What Do Sperm Whales Eat?

The Sperm whale is the deepest diving known animal in the world.

This marine mammal can dive to depths in excess of 6 ,000 ft. underwater although most of the time their dives are usually no more than 2, 600 ft.

While some information has been uncovered regarding the diets of these amazing hunters their hunting methods have not been well researched due to the deep dives these whales make when hunting for food.

Sperm whales are known to eat giant and colossal squid, octopus, cephalopods, cuddle fish and a variety of other fish.

Their primary diet however consists mainly of squid and since they eat food that lives in fairly deep water they do not have to worry about their food being captured by fishermen or other mammals.

Most of what is known about their squid diet has been studied from the contents found inside the sperm whales stomach.

While researchers haven’t really been able to witness any battles between a sperm whale and colossal squid (which can measure in at over 45 ft and weigh more than 1, 000 pounds) the markings found on the sperm whales head indicate struggles they’ve had while trying to consume this species of squid.

In comparison to the colossal squid the sperm whale can grow to lengths in excess of 50 ft. and weight more than 45 tons.

Sperm whales can be found swimming throughout all of the worlds major oceans and are the largest of the toothed whale suborder.

Unfortunately it is estimated that whalers killed as many as 1,000,000 sperm whales over the last few centuries which is now causing an imbalance in the oceans ecosystem and affecting our ozone layer.

Rough estimates suggest that there are now anywhere between 200,000 – 1, 500, 000 sperm whales left.

Studies have shown that the nutrients in sperm whale poop helps stimulate the growth of phytoplankton which pulls carbon from the air providing a cleaner and healthier breathing environment for all animals.

It is estimated that as much as 400,000 tonnes of carbon are extracted from the air due to these whales each year!

If all of these estimates are accurate than the additional carbon that could have been extracted from the air by the sperm whales that were killed would have amounted to a lot more clean air and a much more balanced and healthy oceanic ecosystem.
