The Rice whale is also known as the Gulf of Mexico whale, is a relatively newly discovered whale. Until 2021, it was thought that this whale was a subpopulation of the Brydes whale, however it is actually genetically distinct.
Growing up to 12.65m and weighing between 13.8-27.2 metric tonnes, it is found in the north-east of the gulf of Mexico. unfortunately it is on the brink of extinction. The deep-water horizon oil spill killed around 20% of the whales of this species.
While it has not been observed, the killer whale actively hunts in the area, and has regularly killed sperm whales. Brydes whales have also been targeted, so it seems impossible that rice whales are not targeted.
Around 100 of these whales exist, which is very close to extinction.
