While many ocean lovers can easily identify the iconic sperm whale, the charismatic humpback and the wily orca, not all are familiar with the bowhead. According to scientists, this colossal year-round Arctic dweller may live plus years. The overall length of the bowhead is long enough to stretch across a four-lane highway with plenty of room on either side. Any bio of the bowhead would not be complete without mentioning its weight, which ranges from tons , and its 1.
With an estimated population of approximately 10,, the bowhead whale is listed as endangered under the Endangered Species Act and depleted under the Marine Mammal Protection Act. Still, researchers have been able to give us a pretty good idea of how long some species of whales do live.
Scientists and researchers have researched the life expectancy of various whale species and have estimated that some whales can live longer than humans. One study concluded that some bowhead whales live around years, and at least one living male bowhead whale has been estimated to be nearly years old.
Some of these factors are as follows:. Habitat — The habitat that a whale, dolphin, or porpoise lives in can have a strong impact on their lifespan. Animals that live in highly commercial areas, for example, are at a greater risk of being struck by a boat, having to deal with pollution, being separated by family and friends, and dealing with increased stress due to a consistently noisy and obtrusive environment.
Diet — The types of food a whale consumes and its ability to find adequate food sources is also important for its survival. Is the food they eat healthy or contaminated, is it abundant or sparse, and is it the best type of food for them?
In certain locations, whales may also face competition for food resources from a fisher in heavily commercialized areas. Lifestyle — The type of lifestyle a whale lives in can assist with increasing or decreasing their age. For example, whales that live in environments where there are more threats from predators may be on alert and face more stress. Species that are naturally social but have been separated from family and friends may become depressed or agitated, leading to isolation and a decreased capacity to communicate with other whales.
The more endangered a particular species is, the more difficult it is for them to find social groups to interact with or mate with. If you have a question about the weird and wild animal world, tweet me , leave me a note or photo in the comments below, or find me on Facebook.
