Great white sharks are a shark species, whereas orcas (also known as killer whales) are from the dolphin family. Each of these animals has a distinct coloration which makes it easy for a commoner to differentiate between them. Although these animals vary greatly, there are several points of comparison between them.

Killer whales are essentially toothed whales, whereas blue whales belong to the baleen whale family. As such, while killer whales can bite into their prey and tear it apart, blue whales can only use their baleen plate to sift their food through water. Besides, killer whales and blue whales have different coloration too.

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. 

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, 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.

Baby sharks, like grown up sharks, have a full set of teeth. They become independent creatures as soon as they are born and swim away from their mothers. As a result, they are left to fend for themselves and their sharp teeth come in handy.

Goblin sharks are not dangerous at all, especially to human beings. Over the years, there have been rare reports of goblin sharks attacking humans unprovoked but this species is pretty harmless in general. It prefers to swim in deep waters and remains aloof for the most part.
