BELUGA WHALES DELPHINAPTERUS LEUCAS ALSO NAMED AS THE SEA CANARY

HUMAN IMPACTS ON THE SPECIES

Pollution by chemicals and cancer causing agents at the estuaries from the industries has led to a decline in the Beluga whale population

New oil and gas centres for resources has also led to some contamination in the waters thereby declining the population.

BIOLOGY

Belugas are white in colour

Belugas are marine warm blooded mammals and breathe air through the blow holes

Life cycle is about 25- 30 years

Size of minimum 5 metres(16 feet) in length

Female Belugas give birth to one calf in three years

When the calf is born, it is about 4-5 feet long and weighs about 45- 64 kg. The calves are blue to brownish red for the first year of the life. During the second year they turn grey to blue and by the end of six years they turn white. The baby is nurtured with its mother's fat- laden milk which is about 28% fat. It is weaned in about 12-24 months and they reach maturity by 7-9 years.  

Gestation period is 14- 15 months.

BIOME

Arctic Tundra

It is the coldest biome charcterized by very low temperatures and are located in the far north of Greenland, Alaska, Canada, Europe and Russia

HABITAT

Clean Air

Found in the Sub-Arctic seas

Lives in cold Frigid waters but some population of the Belugas migrate to the south to warmer waters in summer

Lives at temperatures below Zero degree celcius.

STATUS

Threatened

Special concerns: some population of the Belugas are critically endangered

Beluga Whales are threatened by pollution (DDT, PCB's etc) in estuary waters that they frequently breed in.
