Rare Sighting Of Tropical False Killer Whales Off Orange County Coast
They may not be the primary species that pops in your head when you think about dolphins, but they want our assist urgently. The populations appear to be pretty spread out, and are often present in deeper seas which means that we don’t know an awful lot about them. But there’s one inhabitants, who stay in shallower waters off Hawaii, that is well–studied, and lots of what we do know comes from this group. False killer whales are so sociable they’ve even been known to offer meals to human divers.
It often inhabits open oceans and deep-water areas, although it could frequent coastal areas near oceanic islands. Generally, the false killer whale targets a wide selection of squid and fish of various sizes during daylight hours. They sometimes goal giant species of fish, such as mahi-mahi and tuna. A video taken in 2016 near Sydney exhibits a group hunting a juvenile shark. It generally discards the tail, gills, and stomach of captured fish, and pod members have been identified to share food. False killer whale researchers in New Zealand rely closely on sightings stories.
There is little documentation of predators taking false killer whales, although a killer whale attack was observed in New Zealand. At least two false killer whales in Hawaii carry scars from large shark bites, indicating that large sharks target the species from time to time1,9. The species has been involved in several mass strandings throughout its range13-15. Captivity – false killer whales are held in tanks and face the danger of being snatched from their households to be sold to the leisure industry. You’ll recognise these dolphins fairly simply due to their lengthy, slender, black or darkish gray bodies, a slender pointed head with no beak and a outstanding bulbous forehead, or ‘melon’. They have long, slim S-formed flippers that make them look as if they’ve elbows and a tall, tapered dorsal fin.
Playful and social, these dolphins enjoy hanging out with different species, together with bottlenose dolphins. They are susceptible to beaching in giant teams – maybe as a result of the noise we humans make underwater messes with their navigation. Sound travels much farther in water than gentle, and cetaceans commonly use sound rather than imaginative and prescient to speak with one another and find meals. Just as cetaceans pay attention for each other and for his or her prey, we are able to hearken to their sounds to locate teams of whales and dolphins. False killer whales can dive for as much as 18 minutes and swim at excessive speeds to seize prey at depths of 300 to 500 meters.
