Malcolm Roy Clarke (1930–2013) was a British teuthologist who made an important contribution to marine science in theAzores archipelago (Portugal). Malcolm started doing research in the Azores from 1980s onward, settling for residency in 2000after retirement (in 1987). He kept publishing on Azorean cephalopods collaborating in 20% of the peer reviewed works focus-ing on two main areas: dietary studies; and the ecology of cephalopods on seamounts. Since his first visit in 1981, he wasinvolved in the description of the dietary ecology of several cetaceans, seabirds, and large pelagic and deep-water fish.Using his own data, Malcolm revised the association of cephalopods with seamounts, updating and enlarging the differentcephalopod groups according to species behaviour and ecology. Malcolm taught several students working in the Azores oncephalopods and beak identification, lecturing the Third International Workshop in Faial (2007). He empowered the recentlyestablished research community, by providing important contacts with foreign institutes and informal advice. He collaboratedin the regional cetacean stranding network (RACA) and was an active member of the advisory board of the journalArquipelago—Life and Marine Sciences. But the scientific role of Malcolm Clarke in the Azores went beyond his academicactivities. In the last 10 years Malcolm and Dot Clarke dedicated themselves to building and running a museum on PicoIsland, showing the biology of the sperm whale and its interaction with squid; a cultural and touristic legacy for future gen-erations to enjoy.
