WHILE occupied with field-work on Siphonophora, I placed six small Pleurobrachia sp. measuring about 2.5 mm. in length in a watch-glass at 1100 hr. on April 29. An hour later I noticed that eggs were being extruded through the ectoderm over the gastrovascular canals. Since the fertilization membrane was present as the eggs were being extruded, it would

Despite their importance, this diverse group of marine predators has remained relatively poorly known, with both the species and higher-level taxonomy of the phylum in ...Leonid L, Moroz +2 more
