Spiraling Senses

Roughly the length of an olive, decapods are made up of 20 or more body segments. Among the most eye-catching of these segments is a coiled antenna stemming from its head, which could easily be mistaken for a tiny spring. WHOI biologist Nancy Copley and colleagues collected these shrimp-like creatures, along with other zooplankton, off the coast of southern Africa using MOCNESS sampling nets to assess plankton biodiversity as part of the Census for Marine Zookplankton project.
