We just HAD to share these EPIC pics taken by local photographer Jesse Brown while he accompanied our interns on an Ocean Safari whale-watching trip yesterday! The group saw a single Humpback Whale and then encountered THREE Southern Right mother-calf pairs, some of which were very relaxed and approached the boat (as allowed under boat-based whale-watching regulations).
Of particular interest were three observations:
1) A gorgeous calf speckled with white. Most southern right whales are essentially black, with variable white pigmentation on the belly. But there is a well-documented polymorphism in skin pigmentation. Researchers have described several patterns, including black, white-blaze, grey-blaze, grey-and-white-blaze and grey-morph/partially albinistic whales and Jesse's pics are consistent with what the southern right whale literature calls a partial grey morph. Interestingly, genetic research suggests that almost all partial grey-morph calves are females!
2) Several pics show the mother has her mouth substantially open, with a large section of the baleen rack exposed. That is exactly the morphology you'd expect to see during filter-feeding. Southern Right whales do feed in South African waters. A 2023 University of Pretoria study documented feeding by southern right whales in the Southern Benguela Upwelling System, with Calanoides copepods identified as an important prey item. Interestingly, that study found both shallow/surface feeding and deeper feeding.
3) A calf playing in the waves, but REALLY close to shore, which they do quite often - in fact, studies show that across the cape coastal nursery area, most mother-calf pairs are found within 900 m of the shore, and are often seen right behind, or in some cases (like this) in them!
A massive thanks to Ocean Safaris for taking our research interns out each week, enabling them to learn more about these incredible animals! If you are in Plett, now's the time - get on a boat with Ocean Safaris_Plettenberg Bay_Western Cape!
