[121] They can be trained in captivity and are often described as intelligent,[122][123] although defining and measuring "intelligence" is difficult in a species whose environment and behavioural strategies are very different from those of humans. [12], They are sometimes referred to as "blackfish", a name also used for other whale species. According to observations in several regions, all male and female pod members participate in the care of the young.

Orca Pod (of 5) - Orcinus orca The killer whale (Orcinus orca), commonly referred to as the orca whale or orca, and less commonly as the bla . [152], Another conservation concern was made public in September 2008 when the Canadian government decided it was not necessary to enforce further protections (including the Species at Risk Act in place to protect endangered animals along with their habitats) for orcas aside from the laws already in place. The sound originated from a U.S. Navy frigate 12 miles (19 kilometres) distant, Balcomb said. Orcas (killer whales) . weaning a toddler cold turkey; abc polish newspaper .

The inspiration for the white whale of Moby Dick, sperm whales have the largest heads, biggest brains, and make the loudest sound of any animal on Earth, Region: [142] Orcas are unique among cetaceans, as their caudal sections elongate with age, making their heads relatively shorter.

Preliminary research indicates offshore orcas have group-specific dialects unlike those of residents and transients. Females can often breed until age 40, followed by a rapid decrease in fertility. How much sperm does a whale release? The amount of sperm produced by a whale depends on the size of the whale's testicles as well as the type of whale.
