What do Apollon sharks need to live?

Apollo Sharks need to be housed in a tightly covered aquarium of at least 125 gallon capacity that has plenty of swimming area, high levels of dissolved oxygen, and a good deal of water movement. Their tank should have a gravel or rocky substrate with a background of aquatic plants and some minimal driftwood or bogwood decorations.

Why are great white sharks endangered?

There are multiple reasons why great white sharks are endangered. Bycatching is the accidental killing of great whites when fishing for other fishes. Great whites become entangled and even choked in fishing lines and nets. They are often mistaken as sea bass and halibut and are mistakenly caught from the ocean.

Is the whale shark an endangered species?

The whale shark is listed as an endangered species by the International Union for Conservation of Nature (IUCN). In the IUCN classification system, the status of a particular species can be ranging from Least Concern to Extinct.

What is the most endangered shark in the world?
