They also have the largest brain out of any animal known to exist. Female sperm whales on the other hand tend to be much smaller growing to lengths of 34 — 38 ft. The head of the whale contains an organ known as the spermaceti organ, hence its name, which was once believed to produce sperm, but has since been proven to serve another unknown use. Some researchers believe that the spermaceti organ assists the whale with buoyancy by allowing the whale to adjust the fluid balance and consistency within its head; after all the sperm whale is the deepest diving animal in the cetacean family. In comparison to the rest of its large block shaped head the lower jaw is long, narrow and filled with cone-shaped teeth that fit into sockets in the upper jaw. The teeth however do not appear to be necessary for biting or consuming prey as sperm whales that do not possess teeth appear to be able to consume their prey with little or no issues when compared to toothed sperm whales.
How Did the Sperm Whale Get Its Name?
Why Are Whales Important?
I believe what I am trying to do will make a difference to the marine environment and protect one of the most magnificent animals in the world. I will achieve this by stopping illegal whale hunting. I aim to create a protest around the world by using social media website such as facebook. Read more about the pledge. Read more about the petition.
Whales as ecosystem engineers
Biological and research studies in whale behavior, echolocation , language , intelligence, environmental impact and various other topics have helped scientists learn so much about the whale species and their impact on this world. By observing how they thrive and survive in the ocean we have learned a great deal about their social structure and how they communicate with one another. Depending on the whales species some marine mammals are known to spend the majority of their lives together and will hunt with one another and protect each other from harm. In addition to forming highly developed relationships and societies with one another whales also display a high level of intelligence and self recognition a characteristic that is found in only a few animal species.
When the International Whaling Commission meets in Morocco next week to discuss lifting the moratorium on commercial whaling, delegates might pause to consider an unexpected fact: the faeces of sperm whales is helping to save the planet. Australian researchers have found that the iron-rich faeces of sperm whales living in the Southern Ocean boosts the growth of phytoplankton, marine plants which suck in carbon dioxide from the atmosphere. They estimate that the whales are responsible for removing , tonnes of carbon each year, twice as much as they contribute through respiration. According to the scientists, based at Adelaide's Flinders University, they would be disposing of 10 times as much carbon were it not for commercial whaling. Their faeces is useful because it is emitted in liquid form close to the surface of the ocean, where phytoplankton is found, according to the study, published in the journal Proceedings of the Royal Society B: Biological Sciences.
