What Makes Killer Whales Shows Interesting
For over one hundred years, whales have fascinated crowds around the world and inspired stories, songs, poems, novels and film. For the last century or so, it has been largely believed that whales are just large lumps of meat; however, recent evidence shows differently. Recent studies show that whales are complex creatures with a complex social structure and diverse lifestyle, which is unlike any other animal in the animal kingdom.
In 2021, a research team led by Dr. Peterenger of the Institute for Marine Research in Hamburg, Germany published a paper in the Journal of Marine Research that described the internal anatomy of the largest known sperm whale. The results of their study showed that the male sperm whale has tenectomies, or areas of skin that form tears during mating that allow the sperm to swim smoothly through the water. Genome sequencing of the six species of orca whales revealed that they have very wide variety of genetic diversity and have evolved over the years into a highly organized group with a very wide distribution in the earth’s ocean. This study strengthens the idea that whales are vertebrates.
Researchers now know that whales are bony fish-whales that are unique to the earth’s oceans. Their teeth are arranged in a complex manner, which allows the animal to bite deeply and inject its tongue in order to extract food from the marine environment. One of the most unique features of whales is their ability to jump long distances through the water. For whales, taking part in an ocean expedition is a social event that is enjoyed by a family whale watching from shore.
It is said that whales have the highest body density of all animals, weighing up to thirty five thousand pounds for the female and up to twenty eight thousand pounds for a male. They also have very sensitive bodies that are highly sensitive to the elements of weather and ocean salinity. When researchers looked at the structure of the whale’s mouth, they noticed that it has many unique features and are made up of two layers. The first layer is made up of soft tissue and the second layer consists of hard bony material. Aside from the unusual appearance of the whales’ body, whales have one of the most stable nervous systems in the animal kingdom and possess excellent hearing, sight and smell.
Although whales and orca are considered to be carnivores, they do eat fish and aquatic plants. In fact, they hunt prey using their highly evolved hunting apparatus called telepathic hearing and sight. Interestingly, whales and orca feed on fish, krill, crustaceans, shrimps and algae during their short lives. The fact that whales and orca are omnivores is a bit confusing as they are believed to be carnivores at birth.
Whales and killer whales differ in several respects. One of the most significant differences is in their physiological and behavioral characteristics. Whales are large, strong and belong to the phylum cetaceans, which includes all modern whales and dolphins. On the other hand, killer whales are very small and belong to the order Orcasmida, which includes sperm whales and hippos.
