It comes as no surprise that there are many different jellyfish species in our waters with 200 species already known. Of these 200 species there are 70 which we are aware of that will sting. Unlike other common sea creatures such as fish and crabs, jellyfish do not have heads, hearts or even a skeletal structure. We present a overview of a few different jellyfish.
Australian Spotted Jellyfish / White-Spotted Jellyfish
The Australian Spotted Jellyfish or White-spotted jellyfish (Phyllorhiza punctata) is a jellyfish which is commonly found in the South-western Pacific. This particular jellyfish feeds on different types of snail species. These jellyfish generally have a body diameter of between 45 and 50cm although some have been reported as being bigger with the largest reported size being a whopping 72cm in diameter. These jellyfish posses a mild venom and are not really any threat to humans. There is a concern when it comes to these jellyfish as they have the ability to consume not just plankton but also the eggs and larvae of some important fish species everyday whilst it filters up to 13,200 gallons of seawater. The bell of the jellyfish is covered in white spots which is how the jellyfish species got its name.

The Arctic Lions Mane is a very impressive and somewhat frightening jellyfish as it is the largest animal in the world. This monstrous jellyfish can grow in diameter by about 8 feet and have tentacles which trail up to 150feet below them. These jellyfish range in color from tan or orange to very dark purple. Generally with these jellyfish the lighter the color of the jellyfish the smaller the jellyfish is. As the name suggests, the Arctic Lions mane jellyfish is found mainly in the arctic sea. The Lions Mane jellyfish has a body which is divided into 8 sections, each section having anywhere from 60 to 130 tentacles which makes this one very intimidating marine creature indeed. The most common jellyfish found in waters throughout the world is the moon jellyfish. This jellyfish is transparent with spots or streaking on the upper side of its body. The moon jelly has a diameter ranging from 5 to 40cm wide and is carnivorous using its tentacles to capture its prey. Jellyfish are very fascinating creatures found in almost every natural body of water on the surface of the planet. These creatures have existed for millions of years and more than likely will continue to do so for millions more.
