Harbour Porpoise
| The harbour porpoise is the topic of my research
report. The harbour porpoise is a marine mammal. The scientific name for the harbour
porpoise is phocoena phocoena. The status of this animal in Canada is threatened. In my
report I have threats, appearance, habitat, food, and interesting facts of the harbour
porpoise. This report will help you learn more and protect my marine mammal. The harbour porpoise has some very interesting appearances. The harbour porpoise is one of the smallest whales. It measures about 1.6 meters and weighs an astonishing 50 kilograms. It has pronounced beak. The dorsal fin is small, dark and slightly rounded. It is a marine mammal and it is smaller than other dolphins. The harbour porpoise has some very interesting habitats. It inhabits bays, oceanic canals and harbours. It is found off Canada's east coast. This porpoise can also be found in Davis Strait and Baffin Bay. They prefer water temperature 5-16 degrees Celsius. They like change of current and turbulence. The harbour porpoise has two foods in the ocean that I found. It likes to eat zoo plankton and schooling fish (schools of fish). I wonder if it eats schooling fish for breakfast, lunch and dinner and for desert zoo plankton. The harbour porpoise can get killed easily by several different threats. It's main predator is the shark. It can also get killed by humans trying to hunt them for money. It could get caught in fisherman's nests. The habitat is destroyed by water pollution and by the time it found a new habitat it would be going through so much pollution that it would get sick and die. The harbour porpoise has some very interesting facts. It has been protected by the Canada's fisheries Act since 1982. WWF (World Wildlife Foundation) puts transmitter on to track the harbour porpoise. Life expectancy is 13 years but now only 8 years. Females give birth to 1 calf a year. It can hurt sharks and even scare them away. The current population is unknown. By Scott
