Orcas, or killer whales, are highly social and intelligent whales found in every ocean, but most densely in the Southern Ocean.
Language: English Location: United States Restricted Mode: Off History Help These orcas prefer to live in open waters of the Southern Ocean, feeding mostly on minke whales. Type C killer whales are known as Ross Sea killer whales, a dwarf species that is the smallest of the three known Antarctic types of killer whale. The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth.It derives its name from the British explorer James Ross who visited this area in 1841. Campbell Island - Macquarie Island - Ross Sea - Peter I Island - Antarctic Peninsula & Polar Circle | The most spectacular Antarctic journey ever! "In Antarctic waters, there are five different types of killer whales, with Type C being the smallest, growing up to 6.1 metres in comparison to Type A males who can grow up to almost 10 metres long," Ms Wellard said. Males reach around six meters (19.7 feet) in length. Lead author PhD candidate Rebecca Wellard, from Curtin's Centre for Marine Science and Technology (CMST), said the remoteness of the Ross Sea can make it difficult to monitor and record the movements of killer whales, but it is essential to better understand their behaviour and acoustic repertoire.

Compilation of killer whale images into catalogues enables researchers to follow individual orcas in time and space, making estimations of their total population size.

The researchers believe that Type B and C killer whales are genetically similar, because their lineage diverged from other orcas around 150,000 years ago – just a moment in evolutionary terms.
