The oxygen needs of animals vary. It really depends on their size, activity, adaptations, and several other factors. There are some animals that use oxygen rapidly, and others that can hold their breath for quite sometime. Humans breathe several times a minute. Whales can go for about 15 minutes between breaths. Some Spiders can go more than two days.
