Sharks

sea dangerous animal Many kinds of sharks live in the warm waters around Australia, like the Whale shark, the Basking shark, the Oceanic White-Tip shark, Dusky shark, Leopard shark and the Hammer shark.. However the largest and most scary, the Great White, is also the most common shark in Australian waters. The smallest shark is the Dwarf shark, and the largest is the Whale shark. As dangerous as they can be, most sharks will not attack humans unless bothered, and actually, sharks themselves don’t have an easy time of it. Dolphins attack sharks in groups to protect their young. The shark's biggest enemy is humans who attack sharks for food, sports and to protect beaches. Sharks appear to be smooth, but up close they have sharp points that are tough. A sharks' body is also streamlined so they can move quickly and easily through the water. Sharks eat other sharks, seals, fish, baby dolphins, birds and sometimes humans…mostly because they mistake them for seals.

The Sea Wasp sea dangerous animal

The Sea Wasp or the box jellyfish is one of the most deadly stinging animals in the sea. The sea wasp has a large transparent body shaped like a box or a bell, that can be as large as a bucket, and can weigh as much as five pounds. A cluster of 16 long semi-transparent tentacles stream out from under the bell of the box jellyfish. Millions of stinging capsules cover each of the tentacles. The stinging capsules discharge lethal poison into the skin of any creature that touches them. Children who have been stung by the sea wasp have died within minutes of being stung

The Portuguese Man-Of War is another stinging jellyfish, and although it is much more widespread and common than the box jellyfish or sea wasp, it is not as deadly as the sea wasp. The Portuguese man-o-war is commonly called the blue-bottle in Australia. Actually, the Portuguese man-o-war is not a single marine animal, but consists of a large colony of smaller marine organisms. The blue-bottle gets its name from the body, which really is a large, gas- filled float. The float has a crest, that is used much as a sail to propel the colony across the water when the wind blows. Although the sting from the Portuguese man-o-war is not deadly to humans, a person who comes into contact with a Portuguese man-o-war or blue-bottle will still experience a sharp severesea dangerous animal pain.

The Blue-Ringed Octopus sea dangerous animal

The Blue-Ringed Octopus is another one of the smaller, but more deadly marine animals that inhabit the coastal waters around Australia. The blue-ringed octopus is normally light in color, with dark brown bands over its eight arms and body, with blue circles superimposed on these dark brown bands. When the octopus is disturbed or taken out of the water, the colors darken and the rings turn a brilliant electric-blue color, and it is this color change that gives the animal its name. The blue-ringed octopus secretes a very deadly poison, either by biting with its parrot-like beak, or by squirting the poison into the water surrounding it. The direct bite from the blue-ringed octopus is usually painless, but the deadly effects of the poison will be noticed immediately. The poison apparently interferes with the body's nervous system. The victim will immediately experience numbness of the mouth and tongue, blurring of vision, loss of touch, difficulty with speech and swallowing, and paralysis of the legs and nausea. If the victim does not receive medical treatment immediately, full paralysis may occur within minutes, followed by unconsciousness and death due to heart failure and lack of oxygen. There is no antivenom for the poison from a blue-ringed octopus. It is usually necessary to perform continuous CPR on a victim until the effects of the venom have subsided. This may take several hours, but it may mean the difference between life or death for the victim.
