Übersetzung im Kontext von „false killer whale“ in Englisch-Deutsch von Reverso Context. Some orca populations show differences in their genetic make-up and behaviour that make them quite distinct from each other. The population continues to struggle and has declined over 10 percent since With more than 10 years of funding, collaboration, and ingenuity we have taken substantial and important steps to aid Southern Resident killer whale recovery. Communication may also occur using Killer Wale gestures such as light touches, Bingo Gewinnwahrscheinlichkeit out of the water, lunging, charging, lob-tailing or spy-hopping. April 23, There is evidence that killer whale speciation may also be occurring in the North Pacific, where as many Spieleseiten three genetically divergent groups exist with significantly different dispersal patterns, calls, social Kleine Spiele Online, and diets.
The largest males attain a length of more than 10 metres Males also have proportionally larger appendages, with flippers up to 2 metres 6.
Flipper length among females is 11—13 percent of body length. The dorsal fin of older males is very tall up to 1. The skull is a metre or more in length and holds the largest brain of all the dolphins, averaging 5.
The muscles that close the mouth are enormous, and within the jaws is a set of more than 40 interlocking curved teeth. Most of the teeth are large, measuring about 10 cm 4 inches long and 4 cm 1.
The killer whale has a patchy distribution in all oceans, from the polar ice caps to the Equator , where large prey such as tuna , salmon , and seals are abundant.
Other food sources are squids , sea lions , penguins , whales , and porpoises. In the North Pacific several populations live along the Alaskan coast, in the intracoastal waterways of British Columbia and Washington , and off the coast of Baja California.
Killer whales live in small groups, usually called pods, that number fewer than 40 individuals each. Resident pods and transient pods have been differentiated within the populations of British Columbia and Washington.
Sound production and diet differ between them, with resident pods that is, those that inhabit Puget Sound and nearby coastal waters eating fish primarily salmon and transients that is, those that range over larger areas of coastal waters eating other cetaceans, seabirds, and seals.
Echolocation is used by killer whales in feeding and communication. Known to be highly intelligent, killer whales are among the few nonhuman animals to be able to recognize themselves in a mirror.
Killer whales are also one of the small number of species—along with human beings Homo sapiens , short-finned pilot whales Globicephala macrorhynchus , false killer whales Pseudorca crassidens , belugas Delphinapterus leucas , and narwhals Monodon monoceros —that experience menopause that is, the stoppage of ovulation prior to the end of their natural lives.
The circumstances under which menopause evolved in killer whales are a matter of debate, but it may have emerged in response to increases in the mortality of offspring from older generations during times when mothers and their daughters bred simultaneously.
Some scientists argue that younger females in the pod tend to focus on the success of their own offspring and may be more competitive for food resources than older females see competition.
Killer whale pods are extended families that have matriarchal hierarchies see also dominance hierarchy. Read the recovery plan for Southern Resident killer whales.
Rather than convening a recovery team for Southern Resident killer whales, we used an open public process to engage as many interested stakeholder groups and individuals as possible and work with a variety of partners to implement the action in the plan.
Those areas may be designated as critical habitat through a rulemaking process. The designation of an area as critical habitat does not create a closed area, marine protected area, refuge, wilderness reserve, preservation, or other conservation area; nor does the designation affect land ownership.
Federal agencies that undertake, fund, or permit activities that may affect these designated critical habitat areas are required to consult with NOAA Fisheries to ensure that their actions do not adversely modify or destroy designated critical habitat.
We designated this habitat because it contains three features essential to the conservation of Southern Residents:. Learn more about the proposed revisions to critical habitat for Southern Resident killer whales.
Learn more about critical habitat for Southern Resident killer whales. Chinook salmon stocks are currently lower than historic levels, putting Southern Resident killer whales at risk for decreased reproductive rates and increased mortality rates.
Our scientists have also organized workshops and panels to better understand the effects of salmon fisheries on Southern Resident killer whales.

NOAA Fisheries and Washington State have also taken steps to reduce threats to killer whales by regulating how close a vessel may get to the species in Washington State waters.
This reduces disturbance to the animals and the potential for negative interactions. These regulations make it illegal to:.
Learn more about vessel regulation in Washington State. We work with many partners to promote the Be Whale Wise campaign to educate boaters on the regulations and viewing guidelines in place to protect killer whales and all marine mammals.
We also encourage land-based whale watching, as part of the Whale Trail, as a way to enjoy viewing without any effects.
We work with volunteer networks in all coastal states to respond to marine mammal strandings. When stranded animals are found dead, our scientists work to understand and investigate the cause of death.
Although the cause often remains unknown, scientists can sometimes identify strandings due to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise.
Some strandings can serve as indicators of ocean health, giving insight into larger environmental issues that can have implications for human health and welfare.
Get information on active and past UMEs. The spill was strongly correlated with the deaths of most of the AT1 Transient pod.
There have been no observed births to the AT1 stock of the North Pacific transient killer whale population since , and the population has steadily declined to 7 individuals.
In , NOAA Fisheries reviewed a petition concerning the possibility that the AT1 killer whale group of Prince William Sound may be genetically distinct from other killer whales in Alaska, and may be depleted.
We designated critical habitat for Southern Residents in and a recovery plan was completed in In , we issued a month finding on a petition to revise critical habitat for Southern Residents.
In December , we completed a 5-year status review of Southern Resident killer whales. NOAA Fisheries scientists are leading the effort to answer key questions about the risk factors potentially affecting killer whales, with a special focus on the Southern Resident population.
Our scientists and collaborators collected length and width data for killer whales using both vessel-based laser photogrammetry and aerial photography from unmanned aerial systems hexacopters.
This research aims to provide a comparative assessment of nutritional status to guide management of these two protected populations. Learn more about our photogrammetry research PDF, 2 pages.
Together with our partners, we track location data from satellite tags deployed on whales. This research helps determine the winter migration, feeding habits, and range of Southern Residents.
Learn more about Southern Resident killer whale tagging. NOAA Fisheries' researchers and collaborators use digital acoustic recording tags, recording the sounds they receive and the sounds they produce, to examine sound exposure, sound use, and behavior of Southern Residents in their summer habitat.
This research helps address threats like vessel disturbance, noise exposure, and effects on feeding. Learn more about digital acoustic recording tags.
Scientists study the transfer of contaminants from mother to offspring through blood during gestation and through milk during lactation.
This research helps us understand whether young whales are at greater risk than adults for negative health effects from contaminants.
Learn more about pollutant transfer. Our scientists study the amount of energy dolphins need to produce loud sounds. Because dolphins and killer whales are related, research on dolphins is also applicable to killer whales.
This research addresses the biological costs of environmental noise, as animals must produce louder sounds when human activities generate noise underwater.

In most cases, the bond between juvenile and mother will eventually weaken, and the young orca will go its own way, but in some pods, the juvenile may stay with the pod it was born into its entire life.
Orcas are highly intelligent, social mammals that have long been a part of marine park entertainment, performing shows for audiences.
However, it's become increasingly clear that orcas do not thrive in captivity. They have evolved to swim up to 40 miles a day, foraging for food and exercising.
They dive to feet, several times a day, every day. Whether they're born in the wild or in captivity, all orcas born have the same innate drive to swim far and dive deep.
Artificial enclosures in captivity cannon offer that kind of range to orcas, contributing to boredom and stress. Orcas have been seen to develop stereotypies, also known as zoochosis—repetitive patterns of activity that have no obvious function, which range from self-mutilation to rocking and swaying.
Usually related to stress and inappropriate habitats, stereotypic behavior has been documented in orcas in scientific research since the late s.Über die Fortpflanzung des Schwertwals ist nur wenig bekannt.
