Bull Shark (Carcharhinus leucas) Information, species classification and other Bull Shark information.

Bull Shark - Carcharhinus leucas

Many people believe that these are the "most dangerous" of all sharks: They are fast, strong and are endowed with teeth which need not fear comparison with those of its tiger or white shark counterparts.

The real problem with this shark species is more the fact that they like to spend time in shallow waters close to the shore and often also in river estuaries. Rivers carry fresh water and much live food which often dies when coming into contact with salt water. The broad palette of food attracts a wealth of organisms - including sharks.

However, only few species of sharks can survive in brackish water and this requires physiological adaptations which can stress the shark's body. The mixture of fresh and salt water is mostly enriched with a high concentration of organic and anorganic substances, resulting in limited visibility. The bull sharks which roam these regions must not only cope with physiological adaptation but also with an overdose of electrical fields which stem from all these substances.Limited visibility can lead to confrontations with humans and to accidents because their biting inhibition is considerably reduced due to the unusual environmental conditions.
