An overview of the tiger shark

Sharks can unhinge their jaws and destroy large prey with their rows of razor sharp teeth. But even though sharks' jaws and teeth make them fierce predators, it's their sensory perception that truly makes them great hunters. Sharks can track large prey by following their low-pitch sounds, plus they can smell blood in the water from miles away. Sharks also have two extra senses which allow them to sense electrical fields and vibrations in the water.

Isurus oxyrynchus Shortfin Mako and Isurus paucus Longfin Mako The genus name Isurus comes from the greek words meaning "Equal Tail" The species name oxyrynchus comes from the greek words meaning "Sharp Nose" The species name paucus comes from the latin word meaning "Few" Taxonomy: Paleocene to Recent The Isurus genus first appears in the Paleocene.

By the Miocene it branches into the modern Mako sharks and the White Sharks. Nearly Global The Shortfin Mako shark has a global distribution in offshore temperate and tropical waters.

The Longfin Mako shark is less common and less is known about them. However, they have a nearly global distribution in offshore tropical and semitropical waters.

Tiger Shark - Shark Facts and Information

The largest Longfin mako accurately measured had a length of Fish The diet of a Mako shark is almost entirely fish, smaller sharks, and sometimes squid.

They have very long and thin teeth, ideal for grasping onto fish.

Mako sharks have a dark blue dorsal surface and a white underbelly. They are very slim and hydrodynamic. The Longfin mako looks very similar to the Shortfin mako but has larger fins and eyes.

Speed Racer Mako sharks are the fastest of all sharks. For comparison, an Olympic swimmer can swim at speeds around 5 mph. High Jump Shortfin Mako sharks are known to jump out of the water.

They can leap to incredible heights of over 30 feet! Based on studies of tagged individuals, Shortfin makos may migrate to warmer waters in the winter. Both Makos are very similar, but the Long-fin Mako has a slimmer body and larger fins.

Mako Shark Range, Diet, and Size Makos are pelagic, they prefer the open ocean, and live in tropical and temperate waters worldwide. They are also very hydrodynamic, and are among the fastest fish. Depending on the source, they can attain speeds anywhere from 20 mph to 30 mph. According to the FMNHthe average adult size is around 10 feet 3.

Because of their size and speed, Makos are a popular sport fish. Shortfin Mako Sharks Isurus oxyrinchus. The fossils and photos are used by permission of Bill Heim. Due to the nature of mainly isolated teeth being found and a wide range of tooth morphology in mako sharks, research on mako shark evolution appears to be convoluted and incomplete.

A detailed account of Mako shark evolution is beyond the scope of this page. The section below gives a very general overview of Mako shark evolution.

Mako sharks first appear in the fossil record as the genus Isurolamna in the Paleocene possibly around 60 million years ago. In the Eocene, around 55 million years ago, the Isurus praecurser Macrorhizodus praecursor genus branches from the makos. This "Macrorhizodus" genus continues to diversify throughout the fossil record.

The teeth broaden over time and eventually branch into the White Sharks Cosmopolitodus and Carcharodon. Some time in the late Oligocene, modern looking forms of mako sharks appear.

By the Miocene, there are at least two species of Mako sharks: Based on an associated skeleton from Europe, the escheri species appears to be more closely related to the Cosmopolitodus and Carcharodon generas than the Isurus genera.

Although more closely related to the White Sharks, it still had some differences, and was given the genus Carcharomodus Kriwet et al, Mako (Isurus) Shark Facts and Information - Including Evolution and Fossil Species.

The tiger shark (Galeocerdo cuvier) is a species of requiem shark and the only extant member of the genus Galeocerdo. It is a large macropredator, capable of attaining a length over 5 m (16 ft 5 in). Populations are found in many tropical and temperate waters, especially around central Pacific islands.

A scuba diver above a Whale shark. The Whale shark is the largest fish in the world; the basking shark is the second largest fish. There are many different species of sharks that range in size from the size of a person's hand to bigger than a bus. Fully-grown sharks range in size from 7 inches ( Shark Anatomy Label the shark external anatomy diagram.

Sharks deftly maneuver through the water by adjusting the angle of their fins. Sharks don't have a swim bladder like most other fish, so they regulate their vertical position by moving forward. Another unique aspect of the shark's body is that its skeleton is composed of cartilage rather than bone.
