Task1: (Work in pairs) Read the description of the sperm whale
and then complete the table that follow:
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.`
