Humpback Whales -- Gorgeous Ocean Mammals

Introduction :

Whales are Mammals that live their entire lives in the vast oceans that cover the earth.

As they are Mammals, they give birth to young ones just like Humans do. Their Life -Span is also similar to Humans.

Humpback Whales have bodies that are well geared to move through vast oceans. Their Bodies are constructed in such a way that helps them to survive in oceans where the currents are fairly strong.

Humpback Whales have extremely strong fins that help them to move through vast amounts of water in the Pacific Ocean and Atlantic Ocean.

Since, Humpback Whales are Mammals they need to come to the surface of the water regularly to breathe.

Eating and Breeding Habits :

The average Humpback Whale feeds mostly on Krill and on small fish like Herring. They eat about 500 Kilos of small fish and krill every day in order to maintain body weight.

North Pacific Humpback Whales spend their time breeding in the coastal waters around Hawaii.

Humpback Whales start arriving in the waters around Hawaii from early October and their numbers rapidly rise by February and March.

Humpback Whales that are young mothers usually have their first calf when they are between 8-10 years old. Calves that are just born are around 10-15 Feet in Length.

Humpback Whales that live and breed in the Pacific Ocean are "Pseudo Opera Tenors of the Pacific" because of their seeming sorrowful songs they sing to each other during the breeding cycle.

Conclusion :

It seems like Humpback Whale Populations are generally doing well but yet there are areas of concern.

As, their populations increase there is the possibility of accidents because of collision with Humans on the High Seas namely in the form of deadly accidents with Merchant Navy Ships and getting caught in Fishing Nets of Deep Sea Trawlers.

The need of the Hour is to have a strict "No Fishing Zone" in the Pacific Ocean where Humpback Whales live and breed.
