5th reflective Journal

Sperm whales are often spotted in groups (called pods) of some 15 to 20 animals. Pods include females and their young, while males may roam solo or move from group to group. Females and calves remain in tropical or subtropical waters all year long, and apparently practice communal childcare. Males migrate to higher latitudes, alone or in groups, and head back towards the equator to breed. Driven by their tale fluke, approximately 16 feet (5 meters) from tip to tip, they can cruise the oceans at around 23 miles (37 kilometers) per hour.

These popular leviathans are vocal and emit a series of "clangs" that may be used for communication or for echolocation. Animals that use echolocation emit sounds that travel underwater until they encounter objects, then bounce back to their senders—revealing the location, size, and shape of their target.

Sperm whales were mainstays of whaling's 18th and 19th century heyday. A mythical albino sperm whale was immortalized in Herman Melville's Moby Dick, though Ahab's nemesis was apparently based on a real animal whalers called Mocha Dick. The animals were targeted for oil and ambergris, a substance that forms around squid beaks in a whale's stomach. Ambergris was (and remains) a very valuable substance once used in perfumes.

Despite large population drops due to whaling, sperm whales are still fairly numerous.

Finally finished my work of Sperm whale and Dhole information.

Sperm whales are known to dive as deep as 3,280 feet (1,000 meters) in search of squid to eat. These giant mammals must hold their breath for up to 90 minutes on such dives.

These toothed whales eat thousands of pounds of fish and squid—about one ton (907 kg) per day.

Sperm whales' heads are filled with a mysterious substance called spermaceti. Scientists have yet to understand its function, but believe it may help the animal regulate its buoyancy.

Dholes inhabit forested areas in South East Asia. They can be found in India (where the largest population of Dholes is found), Bangladesh, Sumatra, Java, Myanmar, Tibet and China.

I have explained all the information about Dhole, and now i am going to do the information about Sperm whale.

Sperm whales are easily recognized by their massive heads and prominent rounded foreheads. They have the largest brain of any creature known to have lived on Earth. Their heads also hold large quantities of a substance called spermaceti.

Whalers once believed that the oily fluid was sperm, but scientists still do not understand the function of spermaceti. One common theory is that the fluid—which hardens to wax when cold—helps the whale alter its buoyancy so it can dive deep and rise again.

In India, Dholes prey on Sambar, Chital, swamp deer, nilgai, blackbuck, gaur, wild pigs, ground dwelling birds and rodents. Chital make up the majority of their diet. In Siberia their diet includes Reindeer and in Tibet they are known to prey on sheep. Dholes hunt in packs and cooperate to catch their prey which they kill by eviscerating it in a similar way to how African Wild Dogs kill their prey.

Dholes have a gestation period of approximately 63 days. The young are born in an underground den with up to ten pups in a litter (although 4 is more usual). When giving birth and raising young, several females in the pack may share a single den. Once the pups are weaned, the entire pack will regurgitate food for the young. When the pack goes out hunting, some members will remain behind to guard the young pups in the den. The pups remain in and around the den for the first ten weeks of their lives, and by seven months old they are able to join the rest of the pack on hunts. The young are mature at 1 year old.

1st reflective journal

sorry for the very late post as my computer has been down for some days. so to start off, my group members and i have been researching for information of a whale called the Sperm whale, and a fox called Dhole.

i'm going to give more information about the Dhole first.

The Dhole or Asiatic Wild Dog (Cuon alpinus) is about the size of a border collie (12-18 kg), but looks quite different. The coat is usually a rusty red colour, but varies regionally from sandy yellow to dark grey, usually it has a black bushy tail and white patches on its chest, paws and belly, its ears are rounded, and its hooded amber eyes portray an intelligent nature. The Dhole is a highly social and cooperative animal, living in organised packs of around 10 individuals. Groups often contain more males than females, with usually just one breeding female. Occasionally, large groups of over 40 dogs have been seen, possibly arising from the temporary fusion of neighbouring packs.

About Pola Bear...
Polar bear live only in the northern Arctic where they spend most of their time in ice floes. They are the larger land meat-eater in the world and the largest in the bear family. They are well suited to the cold Arctic ice and snow.

2nd Reflective Journal
The indentification of the polar bear:

Height:Average adult male 8.5ft(2.6m)
Average adult female 6.5ft(2m)

Weight:Average adult male 900Ibs.
Average adult female 500Ibs.

Colour:off-white fur with black nose,eyes and mouth.

3rd Reflective Journal
Polar bear will eat seal flest or even their type of pola bear.

4th reflective Journal
Pola bear is closely related to the brown bear. Their family type is Ursidae.

5th reflective journal
I like pola bear as it is cute..
