Types of Sharks – Information on Different Species

Sharks are a species with an infamous reputation. Some species have been known to attack and prey on human beings throughout the years. Countless movies and books have portrayed them in a notorious manner and as a stereotype, we have seen one common depiction of how sharks look like. However, did you know that there are 470 species of these groups of fish? Considering the vastness of the ocean, this number should no longer come as a shock. In addition, not all the shark types are dangerous and attack humans. Some of them would rather be left alone or look for food at the depths of the ocean. Not your typical idea of how a shark acts right? Through this article, let us be enlightened about some of the most well known types of sharks. Here they are:

Tiger Sharks

Tiger sharkThe name implies the white stripes that begin to appear on these sharks’ dark backs while on their juvenile stage, the stripes fade away as they mature. Tiger sharks are considered to be one of the most dangerous sharks as they have been known to attack humans even when unprovoked. They are known to be the most aggressive species of sharks to attack humans in Hawaii. Their senses of smell and sight are excellent, they have greatly serrated teeth and powerful jaws – these characteristics make them the voracious hunters that they are. They devour almost about anything that they can catch. These sharks are even capable of crushing the exoskeleton of different shellfish. Objects such as old tires and other forms of garbage have been discovered in the stomachs of some tiger sharks that have been captured. These sea predators can grow from 10 to 14 feet and weigh 385 to 635 kilograms.

Blue Sharks

They have a slender body with long and pointed fins, as well as an elongated tail. Their eyes are large; they have pointed snouts and serrated teeth. Blue sharks are known to be adept swimmers and can travel long distances in just a short amount of time. They are fond of attacking schools of fish such as sardines and herring for their diet; however they are known to primarily feast on squid. Even though they are usually found on deep waters, blue sharks are considered to be dangerous to human beings. There have been records of these sharks attacking humans. Considering their swiftness and the strength of their jaws, it is best for us to stay away from these sharks if we don’t want to end up as someone else’s meal.

Angel Sharks

If you haven’t, then let us go further into detail about this type of shark. Angel sharks have flat bodies that are similar to that of rays; hence they are usually mistaken to be some other sea animal. You can find their eyes on top of their heads and they have fins that are long and wide, thus their name. Their brownish-gray color makes it easy for them to dwell and bury themselves on the ocean floor. This is where they wait until a prey that they can ambush gets within their reach. Fish and mollusks comprise most of their diet as they are not a carnivorous bunch.

Hammerhead Sharks

Hammerhead SharksHammerhead sharks got their name from their wide, long and almost rectangular heads that resemble hammers. The eyes of these sharks can be found on both ends of the “hammer”. They have teeth that are serrated and triangular and a strong sense of smell, making them good hunters. These sharks are known to be aggressive predators, but they are not considered to be dangerous to humans unless provoked. They are fond of feeding on other fishes, sharks, squids and crustaceans. However, they are known to be particularly fond of sting rays. Sharks have a group of sensory organs called ampullae of Lorenzini which are an array of electroreceptors, allowing them to identify electrical fields in the surrounding water. These sensory organs are notably more sensitive in hammerhead sharks, thus it becomes easier for them to sense the presence and catch a nearby prey.

The list for the different types of sharks certainly doesn’t end here. Some of the common shark types are great white sharks, mako sharks, whale sharks and the list can go on and on. It certainly is interesting to take a look into these sea creatures and consider how our oceans are so rich in diversity.
