Omura's Whale Little is known about this whale because was until 2003 that it was thought to be a smaller form of the Bryde's Whale. The description was made public in Nature, a British scientific weekly journal by three Japanese scientist. They determine the existence of the new specimen by DNA analysis. It was later discovered that its closest relative might be the Blue Whale. It is one of the smallest species of rorqual.

Searching for images of this whale I saw a few videos of the whale eating and it was amazing. I never thought this size o f animal could be so fast.

The Bryde's Whale has been a kind of puzzle for scientists because three species use to fall into its category. This is called complex in taxonomy. In other words, three (or maybe four) species of whales were thought to be subspecies, (or just the same species) as the Bryde's whale.

I wonder why not just name all four species the same if they are so closely similar? The devil is in the details. Those little differences that make one species become different from others can be the starting point for a completely new animal in million years. On the other hand, those tiny changes also may be the ones that make the animal adapt better than its relatives and therefore survive the changes of the environment.

So if is similar in appearance, as it seems in the cetaceans, there are movements and changes that are only perceptible in millions of years of evolution.

Can I suppose that the Balaenopteridae family is a young one, therefore many of its members are closely similar? Could be...

Whales are divided into three families. This is the second and biggest: the Balaenopteridae, which contains the biggest animal that ever inhabits the earth. However, we will start with its smallest member but also the fastest: the Mink Whale. This is the most common whale and is probably due to its not being commonly hunted by humans. Its size is too small (about 10m) and does not have enough oil yield, so hunting it is not worth it. Nonetheless, the hunting of this whale has increased.

Its name is confusing because it was first confused and classified wrongly. Its name is derived from the Norwegians who usually refer to any type of small whale as Minkie or Minkies' hval.

The Dwarf Mink Whale was described as a new subspecies not long ago and it is not sure yet if is one. Still has not scientific name. Mink Whale in captivity.

Mink whale has been tried to keep in captivity in Mito Aquarium, in Japan a few times. Most of the specimens died in few weeks while in 1956, the last one was able to scape a net aquarium after 37 days spinning the pool in the same direction.

____ I'm really ignorant of whales and most of this information is new to me. It is very hard to understand the information and translated it into something that I am able to explain. I hope is understood. ____ Thanks for your support. Likes, reblogging, or follows are very much appreciated.
