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.
A fascinating characteristic of orca is that they have the longest gestation period of any whale, averaging 16 to 18 months. This may seem surprising as killer whales are a relatively small whale compared to the big baleen whales, who have gestation periods lasting 11 to 12 months.
