Nudibranch Food List of the Worldwide Food Habits of Nudibranchs by Gary McDonald The "list of the worldwide food habits of nudibranchs" was originally available on the web as a supplement to two articles published in the Veliger: McDonald & Nybakken, 1997 & 1999. On 5 November 2014, it was brought to my attention that the list is no longer available on the web, so I have uploaded it to eScholarship in order to make it available once again.

Nudibranch Food A List of the Worldwide Food Habits of Nudibranchs by Gary R. McDonald Long Marine Laboratory, 100 Shaffer Rd., Santa Cruz, Cal. 95060 [email protected] and James W. Nybakken Moss Landing Marine Laboratories, P.O. Box 450, Moss Landing, Cal. 95039 [email protected] This list is an attempt to compile all of the published food data for nudibranchs. More than 4,600 nudibranch papers were perused in an effort to find as much of the published food data as possible. More than 1,000 papers mentioned nudibranch food. Included are all of the articles that we were able to obtain prior to June 1996. The list is arranged phylogenetically so that trends in food preferences within various groups of nudibranchs may be seen more easily. The food items are listed alphabetically below each species of nudibranch. The author, date, and page number which mention prey species for each nudibranch are listed below each food item. If a subsequent author cited another paper as the source of the food data, the original author is cited in brackets. A P included in the brackets indicates that the subsequent author (as well as the original author) observed the food preference; (e.g. under Hopkinsia rosacea, McDonald & Nybakken, 1978:111 cite McBeth, 1971 as stating that H. rosacea eats Eurystomella bilabiata. McDonald & Nybakken also observed H. rosacea eating E. bilabiata). If a nudibranch species or a prey species was cited under an older name in the original paper, the older name is listed in brackets. For many prey species, we were unaware which names are junior synonyms, so the same prey species may be listed more than once under the same nudibranch species (e.g. Obelia longissima and Laomedea longissima). We wish to thank Terry Gosliner for help with many of the junior synonyms of the nudibranchs. There is still confusion about some of the nudibranch species which we list (e.g. A. tuberculata Cuvier is a currently accepted valid species, while A. tuberculata Müller is considered to be a junior synonym of A. pseudoargus (Rapp, 1827)). A question mark accompanying a prey species name indicates a questionable prey species identification. A question mark accompanying an author and date citation indicates that the author was unsure whether the nudibranch eats that prey species. If we list a nudibranch species as being "on" a prey species, the nudibranch was not reported to eat the prey species, but was only found on, or in association with, the species. We have endeavored to check the original citations listed by subsequent authors with the following exceptions: 1) We were unable to obtain by interlibrary loan a copy of Ehrenberg, 1831; (vide post Phyllodesmium hyalinum on Xenia sp. cited by Rudman, 1981b:231 citing Ehrenberg). 2) We did not check all field guides to local marine faunas or other popular books (e.g. Riedl, 1963; or Vevers, 1955, The animal world of the sea, Rathbone, London, cited by Thompson, 1964:292 for Dendronotus frondosus eating Tubularia sp.). We do not list an original author under a particular prey species, if the "original" author was incorrectly cited by a subsequent author, e.g.: file:///C|/Users/Gary/Desktop/nudibranch_food.html[12/23/2011 9:53:18 AM] Nudibranch Food 1) The subsequent author lists a prey species as a food item while the original author stated that the nudibranch was found on the "prey" species, but did not state specifically that the nudibranch eats the "prey" species (e.g. vide post Okenia mediterranea where Valdes & Ortea, 1995:225 cite Alcyonidium mytili as a prey species and list Cervera, Lopez-Gonzalez, & Garcia-Gomez, 1991 as the source of this information, but Cervera, Lopez- Gonzalez, & Garcia-Gomez, 1991:64 state that O. mediterranea was found on Alcyonidium cf. mytili, but do not state specifically that the nudibranch eats the bryozoan). 2) The original author does not mention the prey species that the subsequent author cites (e.g. vide post Cuthona divae where Christensen, 1977:131 states that Marcus, 1961 lists Hydractinia as a substrate for C. divae but Marcus, 1961 does not mention Hydractinia or any other substrate for C. divae. Likewise for Cuthona concinna, Brown, 1980:249 says "possibly Dynamena pumilla is taken around Canada and the U.S.A. (Meyer, 1971)." But Meyer, 1971:146 states: "No food preference was determined..."). Numerous similar examples occur throughout the list.

Diversity of Norwegian sea slugs (Nudibranchia): new species to Norwegian coastal waters and new data on distribution of rare species. Fauna norvegica 32: 45-52. A total of 5 nudibranch species are reported from the Norwegian coast for the first time (Doridoxa ingolfiana, Goniodoris castanea, Onchidoris sparsa, Eubranchus rupium and Proctonotus mucro- niferus). In addition 10 species that can be considered rare in Norwegian waters are presented with new information (Lophodoris danielsseni, Onchidoris depressa, Palio nothus, Tritonia griegi, Tritonia lineata, Hero formosa, Janolus cristatus, Cumanotus beaumonti, Berghia norvegica and Calma glau- coides), in some cases with considerable changes to their distribution. These new results present an update to our previous extensive investigation of the nudibranch fauna of the Norwegian coast from 2005, which now totals 87 species. An increase in several new species to the Norwegian fauna and new records of rare species, some with considerable updates, in relatively few years results mainly from sampling effort and contributions by specialists on samples from poorly sampled areas. doi: 10.5324/fn.v31i0.1576.

This study was carried out, through a total of 271 scuba dives, from 2017 to the beginning of 2020 in four sites located along the Ionian coasts of Sicily: Catania, Aci Trezza, Santa Maria La Scala and Santa Tecla. Through a photographic data collection, 95 taxa, representing 17.27% of all Mediterranean marine Heterobranchia, were reported. The order with the highest number of found species was that of Nudibranchia. Among the study areas, Catania, Santa Maria La Scala and Santa Tecla had not a remarkable difference in the number of species, while Aci Trezza had the lowest number of species. Moreover, among the 95 taxa, four species considered rare and six non-indigenous species have been recorded. Since the presence of a high diversity of sea slugs in a relatively small area, the central-eastern coast of Sicily could be considered a zone of high biodiversity for the marine Heterobranchia fauna. KEY WORDS diversity; marine Heterobranchia; Mediterranean Sea; sea slugs; species list.

  • Subtidal Ecology of Frenchman Bay Establishing Long-Term Monitoring Sites J
    Subtidal Ecology of Frenchman Bay Establishing long-term monitoring sites J. Alex Brett College of the Atlantic Spring, 2011 Abstract Long-term monitoring programs are an essential component of understanding population dynamics, particularly in response to anthropogenic activity. The marine environment of Downeast Maine is subject to a wide range of factors resulting from human actions, including commercial fishing, climate change, and species introductions. In order to provide baseline data to understand the impacts of these actions I used photoquadrats to survey the rocky subtidal zone at two sites in Frenchman Bay, Maine. The data demonstrated interesting trends in population distribution patterns in the Bay; I found high levels of variation both between sites and between individual quadrats within sites. The site at Bar Island had a significantly higher density of filamentous red algae than Long Porcupine. As predicted by past studies, percent cover estimates of filter feeders were found to vary significantly between horizontal and vertical surfaces. The data from this study support earlier conclusions about marine invertebrate population patterns, and indicate the importance of fixed plots for long-term surveys to reduce the effect of environmental variation on survey results. Introduction At present there appears to be little current understanding of the population dynamics of the benthic marine life of Downeast Maine, which is a knowledge gap that needs to be addressed. The bulk of population studies on marine life have focused on commercially important species, such as scallops (Hart 2006) and bony fishes (Brodziak and Traver 2006, Mayo and O’Brien 2006), or ecologically sensitive species such as eelgrass (Disney and Kidder 2010).
