Sperm Whale is one of the most amazing creatures we have on our planet. This particular animal holds several records (apart from being the largest creature on Earth – the crown that goes to Blue Whale) that might come as a serious shock to anyone. So, let us learn some really interesting Sperm Whale facts that we think you might like and even need for your school project. Let’s begin…
Sperm Whale Classification
Before we start with the list of Sperm Whale facts, let us quickly take a look at the scientific classification of animal.
Now, let’s get started…
Sperm Whale Facts: 1-5 | Description
1. Wondering how to figure out which whale is Sperm Whale? Look at the head. It has a really large head and its forehead is rounded. However, the overall head is a bit squared. In fact, its head makes up nearly 1/3rd of it full body length.
2. Talking of the large head, did you know that Sperm Whales have the largest brain in whole of animal kingdom? Yes, their brain weighs an amazing 17 pounds. In comparison, human brain weighs a meager 3 pounds.
3. Did you know that our brain (human brain) occupies just 2% of our body weight? Compared to this, the brain of a Sperm Whale occupies only 0.2% of its body weight. So, whose weight is really big? Think, think!
4. The Sperm Whale is a type of a Cetacean whale species. Other cetaceans include dolphins, other whales (actually all whales), porpoises etc. Did you know that some cetaceans are toothed while others are not? Sperm Whales are toothed cetaceans. This means they have teeth. Not all whales have teeth (such as the Blue Whale).
5. Though not as big as Blue Whales, the Sperm Whales are pretty large. The males are anywhere between 11 meters to 20 meters in length. The females on the other hand are a little smaller with a size of anywhere between 8.2 meters to 17 meters.

6. Sperm Whales are also quite heavy. Adult Sperm Whales can weigh anywhere between 25 tonnes to 45 tonnes.
7. What about the babies? The Sperm Whale babies are call calves (plural). A calf at birth can be as big as 4 meters in length and can be as heavy as up to 500 kilograms.
8. All cetaceans are known for having a blowhole. Sperm Whales are no different. They too have one. However, instead of being located on the top of the head, the blowhole of a Sperm Whale is located to the left of its head.
9. It is this unique location of the blowhole that allows quick identification of Sperm Whale pretty easy even from a distance. They will have a low and bushy spout that is forward projecting and slightly towards the left.
10. As far as a Sperm Whale’s body is concerned, towards the tail on the body, a large hump is visible on the back. That hump is then followed by a series of smaller bumps.
