Sperm Whale Research Paper

Improved Essays
The colossal sperm whale is the largest of the toothed whales along with a most odd looking lump. That's simply because its head is a third as heavy and big as its tapering body. The huge front end contains the largest of all animal brains along with a huge sac of oil called spermaceti. Its blow-hole is situated on the tip of its head about the left-hand side. This gives the whale a distinctive 45-degree angled blow. The adult sperm whale's bottom jaw is narrow and lined on each side with 20-25 15cm-long teeth. Females have smaller and fewer teeth - sometimes none.

The lower jaw looks flimsy compared to the upper jaw, which sticks out beyond it. But it is strong enough to deter sharks, snap whalers' rowing boats in half and to make short work of giant squid - the whale's prime prey. To discover squid sperm whales must dive into deep water. This species is discovered in all the oceans from the world even though only solitary bulls venture into polar waters. The basis of sperm whale society is the herd of females and young. Calves remain with their mother feeding and growing in warm waters such as the Caribbean.

By this time its l3-20m long - much bigger than a female. At particular times from the year mature bulls head for the tropics, occasionally migrating several thousand kilometres in search of females. The sperm whale has two titchy cousins. The pygmy sperm whale, up to 4m long, seems to live in oceanic waters while the dwarf sperm whale, less than 3m lengthy, inhabits waters from the continental

    “A Possible Break in One of Evolution’s Biggest Mysteries” by Peter Brannen is a sublime piece of writing and he does very well at expressing how whale evolution is seen today and the lengths that scientists are going to improve their understanding. While “12 Examples of Evolution Happening Today” is an enjoyable read and a good beginning to show the different kinds of adaptations and evolution changes that are happening to various species, it does not completely explain each example and does not include outside sources or citations for the data used. Brannen’s article is exceedingly more comprehensive in the topic of whale evolution, and is altogether a more authentic article than Brodwin’s…
