It is actually rare for a marine mammal to “drown,” as they won’t inhale underwater; but they do suffocate from a lack of air. Being born underwater can cause problems for newborn whale and dolphin calves. It is the touch of air on the skin which triggers that first, crucial breath.

How long do whales sleep for?

The whales were found to spend seven percent of their day in these vertical sleeping positions near the surface of the water, where they napped from 10 to 15 minutes. Researchers suggested at the time that they might be one of the world’s least sleep-dependent animals.

Can whales die of old age?

Cetaceans can simply die from old age. Their lifespan ranges from a few decades for harbour porpoises to over 200 years in case of bowhead whales. They can also die from predation from killer whales, polar bears or from sharks.

Do whales drink water?

Despite a few exceptions, pinnipeds and cetaceans do not usually drink. In most cases, water is supplied by the metabolism of prey proteins (metabolic water) and the oxidation of fat (drinking water). In cetaceans, these waters may be sufficient to maintain a water balance in the body.

Do spiders fart?

Since the stercoral sac contains bacteria, which helps break down the spider’s food, it seems likely that gas is produced during this process, and therefore there is certainly the possibility that spiders do fart.
