The 1966 International Whaling Commission finally gave Blue Whales protection, although they have only recovered slightly since then. These scars record the number of ovulations (or perhaps pregnancies) for the individual and have been used in the past as an estimator of age. Despite their large size, fin whales suffer from parasitization by several other organisms, most of them small. For further information visit www.aboutcookies.org or www.allaboutcookies.org. In fact, of the five known subspecies of blue whales, members of the Antarctic (Balaenoptera musculus intermedia) populations tend to be even larger than other blue whale subspecies.

There is what looks like a moustache of long bristles on the end of each plate to help it hold the minute prey. Feeding is usually at depths less than 100 m; harpooned animals have dived as deep as 500 m. During the summer feeding season the blue whale gorges itself, consuming an astounding 3,600 kg or more each day. What the team wound up with was the first ever continuous recording of the remoras attaching themselves to a host organism, in this case a blue whale more than 30 times their size. It is thought that in good conditions blue whales can hear each other across distances of up to 1,600km. Baleen refers to 300 to 400 strands of keratin tissue (related to human hair, toenails, and fingernails) that hang down from the upper jaw. After an almost complete absence for over half a century, Antarctic blue whales are returning in numbers to the waters surrounding South Georgia island in the south Atlantic. Life Span: Average 80-90 years. Scientists have discovered that by counting the layers of a deceased whale's waxlike earplugs, they can get a close estimate of the animal's age. They feed almost exclusively on krill, straining huge volumes of ocean water through their baleen plates (which hang from the roof of the mouth and work like a sieve).Some of the biggest individuals may eat up to 6 tons of krill in 1 day.

Intensive hunting in the 1900s by whalers seeking whale oil drove them to the brink of extinction. By counting these layers much like the rings of a tree, researchers can effectively count each year that the whale visited its winter feeding grounds. Despite their massive size, they are victims of many parasitic species. Image courtesy of William Oestreich The researchers described their findings in a new paper in the journal Current Biology . Very little is known about blue whale mating and calving, although a few nursing grounds have been identified, for example in the Gulf of California. Blue whales can grow to a length comparable to that of a Boeing 737. Blue whales and other baleen whales have long plate-like structures in their mouths that they use to filter krill from the water as they swim. The blue whale’s conservation status is often difficult to assess due to limited knowledge of the species’ life history. Currently, there are approximately 10,000-25,000 blue whales in the world’s oceans, representing only 3-11% of the original population size. of food to fill a blue whale's stomach.
