The pygmy right whale which has the scientific name Caperea Marginata is an specimen which is very difficult to find, so there isn´t enough information about them. Their blue and grayish shades,in conjunction with their stylized figure, can also be mentioned as distinctive features of this specie. In addition, since blue whales belong to the group of baleen whales, they have many of the characteristics habits of this group, as is the case of their diet, which is based mostly on krill, one the smallest marine species. Note that given their size, there are not natural predators that represent a real danger for them. In this sense, since 1966 the International relevant authorities, have taken all the necessary measures to preserve the existence of the planet’s largest animal, since humans are the main threat for them. However they are considered as an endangered species, since they are very persecuted for hunting purposes, to a point which almost causes their extinction. The blue whales, can be found in almost all the oceans of the planet. These facts make of them the most prominent-baleen whale species (see article the biggest whales of the world These specimens outstand for being the world’s biggest animals, since they can reach even 30 meters in length, and 173 tons in weight. The group of Baleen Whales, comprises 15 species that are distributed at the same time in two genera, and these are t the best-known: Blue Whale, Now, let´s start our videos session, so you will know more about baleen whales In addition to the afore mentioned, another of the morphological adaptations of this specie, is their distinctive thick layer of skin and a layer of fat beneath it which maintain the body´s temperature even when they are in cold waters. This is the main reason why some species of baleen whales, have developed huge capacities to submerge into bigger depths than other species of whales. On the other hand, as in the case of other whales, they also have two spiracles to carry out their breathing process. ![]() Their maxillary beard can be mentioned as their most highlighting characteristic, and its main functions is to filter food from water. There are evidences that indicate that they can move at more than 37 kilometers per hour. Given their physical characteristics, the baleen whales usually reach high speeds when they are swimming. However they aren´t considered as agile and dynamics, as the pinnipeds. Moreover, the baleen whales are also characterized by having fins and a tail, which were developed throughout the evolution process of their main limbs in order to get adapted to the conditions of the aquatic environment. ![]() In the same way, there may be variat ions between the specimens of this group, especially regarding their outer characteristics, as is the case of their shape, weight and length.
