evolution

Not only do the evolutionary features define the look of a shark, but also determine how they survive in the wild. Not all sharks will constantly be searching in a particular area of the ocean for their food. There are three general types of sharks that will move according to the form and function of their body. This includes some sharks that will move at the upper part of the ocean and will move at a slow pace, sharks that will be towards the middle of the ocean and will have a powerful force while swimming and sharks that stay at the bottom of the ocean, moving slowly and finding their food on the ocean floor.

Hammerheads part 2

 Hammerheads are found in tropical and temperate seas throughout the world, in both coastal and offshore waters. The smooth hammerhead is found around the entire coast of WA, but the great hammerhead and smooth hammerhead are rarely seen south of the Houtman Abrolhos Islands. The Montebello Islands Marine Park, the proposed Dampier Archipelago Marine Park and the Rowley Shoals Marine Park are great places to see them.

hammerheads part one

 Three species of hammerhead shark are found in north-western Australia but only one, the great hammerhead (Sphyrna mokarran), is considered dangerous. The scalloped hammerhead (Sphyrna lewini) and smooth hammerhead (Sphyrna zygaena) are quite timid and the similar-looking winghead shark (Eusphyra blochii) is considered harmless. Despite the fear they have traditionally engendered, public opinion is now slowly swinging around in the sharks’ favour. These days, most divers who see a hammerhead shark regard it as a rare and exciting experience. People are coming to realise that shark attacks are relatively rare (more people in Australia die from bee stings) and usually occur only when sharks mistake people for food species such as seals.

The biggest shark is the whale shark (Rhincodon or Rhiniodon typus), which can be up to 50 feet (15 m) long. It is a filter feeder and sieves enormous amounts of plankton to eat through its gills as it swims. It is also the biggest fish.

The second biggest fish and shark is the basking shark (Cetorhinus maximus) which is about 40 feet (12.3 m) long and is another filter feeder.

The biggest meat-eating shark is the Great white shark (Carcharodon carcharias) which grows to be up to 21 feet (6.4 m) long. Great whites up to 37 feet (11.3 m) long have been reported, but not verified.

smallest sharks

The smallest sharks are: 

Dwarf Lanternfish (Etmopterus perryi), which is about 7 1/2 to 8 inches (19 - 20 cm) long for fully-grown females and 6 to 7 inches (16 - 17.5 cm) long for adult males

Spined pygmy shark (Squaliolus laticaudus), which is about 8 inches (21 cm) long for fully-grown females and 7 inches (18 cm) long for males 

Pygmy ribbontail catshark (Eridacnis radcliffei) , which is about 6 to 7 inches (15 - 16 cm) long for fully-grown females and 7 to 7 1/2 inches (18 - 19 cm) long for males.

that is freaking small, i kinda wish i had one in a fish tank, it would be so cute, yet ferocious!

Normally, sharks eat alone.  But sometimes one feeding shark attracts others.  They swim up as quickly as possible and all begin to try to get a piece of the prey.  They bite wildly at anything that gets in their way -- even each other.


The great white shark rarely partakes in feeding frenzies.


Almost all sharks are "carnivores" or meat eaters.  They live on a diet of fish and sea mammals (like dolphins and seals) and even such prey as turtles and seagulls.
