113-125 on Three Rare Doridiform Nudibranch
J. mar. biod . Ass. India, 1974, 16 (1): 113-125 ON THREE RARE DORIDIFORM NUDIBRANCH MOLLUSCS FROM KAVARATTI LAGOON, LACCADIVE ISLANDS K. ViRABHADRA RAO, P. SiVADAS* AND L. KRISHNA KUMARY National Institute of Oceanography, Panaji, Goa. ABSTRACT. The paper deals with Asteronotus caespitosus (van Hasselt) under the family Dori- didae and Phyllidia (Phyllidia) varicosa Lamarck and Phyllidia (Phyllidiella) zeylanica Kelaart under the family Phyllidiidae. All the three are new records for the Laccadive group of Islands. The first two have not beeii recorded even from the coasts of the main land of India. The descriptions of external morphology and colouration of all the three forms are based on fresh living material examined in the field. Their geographical distribu tion and some aspects of the internal anatomy arealso dealt with. In the Indo-Pacific region, there seems to be only one species under the genus Asteronotus Ehrenberg, namely A. caespitosus. A. mabillaBeigh, A. bertranaBergh, A. exanthemata (Kelaart), A. crescentica (CoUingwood), A. hemprichi (Ehrenberg), and A.fuscus O'Donoghue are also shown to be synonymous with A. caespitosus. P. (P) zeylanica is an extremely rare and little known species which has been recorded only for the third time in the past 113 years after its first description by Kelaart in 1859. INTRODUCTION THE Laccadive group of Islands forms a distinct geographical entity with characte* ristic faimal assemblages of their own, the study of which because of their intrinsic interest has received much attention of the Indian National Science Academy under a Scientific project' Investigations of the Arabian Sea Islands'. A large number Of molluscan species inhabiting Kavaratti and nearby Islands have been collected under the project. -
Point Lobos Nudibranch Project Topics for Tonight
Point Lobos Nudibranch Project Topics for Tonight • Project Design, Location and Transect Selection • Nudibranch Identification • Species in the Study • Look-alikes • Sampling Techniques and Data Sheets • Q & A Project Design • Project Design, Location and Transect Selection • Science goals are still being defined. • Hope is to maximize the value of any data we collect. • Cover a variety of species and habitats. • Ease of study was also important. • Sites need to be near each other to maximize data collection time. • Sites need to be easy to find. • Transects need to be easy identify for repeatability. • Species covered need to be common and diverse. Locations • We have chosen two areas for study. • The North end of the Middle Reef • The North end of the Hole-in-the-wall Reef • Each reef will be divided into 4 transect zones. • East Wall • North Wall • West Wall • Top (defined as anything with less than 45 degrees of slope. • Actual transect areas are TBD and will need to be surveyed. • Each transect area needs to be roughly the same size • Transects must be easily identifiable. Locations Rationale • Middle Reef and Hole-in-the-wall Reefs are easily locatable underwater. • Both sites have good populations of nudibranchs. • Both sites have diverse habitat areas. • Hole-in-the-wall Reef may be lacking in “top” and North areas. • A survey will help here. • We’re open to other suggestions. Species in the Study • We have 14 species in the study. • All are at least reasonably common in Whaler’s Cove. • They represent a wide variety of species and prey items. -
Baeria Rocks Ecological Reserve - Subtidal Survey 2018
BC Parks Living Lab for Climate Change and Conservation Final Report (Contract #TP19JHQ008) Baeria Rocks Ecological Reserve - Subtidal Survey 2018 Isabelle M. Côté and Siobhan Gray Department of Biological Sciences, Simon Fraser University/ Bamfield Marine Sciences Centre [email protected], [email protected] 8 February 2019 Dive surveys of fish and invertebrates were carried out at Baeria Rocks Ecological Reserve on 7 June 2018, to continue a monitoring effort that began in 2007. Twelve divers (7 students from the Scientific Diving class of the Bamfield Marine Sciences Centre (BMSC), two Sci Diving Instructors, two course teaching assistants, and one additional diver) were present. All divers were well trained in survey techniques and identification. On each dive, one diver was assigned to tending duties, leaving 11 divers in the water. Surveys were conducted between 10.00 and 13.30 by five dive teams. Two teams conducted timed roving surveys and three teams conducted transects. As in previous years, the teams were deployed around the north islets for the first dive, and around the south islet for the second dive, alternating roving and transect teams along the shore (Figure 1). Roving survey method Each roving team carried out a 40-50 min roving survey, from a maximum depth of 50 ft (14.5 m) depth (where possible), to the top of the reef, swimming in a semi- systematic zigzag pattern from deep to shallow water. Both divers counted every individual observed of each species listed on an underwater roving survey sheet. When a species was very abundant (i.e. more than ~100 individuals), surveyors recorded numbers as ‘lots’. -

Frank The opisthobranch molluscs of Oregon have been little studied, and little is known about the biology of many species. The present study consisted of field and laboratory observations of Cape Arago opistho- branchs. Forty-six species were found, extending the range of six north- ward and two southward. New food records are presented for nine species; an additional 20 species were observed feeding on previously recorded prey. Development data are given for 21 species. Twenty produce plank- totrophic larvae, and Doto amyra produces lecithotrophic larvae, the first such example known from Eastern Pacific opisthobranchs. Hallaxa chani appears to be the first eudoridacean nudibranch known to have a subannual life cycle. Development, life cycles, food and competition, iv ranges, and the ecological role of nudibranchs are discussed. Nudi- branchs appear to significantly affect the diversity of the Cape Arago encrusting community. -

Continuing Education Debuts with Doug Mason As Featured Speaker
BETWEEN the TIDES Friends of Fitzgerald Marine Reserve J u n e 2 0 1 2 Continuing Education Debuts with Doug Mason as Featured Speaker The first FFMR Continuing Education event, co- ordinated by Linda Ciotti and hosted by Mary DeLong and Jamie Rioto, was held Sunday, April 15, in Princeton. The featured speaker was Doug Mason, noted nudibranch expert. Mason, a science teacher at California High School in San Ramon, spoke of the decline of nudibranchs in the Central California coastal region. Mason began by explaining that most common nu- dibranch larvae in our area are planktonic, and feeding on other plankton enables them to drift in the water table for weeks or months, up to hundreds of kilometers from their place of origin. Only a few species (Doto amyra and Phidiana hiltoni), are lecithotrophic—their larvae feed on the egg yolk and thus are limited in their travel.

I have indexed them only for information concerning systematics, taxonomy, nomenclature, & description of taxa (as these are my areas of interest, and to have tried to index for areas such as physiology, behavior, ecology, neurophysiology, anatomy, etc. would have made the job too large and I would have given up long ago). This is a working list and as such may contain errors, but it should allow you to quickly find information concerning the description, taxonomy, or systematics of almost any species of nudibranch. The phylogenetic hierarchy used is based on Traite de Zoologie, with a few additions and changes (since this is intended to be an index, and not a definitive classification, I have not attempted to update the hierarchy to reflect recent changes). The full citation for any of the authors and dates listed may be found in the nudibranch bibliography at http://repositories.cdlib.org/ims/Bibliographia_Nudibranchia_second_edition/. Names in square brackets and preceded by an equal sign are synonyms which were listed as such in at least one of the cited papers. If only a generic name is listed in square brackets after a species name, it indicates that the generic allocation of the species has changed, but the specific epithet is the same. -
