Shark Habitat
Although they inhabit tropical and temperate oceanic waters, some sharks have an incredible adaptability that allows them to enter cold areas and bodies of freshwater, such as rivers and lakes.
Shark Distribution
More than 450 shark species dwell throughout the oceans around the world at different latitudes, depths, temperatures, or salinity levels, but there are areas where they concentrate more because they find the optimum conditions to live.
Shark Feeding From plankton to sea lions and even other sharks, the diet of these fish is very varied. While some of them are filter-feeders, others must stalk and hunt their prey.
Shark Reproduction The reproduction of sharks is one of the most complex of the animal kingdom since it is carried out in three different ways according to the species. However, they all have low fertility and late sexual maturation.
Shark Senses All sharks depend on their senses to survive in the challenging environment where they inhabit, especially when it comes to food. Animals with such requirements have more than five senses, unlike humans.
Shark Anatomy
The collective imagination believes that all sharks are large, robust and with huge teeth, but not all fit this description. However, they have a very different anatomical structure than other fish.
Shark Behavior
Chondrichthyes show a unique behavior for each stage of their life, like reproduction, migration or feeding. Also, not everyone has the temperament of a tiger shark; Certain species are timid and even docile.
Shark Tails
It is a crucial element within shark’s anatomy. The tail of the sharks is adapted to the environment and lifestyle of each species, providing balance, speed, and direction.
Shark Communication
Although they cannot produce vocalizations, sharks have other forms of communication that are not always easily distinguishable. Their many senses play a significant role at the moment of coincidence with other sharks.
Shark Evolution
Research has revealed that the existence of sharks dates back more than 400 million years, which means that their ancestors evolved to end in the species that we know today. While ancient sharks were very different than those today, their surviving capabilities are amazing.
Shark Social Structure
They appear to be completely antisocial creatures without any contact with other comrades, but there is evidence of species exhibiting social structures and hierarchies, especially in the mating period and in some food searching situations.
