(See ETYFish); humani: In honor of the late Brett A. Human (d. 2011), Australian marine biologist, Western Australian Museum (Perth), for “important contributions to shark taxonomy in South Africa and Oman in the western Indian Ocean region, and who is sorely missed by his colleagues”. (See ETYFish).
