Unlike the living sperm whale, which has no functional teeth, the ancient Livyatan melvillei, with its 36 cm. teeth feeds on other whales and bigger predators.
Have you ever heard of floating gold? We'll apparently, in the beaches in Europe, they do exist. But not in a shiny, glittery form, instead they look like a rock which smells, too. It's a stone secreted by sperm whales and are used in making perfumes. It is called "whale vomit" and it is extremely rare. It is considered valuable because a block of it can cost up to $70,000. But authorities fear that if people decided to harvest whale's vomit, it might further worsen the population drop of the endangered sperm whales.
According to the study published in the journal PeerJ, researchers discovered that their findings are consistent with the hypothesis that the structure of sperm whale's forehead evolved to be used as a massive battering ram during male-to-male competition.
In an important campaign to bring in more research money for the unique population of belugas in the St. Lawrence, whose waters are downstream from the industrialized Great Lakes, sponsors are being found as part of the opportunity to "Adopt a Beluga." Wouldn't you like a blubbery, chirpy small whale?
Researchers recently discovered harmful algae toxins in Alaskan whales, walruses, sea lions, seals, porpoises and sea otters. Their findings represent a staggering northward expansion of such toxins, although (for what it is worth) they have not yet reached concentrations harmful to human health.
Researchers have identified why so many sperm whales washed up on beaches in the North Sea. It turns out they were hunting for squid in shallow waters.
A juvenile humpback whale was spotted this week in Boston Harbor near a Hyatt Regency. Was it seeking upscale lodging?
A dozen giant sperm whales have found themselves stranded along the Dutch island of Texel and the German islands of Wangerooge and Helgoland this year. Experts say many made made wrong turns toward the coast after becoming disoriented.
Scientists from McGill University in Montreal, Canada, recently learned a little more about the elusive marine creatures known as narwhals by focussing on newborns.
Humpback whales are spending some extra time up north in Alaska this season. Experts say the whales are slow to arrive at breeding grounds in Hawaii because of possible food competition or El Niño disruptions.
Marine animals are altering their diets and natural habitat range as a result of climate change. For instance, melting sea ice is opening new waters to humpback and fin whales, which could lead to increased food competition among the areas' native species.
While some animals use color to express their mood, Beluga whales blow bubbles toshow how they are feeling. Using their mouths and blowholes, the large-headed whales may produce one of four differently-shaped bubbles to signal feelings of aggression, fear, or playfulness, for example.
Whales are adversely impacted by the sounds ships make under the water. The combination of a vehicle's speed and its propeller count play a large role in noise disturbance.
More than 17,000 marine species, including whales, sharks, rays and fish, remain threatened due to a lack of marine protected areas.
