The histology of putative light organs in the parapodia of five species of Tomopteris (pelagic annelids) is examined and compared using light, epifluorescence and scanning electron microscopy. The structural homology of rosette glands in the parapodial

Since the Discovery Investigations of the 1920s and 1930s, seawater temperatures have increased in the Atlantic sector by ∼1 °C; greater than the global mean rise. The aims of this paper were first to rescue the Discovery macrozooplankton data, second

The vast majority of pelagic bioluminescent organisms emit a blue light with emission maxima (λmax ) ranging from 450 to 490 nm. Among the known outliers, the tomopterids (Annelida: Polychaeta) are usually described as yellow-emitters (λmax = 565-570

Bioluminescence is the production of light from living organisms, a phenomenon which is commonplace in the ocean. For polychaetes, because many pelagic species are difficult to catch in good condition, they remain almost completely unstudied compared

1. 1. Direct response of 6 common Antarctic zooplankters (the euphausiid Euphausia superba, the copepods Calanoides acutus and Euchaeta antarctica, the amphipods Parathemisto gaudichaudii and Hyperiella antarctica, and the polychaete Tomopteris carpenteri)
