A common question asked about this species is, “where do blue whales migrate?” Despite their grand size, exact blue whale migration routes are not completely known. With new data, they now propose the same for all Antarctic killer whales and possibly all whales that migrate to the tropics.Coauthors on the paper include scientists from NOAA Fisheries; SeaLife Response, Rehabilitation, and Research; and the Italian National Institute for Environmental Protection and Research.This B2 type killer whale was tagged in the Antarctic Peninsula area and tracked for 113 days. The older and pregnant whales migrate first while the immature whales bring up the rear.Amid this migration back to the tropics, they eat virtually nothing for at least 4 months and live on their bodies reserves. The question is why—is it to find food, or to give birth? During the warm season, whales migrate to cold waters where food is abundant. That would reduce regeneration of skin cells and halt the normal sloughing of skin.Migrating to warmer water would allow whales to revive their skin metabolism and molt in an environment that does not sap their body heat.

The Summer: Southern right whales migrate to colder food-rich waters near Antarctica for the summer, but to where exactly is not known.

Whales in Australian waters.

Researchers also photographed newborn killer whale calves in Antarctica, indicating the whales don’t need to migrate to warmer waters to give birth. ".The annual (versus continuous) molt cycle of the beluga was long thought to be unique among cetaceans. Some species migrate as stated below: How far do whales travel? been estimated to be as high as 110 years.Blue whales mainly feed on krill, which are small shrimp-like organisms. When whales shed their skin, they also shed the diatoms.Recent studies have found that high concentrations of diatoms on the skin of Antarctic killer whales may also accumulate potentially harmful bacteria.“Basically, the feeding is so good in productive Antarctic waters that the relatively small, warm-blooded killer whale has evolved a remarkable migration behavior. Most migrations were fast, non-stop, and largely straight north and back. Wintering grounds are off the coast of southern California, Baja California, Taiwan, Japan and Korea.Blue whales migrate often, which means they move from place to place many times throughout their lives.

In addition to the blue whales massive size it is also one of the loudest animals in existence. Scientists have never agreed on why. small animals swimming in the water, which the whale eats.Blue whales can usually be seen traveling alone or in groups made up of 2 to 4 individuals. These whales swim at speeds of For the best experience, please use a modern browser such as Chrome, Firefox, or Edge.First suggested for killer whales, skin molt may drive long-distance migration for all whales that forage in cold waters.Threatened California Central Valley steelhead will benefit from a new Habitat Conservation Plan for the Calaveras River. A baby blue whale averages 23 feet (7 meters) long and 4,400 pounds

They suggest that larger whales that migrate to the tropics to molt may have begun giving birth in those same warmer waters. When the weather becomes colder, the food start to scarce and whales migrate to warmer water for mating and breeding. Marine Mammal Science 15: 1228-1245. Islands. Most migrations were fast, non-stop, and largely straight north and back. 2016. Marine Ecology Progress Series 162: 287-299. In the winter, this population group may be seen in the waters off of Cape Cod, Massachusetts, and on rare occasions another population group may possibly be seen in the Gulf of Mexico and the Caribbean.

This enables it to exploit these resources and still maintain healthy skin function,” said John Durban, coauthor of the research, formerly with the science center and now a senior scientist at SEA Inc.In another example, beluga whales in the Arctic are known for gathering in summer in river estuaries.
