Abstract:
A new genus, Mesoikopleura, in the family Oikopleuridae (Lohmann, 1915), is described from several specimens collected at low mesopelagic depth (710–860 m) during different cruises using the ‘Johnson-Sea-Link’ submersibles, and from one collected by the ‘Cyana’ submersible during the ‘Gyrocean’ cruise. Three species of this new genus are described: M. enterospira, M. youngbluthi and M. gyroceanis. One of the species already described as belonging to the genus Pelagopleura is moved to the genus Mesoikopleura. Consideration of the genera closely related to Mesoikopleura leads to the division of the subfamily Oikopleurinae into two groups at the level of super genera: Labiata and Alabiata.

Abstract:
Abstract Appendicularians are free-swimming pelagic tunicates with a trunk and chordate tail, found in all oceans, though most species are warmwater forms. Whilst the majority are found in the euphotic zone, an increasing number of mesopelagic and even bathypelagic species have been described recently. Most are only a few millimetres long, (including the tail), but some may be much larger, up to 8-9 cm. All appendicularians in the three families (Oikopleuridae, Fritillariidae, and Kowalevskiidae) secrete and inhabit a most complicated mucilaginous filtering house with many chambers and two levels of filters (Chapter 6). In the subfamily Bathochordaeinae, where tail length may be up to 70 mm, the house is remarkably large, more than 1 min diameter (Barham, 1979; Hamner and Robison, 1992). Although in the Fritillariidae, the house was long described as a small filtration system that the animal does not inhabit, Flood (1994) has recently shown that fritillariid houses are homologous to those of the oikopleurids (Chapter 7). Fol’s description and drawing of the house of Kowalevskiidae have recently been shown to be inaccurate, by observations from manned submersibles (Chapter 6). The house is secreted by regions of special secretory epithelia on the trunk, the oikoplasts (section 2.3.1.7 and Chapter 6). The Appendicularia are thus very different in organization to the Thaliacea, and do not show alternation of generations, nor, as adults, (unlike any other tunicate) do they have an external cellulosic tunic. Instead, a glycocalyx consisting of chondronic mucopolysaccharides (Korner, 1952) covers the outer epithelium (if this is present, see p. 33). The first good descriptions of general anatomy are from Fol (1872); detailed anatomy and histology can be found in Salensky (1903, 1904a-c), Ihle (1906), Martini (1909a,b), Vernieres (1933), Lohmann (1933) and Bogoraze and Tuzet (1969a, 1974).

Abstract:
Abstract The Classification of Appendicularia (Tunicata). History and Current State (Fenaux, 1993) may be consulted for a more extended and detailed account of the classification, and its historical development, than is possible in this chapter. The keys for determination given here follow the principles explained by Lohmann and Biickmann (1926) and revised by Lohmann in 1933-1934, with additions and modifications. For the Oikopleuridae they are primarily based on the structure of the digestive tract, but for the Fritillariidae on very diverse criteria. For these reasons, and particularly for the Fritillariidae, numerous characters must be used to determine the species. Because they are particularly fragile, appendicularians are frequently determined with difficulty. Problems with collection and preservation techniques are responsible for much of this difficulty (Fenaux, 1976a), but even with living or perfectly preserved specimens, there may be some doubt of the exact determination, for several main reasons.

Abstract:
Abstract The ‘house’ building capacity was early considered an important feature of the appendicularians, and the name ‘Oikopleura’ was coined by Mertens (1830, p. 210) soon after their original description by Chamisso and Eysenhardt (1821). OiKoc; (Oikos) is Greek for ‘house’ and 1rX.eupa (pleura) is Greek for ‘rib’ or the side of an animal, but came early to be applied to the lining membrane of the chest wall (Skinner, 1961). Thus, Mertens’ term ‘Oikopleura’ most likely points to the respiratory function which he erroneously assigned to the houses of these animals. However, it took almost 30 years before Mertens’ (1830) observation of a house surrounding an appendicularian was verified by Allman (1859). He suggested the house to be a ‘definitely shaped secretion, destined to act as a nidamental covering for the ova’. Moss (1870) gave some structural notes on inflating houses and presented interesting chemical data on the house material of an unidentified oikopleurid species, but did not comment on its function. Fol (1872) gave the first detailed description of the external houses in all three main families of appendicularians. His drawings still represent the most detailed published accounts of those of the Fritillariidae (26 species) and Kowalewskiidae (two species). A single photograph of a Kowalewskia house (Alldredge, 1976c) and a behavioural study of Fritillaria pellucida (Bone et al., 1979) add little to this knowledge. For the Oikopleuridae (about 29 species) on the other hand, Fol’s (1872) description of the house of Oikopleura albicans (at that time named O.cophocerca) was soon supplemented by the study by Eisen (1874), probably on O.dioica. Whereas Fol (1872, p. 495) suggested that the house served some protective function against preda-tors, Eisen (1874, p. 6) was the first to vaguely suggest it served ‘till at infora naringsamnen till munoppningen’ (to introduce nutritional substances to the mouth opening). However, undoubtedly the detailed structural studies of Lohmann (1898, 1899c, 1909a, 1933, 1934), mostly on O.albicans, were needed before any precise ideas could be established on the functional significance of the house with respect to feeding ecology. The great complexity and extreme fragility of appendicularian houses has been a challenge for numerous subsequent investigators and improved understanding of the precise structure and mode of operation of the house has only slowly emerged.

Abstract:
Abstract Lohmann (1898, 1899, 1909a, 1933) was the first investigator to recognize the true function of the appendicularian house, which is to concentrate and collect particulate matter from the sea for feeding. He examined the gut contents of Oikopleura albicans and in this way identified an entirely new size class of plankton in the sea, which he called ‘nanoplankton’ (Lohmann, 1909a). The structure of the house is described in detail in Chapter 6; it is remarkably complex and its operation is only well understood in detail in a few oikopleurid species, and less well in a single fritillariid. Essentially, there are in oikopleurids usually three filters involved in food collection; their structure determining the size class of particles a given species can feed upon. The inhalent flow produced by oscillation of the tail draws water into the house via an external relatively coarse filter, then a food collecting filter or trap concentrates particulate material, which is drawn along a short tube to the mouth by the action of spiracular cilia. After entering the pharynx, the particles are trapped on a mucous filter and they enter the oesophagus.

Abstract:
Abstract Although a good deal is known of the broad outlines of appendicularian distribution in different oceans, only at a few favoured sites has sampling been sufficiently detailed, and carried on for long enough, to gain a reasonably ‘complete’ idea of their horizontal and vertical distribution over time. Sampling presents some difficulties, and much of the information from particular areas on the presence or absence of species and their abundance must be regarded as provisional only. Most of our knowledge of global appendicularian distribution has come from oceanographic expeditions during the 19th and 20th centuries, which means that each site (station) was usually sampled only once. The few studies that have achieved repeated sampling from the same station over time have shown marked seasonal qualitative variations in the catch, hence the absence of a particular species in a single sample should not be taken as absolute proof that that species is absent from the area. However this is not the only sampling difficulty. Due to size differences between species, and increase in size with age within species, the mesh size of the plankton nets used will influence the nature of the samples obtained, both qualitatively and quantitatively. A very clear example of the magnitude of this sampling bias was provided by Fenaux (1986b), who took simultaneous vertical samples in the Mediterranean with two nets of mesh size 200 and 53 μ,m. Many fewer specimens were caught by the net with the larger mesh, indeed, to agree with the catch of the 53 μ,m net, that of the 200 μ,m net had to be multiplied by a factor of 2.9 for Oikopleuridae and 4.6 for the smaller Fritillariidae. Another difficulty in sampling has been raised by recent interesting submersible and diver observations, which indicate that appendicularians may be extremely abundant in very thin layers only a few metres thick, and these layers may be patchy (Deibel et al., unpublished). All of these sampling problems, in particular the temporal and spatial inhomogeneity of appendicularian populations, means that most of the data we have on appendicularian distribution is incomplete.

Abstract The first serious attempt to study appendicularian development was that of Delsman (1911, 1912), which still remains the only description of cleavage and embryonic development. The chronology of development in cultured Oikopleura dioica was given by Galt (1972), Paffenhofer (1973) and Fenaux (1976). Fenaux and Gorsky (1983) decribed the development and growth of O.longi.cauda, the only hermaphroditic oikopleurid to be cultured so far; they found a similar general pattern with a few differences in detail. Most of the information given here concerns O.dioica. A comprehensive review of the reproductive biology of appendicularians can be found in Galt and Fenaux (1990b).

Abstract:
Abstract Bioluminescence is a conspicuous feature of many marine organisms, and among the pelagic Tunicata it is well documented in the Pyrosomida (section 1.2.2) and in certain oikopleurid Appendicularia, whose mucoid feeding houses emit light. Giglioli (1870), who reported multicoloured luminescence from the tail of unidentified species of appendicularians, probably actually observed iridescence from the caudal muscle bands, as there is no evidence of caudal luminescence or multiple wavelength emissions from a single animal. We owe to Hans Lohmann (1899a, 1933) the first reliable accounts of light production by appendicularian tunicates. He described brilliant greenish flashes emanating from the trunks of free-swimming Oikopleura albicans as they made contact with surfaces or were otherwise agitated. He further reported that during expansion of the house a brilliant light emanated continuously from the animal’s trunk, (he speculated that such luminescence would serve to deter predators during this vulnerable operation). The expanded house (as Lohmann observed) also produces light from unknown but consistently organized sources in response to agitation or prodding. Finally, Lohmann noted that even discarded houses emitted flashes upon stimulation. Lohmann suggested that light was produced by ‘fluorescent’ secretions from the oral glands and from parts of the oikoplast epithelium. Since other species, including members of the Fritillariidae, produced similar secretions, Lohmann (1933) supposed that all appendicularians were luminescent. Harvey (1952) concluded from Lohmann’s
