Tiger Shark


The tiger shark is one of the most intriguing creatures in the sea. With its distinctive stripes and massive size, this apex predator is both fearsome and awe-inspiring. 

In addition to being skilled hunters, tiger sharks possess an incredible sense of smell. This enables them to detect even the faintest traces of blood in the water from miles away.

The Greenland shark is another giant shark in the world. It is a large, slow-moving fish found mainly in deep waters of the North Atlantic Ocean, from Labrador to Iceland and as far south as Massachusetts. The Greenland shark can grow up to 24ft long, with some specimens growing even longer! 

Although they have been around for centuries, very little is known about this mysterious creature due to its preference for living in cold depths of up to 3,000 feet. However, technology has enabled us better to understand their behavior and ecology in recent years.

Unlike many other shark species, the Greenland shark feeds mainly on fish and invertebrates in the deep ocean. They also scavenge for seals, whales, and even polar bears, although humans rarely witness this behavior.

The Greenland shark has an incredibly long lifespan – with some specimens estimated to be almost 400 years old! This makes it one of the longest-living vertebrate species on Earth.

Due to its remote habitat and secretive nature, this incredible creature is still relatively unknown among people outside of scientific circles. However, as our knowledge of its behavior increases, so does our appreciation for this mysterious giant of the sea.

Hammerhead Shark

The Hammerhead Shark is one of the largest species of shark in the world and stands out from the rest by its distinct, hammer-shaped head. This unique feature gives it an advantage when locating prey or navigating its environment. The Hammerhead is found globally in tropical and warm temperate waters, often near coral reefs or coastal areas. They are typically solitary creatures but sometimes gather in small schools during feeding times.

There are nine species of Hammerhead Sharks: Scalloped Hammerhead, Great Hammerhead, Smooth Hammerhead, Bonnethead, Winghead Shark, Smalleye Hammerhead, Scoophead Shark, Broad Hammerhead, and Dwarf Hammerhead. The Great Hammerhead is the largest of all species.

These sharks have a diet of mainly fish, but they are also known for their scavenging habits. They sometimes feed on other small aquatic animals, such as squid or octopus. They serve as a valuable food source for other animals in the ecosystem and are an integral part of the food chain in some regions.

The overfishing and habitat devastation people brought are why the hammerhead shark is a threatened species. Nonetheless, attempts are in progress to conserve this species to keep it safe from other populations. 



In conclusion, these seven largest sharks are fascinating creatures that continue to captivate people worldwide. From the Great White Shark’s powerful presence to the Greenland Shark’s mysterious nature, each species has unique characteristics that make them remarkable. 

Despite their intimidating appearance, many of these sharks play a crucial role in maintaining the ocean’s delicate ecosystem, making them essential for the health of our planet.
