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.
Whale shark females produce eggs, but the young hatch inside of the mother instead of in the water like most fish. Then, the female gives birth to about 300 live young. Many never make it to maturity, though. Whale sharks have a long childhood. At the age of 25, the offspring are ready to have their own young. They may live 100 to 150 years.
