The O‘ahu individuals were tagged on five different days between October 5 and October 17, while the Hawai‘i individuals were tagged on two different dates (December 10, December 18), thus individuals appear throughout the animation. The animation goes through the end of January 2010. The animation below shows the tracks of five different Pseudorca satellite-tagged off of O‘ahu in October 2009 as well as four individuals tagged off of island of Hawai‘i in December 2009. This animation illustrates both the extended periods that individuals may remain in one area, and the rapid broad-scale movements among the islands that tagged individuals often make. Each step in the animation shows 12 hours of movements. The animation below shows a 52 day track of an adult male Pseudorca from the insular population (HIPc172 in our catalog, an individual previously seen in 2003 off O‘ahu and in 2004 off Hawai‘i Island) satellite tagged in December 2008. Animation produced by Damon Holzer, Northwest Fisheries Science Center. For more information on this work see the publication on movements of satellite-tagged Pseudorca. Lines shown are purely to join consecutive locations for each whale and do not indicate travel routes. The maximum time interval between steps is approximately 12 hours. Each step in the animation is one set of locations obtained within 10 minutes of each other, and the time intervals between steps average about one hour. This animation shows the movements of five individuals over a 10-day period. Two outreach maps were created: one for fishermen and one for naturalists.Īs part of our work to examine movements and stock structure, in July 2008 we satellite tagged seven Pseudorca from the insular population. This information was used to create a map of how frequently boaters and fishermen may encounter insular false killer whales, fitted over the State’s commercial fishing reporting area grid. In this way, we are able to identify areas of high use. Satellite tagging data shown here in a 12 hour switching state model, which displays the satellite tagged false killer whales at noon and midnight. The current population estimate is approximately 160 individuals. This population was listed as Endangered under the Endangered Species Act since 2012 due to significant declines in the population. The Main Hawaiian Island (MHI) insular population is very tightly associated with the islands, remaining within 120 km from shore. This population is estimated to have approximately 600 individuals. Unlike the pelagic population (above), the NWHI population is tightly island-associated, or insular. The Northwestern Hawaiian Island (NWHI) population’s range overlaps with the waters around Kaua‘i and Ni‘ihau. The pelagic population is far ranging as you can see by these satellite tag tracks. The blue line is the EEZ – exclusive economic zone – delineation around the Hawaiian Archipelago, extending 200 miles from land in every direction.

Tagged animals, each from different group encounters, from the pelagic Northwestern Hawaiian Island (NWHI) population.This is inspired from the fact False Killer Whales are so friendly with other dolphin species in real life.There are three populations of false killer whales in Hawaiian waters, based on a combination of association patterns (with each other), genetics, and movements from satellite tagging. It will be larger than its real world derivative, and will also have a supporting ability that can boost other cetaceans. The False Killer Whale is planned in Additional Creatures to focus more on speed and agility rather than power like the Orca or utility like the Narwhal. Mixed pods, while uncommon, are not rare, and they interact in this fashion with numourous dolphin species, not just a few. False Killer Whales are commonly seen interacting with other dolphin species, mostly in the friendly sense. It is, however, much more known for the opposite. It also bears a similar color pallet without the white spots, and occasionally is seen having a similar nature in hunting smaller dolphins. It is a very large dolphin, getting up to 6 meters long. The name of the creature comes from similarities to the Orca. False Killer Whales are mammals confirmed to eventually be added to Additional Creatures 2: Wild ARK.įalse Killers are a large dolphin species found in the modern open ocean.
