Transcript of Seahorse

The ocean is sick. Its most productive ecosystems are dying, its coastlines and beaches are being destroyed, and its waters are polluted. Invasive species are taking over more seas, acidity is increasing, water is warming, food webs are fraying, and key species and populations are vanishing.

Even though the seahorses are a beautiful creatures they are at risk of extinction due to dead zones, blast fishing, marine litter, and over fishing .

Seahorse Information Report
Seahorses inspire an almost universal reaction of wonder and delight. They have been favoured in fairy tales as friendly denizens of the deep, the mythical steeds of mermen, and have been prized as aquarium specimens and sought after for medicinal uses. Their unusual body form evokes comparisons to other animals; seahorses have been said to have the snout of an aardvark, the spines of a puffer fish, the pouch of a kangaroo, the independent eyes of a lizard, the prehensile tail of a monkey, the armour-plated body of a stegosaurus, and the colour-changing capability of a chameleon
The scientific name for the Seahorses is Hippocampus. Hippocampus comes from the greek words 'hippos', meaning 'horse' and 'campus' meaning 'sea monster'.
GENERAL CLASS
The smallest seahorse in the world is so tiny it’s no bigger than a baked bean.
Seahorses come in many different colours and sizes. The most common size of a seahorse can be as small as one and a half inches tall. The largest ones are only about eight inches tall. The most common coloured seahorses are bright orange, bright yellow, red, fluro yellow and brown. Seahorses are covered with bony skin not scales. Some seahorses have a shape, size and colour that allows them to blend in perfectly with their coral habitat. Seahorses change colour to blend in with their surroundings. Some kinds of seahorse develop spiky bits that look like twigs sticking out of their body, and these help with camouflage. Seahorses change colour to match their surroundings. Seahorses have a small crown on them called a coral net. Seahorses change colour whenever they are seahorses can change colours in order to camouflage themselves into their environment.



APPEARANCE
Seahorses are found mostly in warm, shallow coastal seas.Seahorses live in sea grass, mangroves, kelp and coastal. In these places they are protected from strong currents, storms and some predators.
Habitat
Seahorses eat on brine shrimp, tiny fish and plankton. A seahorse sucks in food through its long snout. Seahorses have no teeth and swallow living animal’s whole. An adult eats thirty to fifty times a day. Baby seahorses eat a massive three thousand pieces of food per day. Seahorses have no stomachs It makes a loud clicking sound that you can hear from far away. Its jaws are long and hollow. They eat slowly so most of their life is spent finding food and consuming it. They always find more than enough food in their natural habitat so they don’t have to look for it They hunt in an ambush style using camouflage
DIET
CONCLUDING STATEMENT
A seahorse’s eyes don’t move together, so it can hunt with one eye and watch out for enemies with the other. Seahorse’s swim slowly in a upright position. It’s dorsal fin move’s it though the water by beating up to 35 beats per second. Seahorse’s have a curly tail, they use this to help them to stop in the water. When it wants to feed or rest it grabs a nearby piece of coral or seaweed with it’s tail. Seahorses use the volume of air in their swim bladders to move up and down in the water. Swim bladders are an air pocket inside their bodies The Seahorse cannot curl it’s tail backwards. The Seahorses pectoral fins (located on either side of their head) controls the steering and turning. The Seahorses fast beating dorsal fin enables them to hover in the water.
MOVEMENT
During mating season the male seahorse grows a pouch on its stomach. The bigger the pouch the more attractive to female seahorse because the bigger the pouch the more safe for the eggs that the female lays in the males pouch. The female would lay 2 000 eggs in his pouch it would mostly depend on how big the males pouch is as well. The eggs are fertilized in the pouch and the male will grow supporting veins around the eggs to give nutrition to the developing babies. About 2-6 weeks later young seahorses hatch and the male squeezes groups out of his pouch. This can take 2 days. The male seahorse is exhausted after all this. A male and female seahorse may mate for life however some don’t and find new mates for next mating season. The male would carry the eggs for at least 45 days and then the young will emerge fully developed. Young seahorses have to care for themselves when they’re born; they cling onto seaweed near the water surface.
