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.
Living in a pod allows females to better protect their calves from orca attacks. Once sperm whales reach maturity, there are no predators except man capable of killing them, and their lifespan in the wild is approximately 70 years. Calves are born every three to six years and can take 10 years to mature.
