Why are Blue Whales Endangered?

1. Whaling

Blue whales have probably become endangered due to their large size, which manages to draw the attention of humans towards them. Whale hunting is believed to be the main reason why there are only few individuals from the species left. Whaling much diminished the number of whales left in the world’s bodies of water. The size of these whales made them extremely attractive to hunters.

2. Natural Causes

Blue whales usually live in cold environments, so they can easily be injured by ice. Even though blue whales shock with their impressive dimensions, they can simply become victims of other inhabitants of the ocean. Blue whales can be hunted by killer whales.

3. Fishing Equipment

Fishing equipment may also cause many whale deaths. Blue whales can easily entangle in fishing gear. As they can get seriously injured, fishing equipment is believed to be one of the main causes which has lead to the death of many blue whales.

How Can You Help?

1. Dispose of pollutants and hazardous wastes properly.

2. Join organizations dedicated to protecting whales. Donate time or money.

How they Interact

The biggest threat to the Balaenoptera Musculus from the ocean is the killer whale, Oricinius Orca. Also interacts with krill.


An adult blue whale eats up to 40 million krill in a day, therefore, they manage the krill population in their environment. Some barnacles dot on the back of the blue whale. Also lamprey eels attach themselves to the blue whale with its mouth for a ride and a bite of the blue whale's blubber to eat.
