Both basking sharks and great white sharks are massive creatures with distinct characteristics. There are, however, significant differences between the two species, including size, appearance, nutrition, and lifespan. In addition, one is bulkier and a filter feeder, and the other is smaller yet voracious.

Humpback whales are smaller than blue whales and are of a deeper blue color. Humpbacks also weigh much less and carry a hump on their backs which makes them stand out. On the other hand, blue whales have a mottled body, are bigger, and live longer. 

Hammerhead sharks have hammer-shaped heads and are one of the endangered shark species. There are two sorts of hammerheads: one with standard size and another with a larger size, known as great hammerheads. On the contrary, Great White sharks are one of the most vicious and aggressive shark species. Therefore, they are classified as apex predators.

Whales are majestic aquatic animals that can be either toothed or equipped with baleen plates, whereas blue whales solely have baleen plates. Besides, blue whales have a distinct blue-gray coloring, unlike most whale species that carry darker hues. In addition, blue whales have smaller dorsal fins than most whales. 

Fin whales and blue whales belong to the Balaenopteridae family and are known for their large size, grooved chest, unique dorsal fin, and unfused cervical vertebrae. There are several points of similarity between the two species but they also differ in terms of coloring, appearance, and general habitat requirements.

Some sharks swallow their prey without needing to chew. Other shark varieties, like the Port Jackson Shark, grind the prey using their broad back teeth. Some sharks are also filter feeders. When eating large prey, sharks injure them first to bring them under control and then use their teeth to bite and grind their prey. 

Sharks are known to bite. However, it is incorrect to believe that they are biting machines. Some of their species, such as Great White Sharks, are aggressive, yet they don’t attack and bite to be aggressive. Shark attacks on people are quite uncommon. Nonetheless, they do bite through their prey to satisfy their hunger.

There are another shark species known as the “living fossils,” the goblin sharks. These sharks, which belong to the mitsukurina family, are the only surviving family member and have evolved during the early cretaceous period, dating back 125 million years. They are one of the strangest-looking sharks.

Sharks, like fishes and cetaceans, have fins. These fins stabilize the shark and help it stay afloat in the water as well as move forward. Without their fins, sharks won’t be able to glide through water or hunt for their potential prey. Therefore, fins play a crucial role in facilitating the shark’s movement.

Among their many other amazing adaptations, sharks are best known for unique tongues. The mouths of sharks contain structures resembling tongues. Unfortunately, they are not true tongues. These are bony projections in sharks’ mouths, also known as basihyals. They look like tongues while being not tongues at all. This is probably because a shark’s taste buds aren’t located on its tongue.
