It's back! :D Expand this post to see a summary of past OotD's!Organism of the Day
The Orcinus orca
, commonly known as killer whales
, is the largest species of the oceanic dolphin family. They are apex predators with no natural predators, and can be found in all the oceans of the world, including polar regions.
Orcas are have an incredibly diverse diet. Although some feed exclusively on fish, many orca groups have been found to feed on other sources, such as other oceanic mammals and birds. Some orca packs have even been observed hunting blue whales and other large baleen whales. Studies have also shown that orcas may be very intelligent creatures, and definitely sport complex social systems.
Today there are ongoing discussions over whether orcas can still be classified as an individual species. Due to varying appearance and behavioural patterns, biologists have suggested that the orca species should in fact be split up into new species, or at least subspecies. The results of these discussions may become apparent over the next few years.About Organism of the Day
