“…In contrast Parathemisto gaudichaudii (Guerin) and Hyperia spp. (Hyperiidae) are loosely associated with salps or medusae during the juvenile stages only (Harbison et al 1977, Laval 1980, Dittrich 1988. Associations also seem to be sex-dependent.…”

“…Recently maternal care has been discovered in a species of the family Oxycephalidae, Oxycephalus clausi Bovallius, parasitic on the ctenophore Ocyropsis crystallina (Rang) in the Gulf of California (Gasca & Haddock 2004), in addition to the well-known hyperiid family Phronimidae (Harbison et al 1977, Laval 1980. Many new combinations of associations between hyperiids and medusae were also revealed in the surface and deepwaters off California with an ROV and SCUBA (Gasca et al 2006).…”

“…(Pronoidae) are encysted in the mesogloea of nectophores and bracts of physonect siphonophores (Fig. 5B), and are suggested to feed on predigested food from the radial canals of the host (Harbison et al 1977). Adult females tend to continue to stay with the host for continuous oviposition and/or maternal care, while males are free-swimming predators (Harbison et al 1977, Laval 1980.…”

Abstract:Since marine medusae and ctenophores harbor a wide variety of symbionts, from protists to fish, they constitute a unique community in pelagic ecosystems. Their symbiotic relationships broadly range from simple, facultative phoresy through parasitisim to complex mutualism, although it is sometimes difficult to define these associations strictly. Phoresy and/or commensalism are found in symbionts such as pycnogonids, decapod larvae and fish juveniles. Parasitism and/or parasitoidism are common in the following symbionts: dinoflagellates, ciliates, anthozoan larvae, pedunculate barnacles, anuropid isopods, and hyperiid amphipods. Mutualism is established between ctenophores and gymnamoebae, and between rhizostome medusae and endosymbiotic dinoflagellates. More information on symbiotic apostome ciliates, anthozoan larvae and hyperiid amphipods is definitely needed for further studies in consideration of their high prevalence and serious damage they can inflict on their hosts. The present paper briefly reviews previously published data on symbionts on these gelatinous predators and introduces new information in the form of our unpublished data.

Size‐based changes in trophic ecology and nutritional quality of moon jellyfish (Aurelia labiata)

et al. 2023

Despite their seemingly watery constitution, jellyfish are eaten by a diverse range of predators. However, while the role of jellyfish in marine food webs is gaining attention, the nutritional value of these gelatinous organisms and how it varies remain poorly understood. In this study, we aimed to connect jellyfish food web biology and nutrition by determining the relationship between jellyfish size, diet, and nutritional quality. We measured stable isotope (SI) and fatty acid (FA) profiles of particulate organic matter (POM), plankton size classes, and gelatinous zooplankton collected from a coastal site in British Columbia, Canada, in July and September 2019. Gelatinous zooplankton comprised 152 Aurelia labiata collected across both months (bell diameters = 19–225 mm), and 2 Aequorea victoria and approximately 30 Pleurobrachia bachei collected in July for comparison. According to FA trophic markers and chlorophyll a concentrations, the POM was a mix of phytoplankton, microzooplankton, bacteria, and detritus. According to δ15N, POM was ~1 trophic level lower than plankton. All gelatinous zooplankton had low FA content (5–6 μg/mg dry mass) compared with zooplankton (43–65 μg/mg dry mass). A Bayesian mixing model (MixSIAR) was used to assess the contributions of POM and plankton to A. labiata diet, which demonstrated a size‐based shift from 40% plankton at 19 mm to 70%–75% at 225 mm. Similarly, both δ13C and δ15N increased with size and A. labiata of 19 mm were ~1 trophic level lower than A. labiata of 225 mm. We also documented size‐based changes in nutritional quality of A. labiata, where C:N decreased with A. labiata size, and essential FAs arachidonic acid (ARA) and docosahexaenoic acid (DHA) increased with size while eicosapentaenoic acid (EPA) did not change. A. labiata were elevated in ARA compared with other zooplankton, ranging from 1% to 9%. The changes in C:N and DHA of A. labiata with size mirrored the changes in their diet, but changes in ARA and EPA did not. Overall, these findings emphasize the importance of considering jellyfish size and taxonomy when evaluating nutritional pathways through jellyfish in marine food webs, and support that diet is one important driver of jellyfish biochemical composition.
