Dangerous Sea Creatures

Australia, also known as the biggest island in the world, is home to some pretty exotic flora and fauna. The diversity is truly astounding. However there are a few things that need to be known about wildlife on this continent, especially if you are planning to go for a swim in the sea. Some of the sea creatures can be quite toxic, deadly even, if proper precaution is not taken. This article will deal with some of the more dangerous sea creatures of Australia.

Dangerous Sea Creatures

The Bluebottle

The bluebottle, also known as the Portuguese man-o-war, is an unusual blue colored creature. This creature is actually a type of floating colony of hydroids. Bluebottles can reach very large sizes, over 100 meters in length, although this is rare. It will have long thick tentacles, which it uses to hunt prey. The problem is that these tentacles also have stinging cells. If it comes in contact with human skin, then expect severe pain and sweating in the affected area. These creatures are found in both Atlantic and Pacific oceans.

Box Jellyfish

Box jellyfish also known as the sea wasp, is deadly sea creature. If a person comes in contact with its tentacles, a cardiac arrest can happen within a few minutes. In fact this creature causes more fatalities in Australia compared to alligators, snakes and sharks. It has a square type of body and tentacles that can reach 80cm in length.

Irukandji Jellyfish

Yet another jellyfish found mostly in northern Australia is the Irukandji jellyfish. This one however, is quite small, measuring only around 3 cm wide. It is related to the box jellyfish, although not quite as poisonous. If a person comes in contact with one of these, they can survive if they get timely medical help.

The Stonefish

The stone fish gets its name because of its camouflage. It is found mostly around the Great Barrier Reef in shallow waters, and the camouflage resembles a stone. It has spines on its back which is capable of delivering toxic venom. If a person stands on one of these fishes, then it can be fatal. However, the venom takes 1-2 hours to take complete effect.

Blue ringed octopus

As the name suggests, this octopus comes with blue rings. At 20cm wide including its tentacles, it is relatively small. These creatures are extremely venomous, if a person comes in contact with one of its stinging tentacles.
