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.
On its website, SeaWorld, which owns all but one of the captive orcas in the U.S., states that the average life expectancy of southern and northern resident killer whales is about 29 years for females and 17 years for males..
