The killer whale has many breeding habits that are known to researchers that suggest that the killer whale may be more like humans than previously expected. The newborn calves of an orca whale population have been observed by scientists at various times during the year. This suggests that orca whales have no particular breeding pattern that stops them from wanting to reproduce at any time during the year. The orca whale in its natural habitat becomes sexually active from the years of 10-18 and the female orca whales can reproduce when they reach around 16 feet in length. The males must reach about 20 feet in length before they can reproduce in contrast with the females. The killer whales has been studied long term and these studies have produced more information about the gestation period of the orca whale which can last anywhere from 13 to 17 months. In addition to this the calve of a typical orca whale can be up to 8 feet in length when born.
Other interesting facts about killer whales include their ability to reproduce offspring into their 40's. This is an aspect of the life of killer whales that make many scientists compare them to human life. The orca whale is found all over the world with this breeding pattern and the females can also have a calf every two years though many choose not to have their calves in such rapid succession. Most female killer whales have a calf once every 3-5 years. If you are interested in killer whales and their mating patterns and rituals then it may be a good idea to see them for yourself at an aquarium close to where you live. Aquariums can be great places to learn about all manners of marine life including the killer whale.
