretchy stomachs that can expand to fit any victim. Another deep-sea fish known as the Black Swallower, can swallow and digest a fish twice its size.

What is a Chimera?

According to Greek Legend, the chimera was a really terrible monster of an animal. The chimera is a strange deep-sea fish that look as if their bodies was assembled from the parts of other land animals. The chimera is a monster that look as if it was fitted with a lion's head, a goat's body and a dragon's tail. The animals have very large head with staring eyes like bushbabies, and buck teeth just like a rabbit. The chimera animal have long thin tail just like a rat's tail.

Captain Ahab and Moby Dick

Herman Melville writer of the classic Moby Dick novel, tells the story of Captain Ahab and his hunt for the great white sperm whale that tore off his leg. In his ship, the Pequod, Captain Ahab and his crew of sailors set sail all round the world in search of the great white sperm whale Moby Dick the whale that tore off his leg. When Captain Ahab and his crew finally caught up with Moby Dick, they struggled for days to catch him. Captain Ahab finally harpooned Moby Dick, the great white monster just as he sunk the ship, and the unfortunate Captain Ahab is dragged down to a watery grave.

Mouthbrooders

Few fish look after their Babies, but fish known as mouthbrooders are an exception to the rule. Mouthbrooders such as the Sea Catfish, protects their young by hiding them in their mouths! In the world of sea catfish, the males are the caring parent. The sea catfish babies swim in a cloud near their father's head. Sea catfish babies swim close to their father's mouth so that they can scoot inside his mouth when danger threatens.

Dinosaurs of The Oceans

Blue Whales are the giants of the oceans. The Blue Whale is the largest animal ever to have lived on planet Earth. It is four times the size of the biggest dinosaur. The adult Blue Whale can measure up to 100 feet long, and weigh 200 tonnes, which is as much as 60 Elephants. The female species of the Blue Whale are even bigger than the male species.
