Whales of Ponta
Between the months of July & October we welcome the majestic humpback whale migration were we observe these graceful beings moving between their Antarctic summer feeding grounds and winter breeding grounds closer to the equator.
During this time we combined whale watching with our dolphin experiences.
Research suggests the humpback whale migration is highly structured; females with nursing calves tend to leave first, followed by immatures of both sexes, then the mature males and resting females and lastly females in late pregnancy start the treck.
These departures tend to last around a month. On departing breeding grounds, first off are newly pregnant and resting females, followed by the immatures, mature males and lastly females with newborns. Reference: P.Best
Southern Rights are a rare and exciting visitor to our shores, after their near demise from whaling during which time they were reduced from estimates of 60 000 to only 300 (60 breeding females) in 1920 (IWC, 2001; Jackson et al., 2008; Tormosov et al., 1998).
Although only a few sightings have been had of this species it provides evidence that southern right whales are using the coastal waters of Mozambique again.
Did you know whales also have a fingerprint.
For humpback whales it's the back of their fluke(tail) and dorsal fins, for southern rights its the callosities found on the head!
Humpback Whale
(Megaptera novaeangliae)
The Humpback whale is a baleen whale, meaning that they have no teeth, rather a series of baleen plates with fine hairs that they use to filter the water for the likes of krill, plankton and small fish. They consume vast numbers of small organisms by vacuum-cleaning the ocean. The Humpback Whale has a short and squat dorsal fin and ventral pleats that run from the lower jaw to belly. They are dark on top with varying shades white on the belly, tail and flippers. Knob like tubicals can be found on and around the head, chin and jaw.
SIZE: 10m = 14,9 tonnes
DISTRIBUTION: Occurs throughout the Southern African Subregion
BALEEN: 300 pairs of plates
DIET: Krill, shrimp like crustaceans; small fish (1 - 1,2 tons p/day)
LONGEVITY: ± 45 to 50 years
GESTATION: ± 12 months
MATURITY: ± 13m in length
CONSERVATION STATUS
Red List (ICUN): Least concern
Southern Right Whale
(Eubalaena australis)
The Southern Right Whale received its name as it was the ‘right’ whale to hunt during whaling. They are distinguishable by having a broad back and no dorsal fin, they have callosities on their heads (which are used for identification proposes) and a large arching mouth that starts above the eye. These whales have a reputation for being particularly curious towards humans!
Although only a few sightings have been had of this species it provides evidence that southern right whales are using the coastal waters of Mozambique again.
SIZE: 10,78 = 16,34 tonnes
DISTRIBUTION: South of 20º S
TEETH: ± 37 pairs
DIET: Krill, copepods & small crustacea
LONGEVITY: ±50 to 70
GESTATION: ± 12 to 13 months
MATURITY: ± 14m in length
CONSERVATION STATUS
Red List (ICUN): Endangered
During our whale watching encountours, data is captured and this is contributed to HappyWhale which allow us to track the movement of whales that have been re-sighted.
