Where are sperm whales found?
How big is a male sperm whale?

Sperm whales are the biggest animals on Earth that have teeth. They are carnivores, which means they eat meat. Although sperm whales can be found in all oceans, they prefer the waters with high squid populations, which are their main diet. A sperm whale can eat up to 1,500 kg of food each day. Sperm whales are big animals. The male can grow up to18 meters long and weigh up to 54,000kg while the females are a bit smaller with a length of 12 meters and a weight of 17,000kg. A female sperm whale gives birth to one calf every five to seven years after a gestation period of fourteen to nineteen months. The life span of sperm whales can be up to sixty or seventy years. It is interesting to know that they also have the largest brain of mammals. Sperm whale populations are at risk due to hunting and their accidental entrapment in fishing nets.

EXAMPLE WRITING
Dolphins are not fish, they are mammals that live in the water. Dolphins are among the most intelligent on Earth. Although they can be found in all oceans in the world, dolphins prefer coastal waters and bays. The size of dolphins varies greatly. The smallest dolphin is just about 50kg in weight and 1,2 meters in length while the largest one can weigh up to 8,200 kg and is 10 meters long. Dolphins are carnivores and they eat mostly fish. A female dolphin gives birth to one calf every two years after a gestation period of eleven to twelve months. A dolphin can normally live from twenty-five to sixty-five years and some species of dolphins can even live longer. Dolphin populations at risk due to the population of their habitat and accidental entrapment in fishing nets.`
