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.
Minke whales live 40 to 50 years. Sperm whales live about 75 years. This is the traditional believing about the lifespan of whales, however, there is new evidence that comes from the fact that a fragment of an old bomb manufactured between 1879 and 1885 was found lodged in a old whale shoulder.
