Two marine species have been named after Munk. One is "Sirsoe munki", a deep-sea worm. The other is "Mobula munkiana", also known as Munk's devil ray, a small relative of giant manta rays living in huge schools, and with a remarkable ability to leap far out of the water. A 2017 documentary, "Spirit of Discovery (Documentary)", follows Munk in an expedition with the discoverer, his former student Giuseppe Notarbartolo di Sciara, to Cabo Pulmo National Park in Baja Mexico, the place where the species was first found and described.
