  author={Erik V. Thuesen and Steven H. D. Haddock},
A new species of deep-sea chaetognath, Archeterokrohnia docrickettsae n. sp. is described from a single specimen captured by the ROV Doc Ricketts ~2 m above the sea floor at 3245 m depth in the Pescadero Basin of the Gulf of California, Mexico. [] Key Result In life, the head and trunk sections were orange, while the tail section was translucent, a unique colour pattern not before seen in chaetognaths. Observations of its swimming behaviour in situ are given. Comparisons are made with the three other species…

The rare deep-living hyperiid amphipod Megalanceoloides remipes (Barnard, 1932): complementary description and symbiosis.

The colors of the hyperiid and of some parts of the Apolemid were very similar, thus supporting the notion that some hyperiids tend to mimic the color of its host, and the first data on its symbiotic association from in situ observations are presented.



A golden age of gelata: past and future research on planktonic ctenophores and cnidarians

The study of the natural history of gelatinous zooplankton (‘gelata’) reached a high point at the end of the 19th century, when scientists first began to understand the phylogenetic and ecological

Heterokrohnia longicaudata, a new species of chaetognatha from Antarctic waters

A new bathypelagic species of the genus Heterokrohnia, H. longicaudata, is described and separated from the others, found at great depths near Elephant Island, in the atlantic sector north of the Antarctic Peninsula.

The characters which have been advanced to separateArcheterokrohnia Casanova, 1986, fromHeterokrohnia Ritter-Záhony, 1911, are discussed; they are considered to be insufficient to warrant the

Bioluminescent Organs of Two Deep-Sea Arrow Worms, Eukrohnia fowleri and Caecosagitta macrocephala, With Further Observations on Bioluminescence in Chaetognaths

The discovery of bioluminescence in a second chaetognath phylogenetically distant from the first highlights the importance of bioterrorism among deep-sea organisms.

Pigments of meso- and bathypelagic chaetognaths

It is inferred that carotenoids in chaetognaths are not formed by the deposition of food pigments in the intestinal tissue, but are synthesized by the chaetoglaths themselves.

Enzymatic activities and metabolic rates of pelagic chaetognaths: Lack of depth‐related declines

No decline in metabolic rate nor in enzyme activities can be ascribed to depth of occurrence for pelagic chaetognaths, in contrast to the rapid declines in metabolic potential with depth that have been observed for Pelagic fish and crustaceans.
