What does the Kilimanjaro, the tallest mountain on African soil, have to do with corals in the ocean? Well, it turns out that there are channels of cool water that developed millions of years ago under the Mt Kilimanjaro, and these end in the Indian ocean off the coast of Mombasa. With the recent warming of the oceans, this cool water meets the ocean right on the coast to create a sort of marine sanctuary for corals, dolphins, and even species taught to be extinct.

The coral sanctuary is a wildlife hotspot, teeming with spinner dolphins and boasting rare species, including prehistoric fish and dugongs. Researchers believe its location in a cool spot in the ocean is helping to protect it and the surrounding marine life from the harmful effects of the climate crisis.
[Tim] McClanahan, the lead scientist for the Wildlife Conservation Society, who lives and works in Mombasa, Kenya, said he had an “epiphany” when he realised why the reef was so rich in wildlife. The coastline has the highest density of dolphins in east Africa, and coelacanths, fish once believed extinct, swim in its deep waters. “I thought ‘why are all the animals here?’ And I realised it was because of Kilimanjaro,” he said.
The coral refuge, which stretches from Shimoni, 50 miles south of Mombasa, in Kenya to Dar es Salaam in Tanzania, is fed by cool water from deep channels formed thousands of years ago by glacial runoff from Mt Kilimanjaro and the Usambara mountains.
