Marine biologist Ari Friedlander and his team have designed a special video camera, which for the first time in history was able to be fixed on the back of one of the most mysterious whales - the southern minke whale. With its help, scientists were able to obtain unique footage from the life of these animals.
The minke whale that lives in Antarctic waters is an understudied animal. It feeds on the same krill as big whales, but does it differently. Loves depths, but maneuvers without fear under the thickness of ice fields. It differs not in strength, but in agility and speed of movement. The main question before the installation of the camera among oceanologists was: do minke whales really have a monstrous appetite, or is this an invention?
The device is held on the animal's back on special suction cups, but can slide along it so as not to be accidentally dropped. Thanks to this, Friedlander's team saw with their own eyes how and how much the minke whale eats. It turned out that it accelerates to 24 km / h (this is under water), takes a huge sip, filters krill out of the water - and all this within just 10 seconds, after which the process is repeated.
Most of the data from the camera on the minke's back is still being processed, but scientists already have something to show the public. And representatives of the fishing sector, who consider minke whales as a commercial species, but have to take into account the distribution of krill in order to maintain a biobalance in the Antarctic region. The voracious minke whale will become an important indicator of the situation in different areas of the southernmost continent.
