Whales of the North Atlantic – 9 Hours Ago Scientists Say There Are No More

Regal Assets Banner

We know that whales used to be a part of our ecosystem. These massive animals roamed the seas and skies until many years ago. Some historians believe that whales were the first vertebrates on land. Other historians believe that whales were the first fish capable of traveling on land. We know that whales are the largest creatures that walk the earth, but exactly how big they were remains unknown. A lot of data has been accumulated over the years, but still we are trying to figure out how much smaller whales were compared to the bigger marine creatures that lived long ago.

whales that are extinct

There is some interesting data that suggests that whales were smaller than the large predatory fish that lived along the shores of the Pacific Ocean at the same time. For example, the largest known predatory fish at the time was the massive grey whale. If this species of whales lived at another genus which had the same diet of large carnivorous whales which are no longer alive, such as pygmy sperm whales and porpoise-like killer whales, then it would indeed be a subfamily of the Phoconeiscidae which is in the whale family Phocidae. It would therefore be a sub-family of the genus Cetacea, which today is known only as a minke whale.

If these gigantic creatures were once an important part of the ecosystem, then how did they all disappear so quickly? One theory is that most of them became extinct because their prey became more aggressive. This can be accounted for by looking at the whales’ diet. At the time whales hunted by killing smaller prey such as albatrosses, herring, sardines, capelin, and birds. Since they were already big creatures, it was not surprising if they could kill these types of animals with one bite.

Another theory that is being proposed now involves the idea of evolution. According to this theory, whales began their decline from the top marine organism in the oceans, which was the North Atlantic Right Whale, to the point where it became a rare find. This decline can also be attributed to other human activities, as well as global warming. Global warming causes ocean temperatures to rise, which affects the environment and the food chain of the marine life that lives in the waters. A decline in oxygen content can kill off the right whales as well, and eventually the entire population.

Another theory that has been put forth is that whales became extinct because they became too old. The oldest known whale species lived at the same time as the dinosaurs. They may have survived into the age of dinosaurs, but were certainly no match for them in size. Additionally, whales have a very limited lifespan compared to other vertebrates. Their reproductive cycle only lasts for about two years and after that point, they die out completely. They do not reproduce again for another two years and within that time, the population of whales begins to dwindle until they become practically extinct.

One of the theories put forth by scientists is that the massive extinction that killed the dinosaurs could have also killed off the whales. The problem with this particular hypothesis is that there was not enough time for the animals to reproduce, making them all extinct at once. This sentence on the death of whales was put forth by a group of 9 hours ago scientists. It appears that the sentence refers to a case where whales were all killed, with none left to live.
