Whales+-+Yicheng

= How many species of whales are found in the world and how many of these are found in Antarctica and what are their names? Where is their habitat located within Antarctica? =

Do they have any natural predators?
==== Choose three (3) species of whales and in detail discuss the similarities and differences between them. ====

=Minke whale=

=Size and weight= ==== The Minke whale are one of the smallest species of whales. An average male Minke whale is 6.9m and a female is 7.4m. The maximum length for a female is 9.1 to 10.7m and 8.8 to 9.8 for a male. The average weigh is about 4-5t and the maximum weigh is about 10t. ==== = Color =

The  Antarctic Minke whale is black on top and white on the belly
= Age =

They live up to 30-50 years in some cases they can live up to 60 years of age.
=Diet=

Minke whales normally swim 3-16 mph but can go up to 18-21 mph when in danger, the normal feeding speed is 1-6 mph
=Population Numbers= ====It is estimated that there are about almost 800 000 Minke whales worldwide  ====

They either travel by themself or in a small group of 2-3
=Reproduction=

The newborn calf swins to the surface for its first breath.
The weight of the newborn calf is about 454kg and the length is about 2.8 m. =Predators= The natural predators of the Minke whales is killer whale

=How Minke whales survive in Antarctica= The Minke whales has a thick layer of blubber to keep them warm in the freezing oceans of Antarctica

Killer Whale
=Diet= Killer whale feed on fish and other marine mammals such as sea lions, seals, walruses and large whales. They use a series of high pitched clicks to stun their prey =Colour= Killer whales are black on the back and white on the belly =Population= There are about 50,00 killer whales =Age= Male killer whales can live up to 60 years, while female killer can live up to 90 years old.

=Size and weight= An adult killer whale is about 5-9 m and the weight of an adult killer whale is 2.6-9 t baby killer whales weigh 181 kg and 1-2 m long. =Reproduction= Killer whales breed in Winter to early Spring it is usually performed in warn waters Calves are born weighting 181 kg and 1-2 m long.The calf is able to swim after 30 minutes of being born. =Speed= Killer whales can travel up to 34mph =Predators= There are no natural predators in Antarctica that hunt Killer whales =How Killer whales survive in Antarctica= Killer whales has a thick layer of blubber that helps them to survive in Antarctica

=Humpback whale= =Size and weight= An average length of an adult humpback whale is 10-15 m and 23-30 t the size of a newborn humpback whale is 3-4 m and 1-2 t =Color= The color of the Humpback whales is black on top and white and bottom.

=Diet= Humpback whale eats krills and small fish =Population Numbers= Around 18 000 - 20 000 =Age= It is estimated that humpback whales live for around 40 years

=Reproduction= Reproduction takes place in warmer waters the cold Antarctic waters are not suitable for reproduction calves are nursed until they are a year old.

=Predator= Humpback whales natural predator is killer whales

=How Humpback whales survive in Antarctica= Humpback whales has a thick layer of blubber to keep them warm in Antarctica
