To survive, great white sharks have evolved several behavioral adaptations, including flexible activity patterns, migratory habits and social hierarchies. However, great white sharks are also intelligent hunters, and their most important adaptation is their use of different strategies for different
Sharks are fish, but unlike other fish, their skeletons are made of cartilage rather than bone, and instead of smooth, flat scales they have sharp, tooth-like scales called denticles. Scientists believe that sharks are 200 million years older than the oldest dinosaur, meaning they have been around f
An amazing fact about sharks is that the skins of females are much thicker than that of males. This is because male sharks tend to bite the females during mating. In its lifetime, a shark can go through about 30,000 teeth.
Some fun shark facts include that they have no bones, they have skin like sandpaper, have extraordinary sensory skills and teeth that are constantly being replaced. Most sharks never stop swimming and some species give birth to live young, called pups.
Sharks are fish, but they belong to the group called Chondrichthyes, or cartilaginous fish, which is a different scientific group than most types of fish. Common fish, such as tuna or salmon, all belong to the group Osteichthyes. The distinction is based upon the makeup of their skeletons.
Blue sharks are known for their distinct coloring, which allows them to blend in with ocean water. From above, the water appears darker and camouflages the shark's dark blue back, while its white underside resembles the sunlit ocean surface when seen from below. As a pelagic species, blue sharks inh
A shark is not considered a mammal. Sharks are considered members of the paraphyletic group of organisms that contain gills, or in other words, fish.
Whale sharks are the largest fish in the sea and are found in tropical waters that are both deep and shallow. Even though they are huge animals, their diet consists mostly of tiny organisms called plankton. They also eat krill, jellyfish, squid and smaller fish.
Whale sharks are the largest living fish, with a maximum weight of 34 tons and a maximum length of 67 feet. They are filter feeders equipped with special filter structures in their enlarged gills. They have a global distribution and migrate great distances but prefer to live and feed in warmer coast
Sharks have the ability to see, but they cannot see colors. Dolphins, whales and other aquatic animals are also color-blind. Marine animals' survival is not dependant on the ability to see color, but rather the ability to see contrast in colors.
