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.
Killer whales can live as long as 90 years. Like all cetaceans, this species depends heavily on underwater sound for feeding and communication, using clicks, whistles, and pulsed calls. They are very social, and many orcas live with their mothers for their entire lives.
