Although we see them catching mahi-mahi a lot (it is the most frequently recorded prey species in our study), often the glimpses are quick or at a distance. False killer whales can form large pods of up to 500 individuals and break off into smaller pods of 15 25. People have spotted false killer whales further north and south but typically remain in deep-ocean, tropical waters. We’ve had four encounters this project (in the first 8 days – today is day 9 and the boat is out now), but in the four encounters, we had a lot of feeding on December 3rd (11 different predation events), but 3 the second day, and none the last two days. False killer whales are deep-diving dolphins and can be found at a maximum depth of 15,000 ft (4,700 m). Pseudorca (False Killer Whale) is a genus of mammals in the family Delphinidae. This is the fourth project we’ve done based on this island (2012, 2017, and 2018), and each project has just been 2-3 weeks, and we have had great success here. Robin Baird added, “Over the years, we’ve satellite-tagged quite a few individuals so have been able to identify “hot spots,” and one of them is off the southwest side of Lāna‘i, the island where we are currently based. The researchers recorded what they say on their website were “several predation events on mahi-mahi.

The population around the main Hawaiian Islands is small (the most recent estimate, from 2015, is 167 individuals), and most of those spend most of their time on the windward sides of the islands (the trade winds blow from the east to the west, and almost all the small boat research in Hawaii is on the west sides of the islands where it is relatively calm.” We’ve had some years with a couple of months of fieldwork where we may only see them once or twice in a year (and some years we’ve never found them despite a month or more of fieldwork).

They can grow to be 20 feet and dive more than 3,000 feet. It can find rare items using its knowledge of the castle and keen. The animal got its name because the head is similarly shaped to that of a killer whale. The false killer whale, marked with an X, that you befriended in the sunken Valka Castle. The animal is called a false killer whale but is actually a species of dolphin. It was first described in 1846 as a species of porpoise based on a skull, which was revised when the first carcasses were observed in 1861. It is found in oceans worldwide but mainly in tropical regions.

The false killer whale ( Pseudorca crassidens) is a species of oceanic dolphin that is the only extant representative of the genus Pseudorca.
The water in Kina's pool is nearly green, a clear indicator of excess nitrogen in the water." Kina lives in the dark green tanks in the bottom right. "She says in the comparison of Kina's pool to the one they use with guests located above it, the one above is much cleaner as there is no green coloring to it due to a filtration system or routine cleaning.
"One of the members of Empty The Tanks Hawaii is an environmental scientist with an emphasis in clean water and water quality testing," Parra said. Both past drone footage and recent photos show that Kina's tank is filthy - much dirtier than the other "on display" tanks at the marine park. In other words, Kina would be suffering in the sunlight, and probably getting burned.īesides the lack of shade, there are also concerns about cleanliness. "This is incorrect - light penetrates to the bottom of shallow captive display tanks, which are also usually painted reflective colors." "The industry claims that cetaceans can avoid the sun by going below the surface of the water, as they do in the wild," Naomi Rose, a marine biologist with AWI, told The Dodo.
