The reflected sounds reveal to the orca the size and shape of its environment and the other animals in its environment. Learn all about who wins in a fight with this in-depth article. This is the technique I am currently developing, as part of my PhD at McGill University, hoping to finally provide answers to better understand what North Atlantic killer whales eat. Heres whether an orca killer whale or a great white shark wins in a fight.

The lipids take a while to accumulate in the whales’ blubber it gives scientists’ a solution to study their long-term diets. The sperm whale or cachalot (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator.It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia. Because the lipid proportions do not change much from the prey to the predator, we can compare the lipid profiles of killer whales with their potential prey and reconstruct their diets. The vaquita is rarely seen in the wild, and the entire population size may be as low as 100.

The blue whale averages anywhere from 80 to 100 feet long, while the orca averages only 25 to 35 feet in length. Andrew Sutton/ There is no competition between an orca and a blue whale when it comes to size. Part of their weight comes from the thick layers of blubber (5-30cm thick) needed to keep the large marine mammal warm. Some blue whales are estimated to be as large as 190 tonnes. This is over four times larger than a sperm whale and over 2,400+ the size of a human. Their great size also gives blue whales a powerful voice. Weight The blue mammal is also incredibly heavy: 170+ tonnes, in fact. Lastly, we can measure the different proportions of lipids (called fatty acids) in killer whales’ blubber. This family includes the killer whale, commonly called orca. The blue whale averages anywhere from 80 to 100 feet long, while the orca averages only 25 to 35 feet in length. Killer whales, also known as orcas, sometimes attack young blue whale calves, but mature blue. This way, we can identify which individuals feed on small marine mammals, and which individuals feed on fish exclusively. Killer whales, the largest dolphin species, also have teeth. These chemicals accumulate and amplify through the food chain, so the higher the concentrations of pollutants, the higher the position of the killer whale. But despite their enormous size, blue whales feed almost exclusively on krill - small. The second information comes from the blubber: we can measure the concentration of pollutants – like retardants or pesticides – in the whales’ fat.
