Candida albicans is the most commonly isolated species, and can cause infections (candidiasis or thrush) in humans and other animals. In winemaking, some species of Candida can potentially spoil wines.
Killer whales have no natural predators (they are the top predators of the oceans) and can live to about 50-80 years old. Killer whales have been hunted by humans but not with enthusiasm as it takes 21 killer whales to produce the same amount of oil as 1 sperm whale.
A beluga whale calf is born dark grey, with sometimes a bluish or brownish tinge that gets lighter with age. It turns pure white between 5 to 12 years. The adult beluga whale sometimes has a yellowish tinge, caused by a layer of diatoms growing on it, although this colouration is lost during summer moulting â an unusual event for cetaceans.
