Pygmy Orca (Orcinus pygmaeus)

Not to be confused with the Pygmy Killer Whale (Feresa attenuata), the Pygmy Orca is a docile, hand-sized cetacean generally found in sub-tropical waters. Its name stems from the uncanny resemblance to the full-sized Orca (Orcinus orca), known to the Inuits as the Sea Wolf, and more colloquially as the Killer Whale.

Pygmy Orcas, like their larger cousins, congregate in pods of up to 32 for safety. Their communal nature and higher than average intelligence is also evident in their feeding patterns. They work together to herd and swarms of krill into a waiting subset of the pod. Pygmy Orcas are the only toothed whales to actively predate on krill, as it is the only food that will fit into their mouths. Like their larger cousins, Pygmy Orcas employ echolocation to navigate the seas and to find food. Each pod has a designated alpha couple who coordinate feeding and migratory paths. Pods of Pygmy Orcas are often seen coasting in the slipstream of full-sized whales, allowing them to traverse vast distances on minimal energy.

Pygmy Orcas are very familial and mate for life. A couple can produce up to 3 babies per litter, but are only fertile every 3 years. The pups take about 14 months to reach full maturity and size. The adults take turns tending to the pod's nursery, while others hunt. The average lifespan of a Pygmy Orca is about 15 years.

As they are mammals, Pygmy Orcas can live out of the water for brief periods of time, but their skin is delicate in the air and will dry and crack if taken out of the water for too long. They are not large enough to have large stores of blubber, so they live in warmer waters than their namesakes.
