Individuals of the rabbitfish Siganus rivulatus (Siganidae) and surgeonfish Zebrasoma desjardinii (Acanthuridae) were observed feeding on ctenophores and scyphozoans in the northern Red Sea during late spring and early summer seasons between 2010 and 2015. Siganus rivulatus and Z. desjardinii, considered nominally herbivorous, preyed on relatively large ctenophores until disintegration, and on the moon jellyfish Aurelia aurita (Scyphozoa) until they sank to the bottom. Siganus rivulatus was the… 

Benthic ctenophores (Platyctenida: Coeloplanidae) in South Florida: predator–prey interactions

Field and laboratory observations and laboratory experiments revealed diverse invertebrate and fish taxa that prey on both ctenophore species, and add to the limited knowledge base of predator–prey dynamics in both C. waltoni and V. multiformis.

Versuriga anadyomene, a newly recorded scyphozoan jellyfish (Scyphozoa: Rhizostomae) in Chinese waters

The rhizostome jellyfish found in Beibu Gulf, South China Sea, on 27 May 2015 was the first record of the genus Versuriga and the species V. anadyomene in Chinese seas and may be attributed to physical transport from the coastal waters of South East Asia.

Overwintering tropical herbivores accelerate detritus production on temperate reefs

Rabbitfish surpassed temperate herbivores, leading to a fivefold acceleration in the transformation of macrophyte standing stock to detritus, a function usually attributed to sea urchins in kelp forests, which suggests that further warming and tropicalization will not only increase primary consumption and affect the habitat structure of temperate reefs but also increase detritUS production.

Microbiome patterns across the gastrointestinal tract of the rabbitfish Siganus fuscescens

This is the first assessment of the bacterial diversity associated with the gut of S. fuscescens and highlights the need to consider the variability across different gut locations and sites when analyzing fish gut microbiomes.

Cnidarian Jellyfish: Ecological Aspects, Nematocyst Isolation, and Treatment Methods of Sting.

This chapter aims to present the data about the morphological, ecological, toxicological, epidemiological, and therapeutic aspects regarding cnidarians with the purpose to summarize the existing knowledge and to stimulate future perspectives in the research on these organisms.

This book reviews the most recent knowledge on cellular, molecular, physiological, and developmental aspects of various marine species to give the readers a new and invaluable perspective on the scientific, bioinformatics, bioengineering, medicinal, aquacultural, and environmental value and exquisiteness of marine organisms.

Effect of different derivatization protocols on the calculation of trophic position using amino acids compound-specific stable isotopes

This paper evaluates the use of the EZfaast amino acid derivatization kit (chloroformate) and compares it to the isotopic results of two other derivatized methods and highlights new considerations for working with AA-CSIA that might account for some of the variations in the results and lead researchers to modify constants in the equation.



Food and feeding habits of the Lessepsian migrants Siganus luridus Ruppell, 1828 and Siganus rivulatus Forsskal, 1775 (Teleostei: Siganidae) in the southern Mediterranean (Libyan coast)

Both species seem to be well established in the southcentral Mediterranean, with Siganus luridus showed a stronger affinity for brown algae while S. rivulatus targets a broader range of food items, with Rhodophyta and Chlorophyta algae playing a pronounced role in its diet.

Diet of the Lessepsian fishes, Siganus rivulatus and S. luridus (Siganidae) in the eastern Mediterranean : A bibliographic analysis

The Lessepsian fishes Siganus rivulatus and S. luridus are common herbivores in the eastern Mediterra- nean, where they adapted themselves to the algal resources of the new environment, and have considerably modified their diet to adapt themselves to newAlgal resources, which differ significantly from those found in the Red Sea.

Interactions of pelagic cnidarians and ctenophores with fish: a review

Medusae, siphonophores and ctenophores (here grouped as `pelagic coelenterates') interact with fish in several ways. Some interactions are detrimental to fish populations, such as predation by

Natural Food of the Herbivorous Rabbitfish (Siganus spp.) in Northern Red Sea

The contents of stomach and intestines of specimens of Siganus rivulatus, S. luridus and S. argenteus from the Gulf of Elat were analysed. The percentage of each algal and seagrass species in the

Jellyfish as Prey: Frequency of Predation and Selective Foraging of Boops boops (Vertebrata, Actinopterygii) on the Mauve Stinger Pelagia noctiluca (Cnidaria, Scyphozoa)

Estimation of predation frequency by the commercially valuable Mediterranean bogue, Boops boops, on the mauve stinger jellyfish, Pelagia noctiluca, in the Strait of Messina shows that female jellyfish gonads had significantly higher energy content than male gonads due to more lipids and that gonad had six-fold higherEnergy content than the somatic tissues due to higher lipid and protein concentrations.

Opportunistic feeding by the fungiid coral Fungia scruposa on the moon jellyfish Aurelia aurita

The authors' observations revealed that the large-mouthed solitary fungiids can consume relatively large prey organisms, which are not available to other corals, as an additional source of protein.

Hidden ecosystem function of rabbitfishes? Siganus fuscescens feeds on the soft coral, Sarcophyton sp.

The authors' observations indicate that chemical toxins and sclerites did not deter S. fuscescens from feeding on Sarcophyton and provide evidence that the feeding habits of some coral reef-associated fishes might be oversimplified and should be validated on a speciesby-species basis.

Diet Adaptations of Lessepsian Migrant Rabbitfishes, Siganus luridus and S. rivulatus, to the Algal Resources of the Mediterranean Coast of Israel

The algal partitioning in the Red Sea disappeared in the southern area of the Mediterranean as an adaption to the environment and developed in the northern area probably due to the prevalent rocky areas with their algal habitats.


The diet of two Erythrean algivorous siganid fish was studied off the Shiqmona vermetid reef, south of Haifa Bay, Israel, in conjunction with the spatial and seasonal variability in composition of the local algal community, suggesting that in reef-dwelling siganids, weakening of dietary niche-parti...
