A deep-sea beaked whale washed up on a Plymouth, Massachusetts, beach. The carcass is so rare that it has made marine experts quite confused and they are trying to know the exact species of it and how did it reach the shore.

The whale was found on a Plymouth beach lying on the rocks. The female whale is 17-foot in length and weighs almost 1 ton. It is quite rare as it has a long slim snout and dark purplish skin. The toothed whale is quite similar to a dolphin, but bigger in size.

The New England Aquarium staff said, "They are so rarely seen that New England Aquarium biologists have been conferring to determine the exact species, which they believe to be a Sowerby's beaked whale. Aquarium staff last handled a beaked whale in 2006 in Duxbury".

The biologists said that the carcass has not rotten and is in good condition. During the first inspection, the whale did not show any scars or signs that it has been entangled and also there were no trauma signs from a vessel strike.

Sowerby whales are found hundreds of miles away from shore. Therefore, it is very uncommon to find such type of mammal on the beach. Majorly, they spend their lifetime in deep water, so biologists do not know much about them.

These whales are known to dive deep and remain in water for long periods. For now, it is not known as what has caused the death and investigations will be taking place.
