37 whales are found in South Africa 's waters. And there are only 78 species of whales and dolphins world wide. In South Africa whales and dolphins can be divided into two main types, baleen whales (including the Southern Right Whale, Humpback and Bryde's Whale) and toothed whales (including the Sperm Whale, Killer Whale, Beaked Whales, dolphins and porpoises). Baleen whales use horny plates in the mouths (baleen or whalebone) to strain food (minute plankton or krill) from the water, while the toothed whales generally feed on fish or squid.
Length: 12 - 14,6 m
Weight: 12 000 - 20 000 kg
Cruising Speed: 4 - 16 knob
Blow: Tall and thin about 4 metres high
Status: insufficiently known
Length: 14.6 - 15.2m
Weight: 30 000 - 40 000 kg
Cruising Speed: 4 knots
Blow: Pear-shaped and upright, about 3m high
Status: Endangered
Breeding biology: Both mating and birthing takes place to the north
of South Africa in warm tropical coastal waters. Gestation is approximately
11,5 months and peak birthing occurs in August. Lactation (suckling) takes
place approximately 11 months.
Length: 14 - 18 m
Weight: average 41 000 kg
Cruising speed: 2-3 knots
Blow: V-shaped and between 4 - 5 metres high
Status: Vulnerable
Breeding biology: This involves several males trying to mate with a
single female. The males have the largest testes of any mammal and fight
their reproductive battles with shear quantities of sperm. The female
prevents mating by lying on her back, but when she turns over to breathe, a
male will take the opportunity to cover her. Gestation is approximately 12
months and lactation probably occurs from between 6 to 12 months.
