In our last article on Sperm Whale facts we learned about how the creature looks, how it behaves, where it lives etc. We couldn’t (or rather, we didn’t) speak about the animal’s feeding habits and how it navigates in the open oceans. In this article on fascinating Sperm Whale facts, we are going to touch through those facts and at the end, provide some of the most fascinating fun facts about the majestic beast. So, let’s get started…
Fascinating Sperm Whale Facts: 1-5 | Feeding Habits
1. Sperm Whales’ favorite food is squid. They feed on several species of squids that include both the Giant Squid and the Colossal Squid. However, medium-sized squids are the ones that commonly get hunted.
2. Octopuses also become lunch or dinner of Sperm Whales and so do several species of fish including the Demersal Rays.
3. Sperm Whales have the habit of sometimes taking toothfish and sablefish from long lines. The reason why these beasts go after long line fishing operations is that they get easy access to food and can ditch the need for hunting.
4. Sperm Whales are also known to feed on Megamouth Shark. It is a rare shark species that lives in deep-sea and was discovered in the 1970s.
5. The squid beaks that get lodged into the intestines of Sperm Whales often lead to production of ambergris (analogous to pearl production). Sperm Whales usually vomit out such beaks but at times, they may move further down the guts and get stuck in intestines. That’s when a lubricant-like substance is excreted by the intestines to cover up the beak so that it can easily pass out while defecation.
Fascinating Sperm Whale Facts: 6-10 | Hunting and Echolocation
6. Sperm Whales have quite some appetite. They need slightly over 900 kilograms of food in a single day. For this they need to hunt. They are very good hunters.
7. For hunting, they dive deep into the sea or ocean. They will usually dive to the depths of 300 meters to 1,200 meters. However, they can also dive as deep as 2 kilometers in search of food.
8. In such great depths, it is not possible to see. This is the reason why they make use of echolocation for finding prey. They will release a series of sounds called clicks that will allow them to focus on their prey.
9. Sperm Whales are toothed whales. This means they use their teeth to grab and eat the prey. The bottom jaw is where pointed long teeth are visible. The lower jaw is around 18 centimeters to 20 centimeters long.
10. The upper jaw has sockets. The teeth on the lower jaw fit into those sockets. Well, that doesn’t mean that upper jaw of a Sperm Whale doesn’t have any teeth. They have teeth in upper jaw but those teeth never grow out.
