First five questions: 1. How old do sperm whales live. 2. How long are the males and females in length. 3. How much do the sperm whales weigh. 4. How much do sperm whales eat. 5. Where do sperm whales live. 6. What makes the sperm whales so disireable in hunting. The brain of the Sperm Whale is the largest and heaviest of all animals (weighing on average 7 kg in a grown male). Males are typically 30-50% longer (16-18m) than females (12-14m) and weigh about twice as much (50,000kg vs 25,000kg). At birth both males and females are about 4m in length and 1,000kg in weight. Nursing takes place for two to three years. In males puberty lasts for about ten years between the ages of about 10 and 20. Males continue to grow into their 30s and 40s and only reach their full size when about 50 years old. Sperm Whales live for up to 80 years. Sperm Whales are one of the deepest-diving mammals in the world. They are believed to be able to dive up to 3000 metres in depth and 2 hours in duration to the ocean floor. More typical dives are around 400 metres in depth and 30-45 minutes' duration. They feed on several species, in particular giant squid, octopuses, and demersal rays. The white scars often seen on the bodies of Sperm Whales are believed to be caused by squid. Sperm Whales are prodigious feeders and eat around 3% of their body weight per day. Sperm whales use echolocation to catch their prey in the dark oceanic depths. Mothers also use it it keep track of their young calf when they are diving to hunt; a calf cannot dive very deeply because it has to breathe much more frequently than the mother does. males go in bacholars and females are in pods. sperm whales live all over the world besides the polar seas. there main sorse of food is giant squid. sperm whales are killed for ambergris that they get from eating the giant squids that they eat. but they don't have tobe killed because the ambergris get cough up and washs ashore. sperm whales got their name by the spermaceti inside their heads. sperm whales are on the indangered list. The Sperm Whale is exceptional for its very large head, particularly in males, which is typically one-third of its length. Females give birth once every four to six years and the gestation period is at least 12 months and possibly as long as 18 months with the calf being born tail first near the surface of the water. The newborn instinctively swims to the surface within 10 seconds for its first breath; it is helped by its mother. Within 30 minutes of its birth the baby whale can swim. The newborn calf is about 13 feet (4 m) long and weighs about 1 ton (0.9 tonnes). Nursing takes place for two to three years. In males puberty lasts for about ten years between the ages of about 10 and 20. Males continue to grow into their 30s and 40s and only reach their full size when about 50 years old. The sperm whale is born without teeth, which do not begin to grow until it reaches sexual maturity. The largest teeth are 11 inches long. The sperm whale can dive 560 feet per minute; it ascends to the surface at 460 feet per minute. When the whale expels air after a deep dive, the noise it makes can be heard half a mile away. man has hunted sperm whales for centuries. A sperm whale heart alone weighs 400 pounds (180 kg). there is only one million sperm whales left in the world before whaleing their was 2.4 million sperm whales in the world. sperm whales only preditor is human the killer whale won't even go near the sperm whale because of it's lower jaw. sperm whale are like a family when one whale is hurt other come to help. sperm whales comunicate by clicking and moaning. The Sperm Whale's enormous head and distinctive shape, have led many to describe it as the archetypal whale.

Follow up questions: 1. How many sperm whales are in the world. 2. how long are they pregnet. 3. how long does it take them to get to their full length. 4. do they have leaders of the pods. 5. how long has the sperm whales been hunted. 6. how do their bodys keep moving. 7. do sperm whales have any preditors. 8. how do sperm whale comunicate.
