MAH Dept. of Invertebrate Zoology, Smithsonian Institution, Washington, D.C. 20007 Abstract Two new species of Goniasteridae, Astroceramus eldredgei n. sp. and Apollonaster kelleyi n. sp. are described from the Hawaiian Islands region. Prior to this occurrence, Apollonaster was known only from the North Atlantic. The Goniasteri- dae is the most diverse family of asteroids in the Hawaiian region. Additional in situ observations of several goniasterid species, including A. eldredgei n. sp. are reported. These observations extend documentation of deep-sea corallivory among goniasterid asteroids. New species occurrences presented herein suggested further biogeographic affinities be- tween tropical Pacific and Atlantic goniasterid faunas. Key words: Goniasteridae, Valvatida, deep-sea, Hawaiian Islands, predation Introduction Recent discoveries of new genera and species from deep-sea habitats along with new in situ video observations have provided us with new ecological insight into these poorly understood and formerly inaccessible settings (e.g., Mah et al. 2010, 2014; Mah & Foltz 2014). Hawaiian deep-sea Asteroidea are taxonomically diverse and occur in an active area of oceanographic and biological research (Chave and Malahoff 1998). New data on asteroids in this area presents an opportunity to review and highlight this diverse fauna. -

Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -
The Ciliate Orchitophrya Stellarum Viewed As a Facultative Parasite of Asteriid Sea Stars
Cah. Biol. Mar. (2007) 48 : 9-16 The ciliate Orchitophrya stellarum viewed as a facultative parasite of asteriid sea stars William B. STICKLE1, Eugene N. KOZLOFF2* and Margaret C. HENK1 (1) Department of Biological Sciences, Louisiana State University, Baton Rouge, Louisiana, 70803-1715, USA (2) Friday Harbor Laboratories, University of Washington, Friday Harbor, WA, 98250, USA *Corresponding author: Fax: (1) 206 543 1273. E-mail: [email protected] Abstract: Orchitophrya stellarum Cépède, 1907 is a ciliate that consumes sperm in the testes of male asteriid sea stars in the Pacific and North Atlantic oceans. Previous studies have reported its presence in smears and sections of testes, and we have also observed it in the spawn. This organism is easily cultured in seawater containing bacteria nourished by yeast extract or tissues from various marine invertebrates and the domestic chicken. During adaptation to culture conditions, the ciliates become smaller, the number of kineties is reduced, and the buccal cavity is shifted farther away from the anterior end. These changes are reversed if the ciliates are fed sperm of asteriid sea stars. Orchitophrya stellarum is therefore consi- dered to be a facultative parasite that can live indefinitely in situations where it can feed on bacteria and tissue detritus. It probably enters the testes of reproductively mature male sea stars by way of the gonopores. Resumé : Le cilié Orcitophyra stellarum vu comme un parasite possible des étoiles de mer astériide. Le cilié Orchitophrya stellarum Cépède, 1907, parfois trouvé dans les étoiles de mer asterides mâles dans les océans Pacifique et Atlantique Nord, se nourrit de spermatozoïdes. -
Fertilization Selection on Egg and Jelly-Coat Size in the Sand Dollar Dendraster Excentricus
Evolution, 55(12), 2001, pp. 2479±2483 FERTILIZATION SELECTION ON EGG AND JELLY-COAT SIZE IN THE SAND DOLLAR DENDRASTER EXCENTRICUS DON R. LEVITAN1,2 AND STACEY D. IRVINE2 1Department of Biological Science, Florida State University, Tallahassee, Florida 32306-1100 2Bam®eld Marine Station, Bam®eld, British Columbia VOR 1B0, Canada Abstract. Organisms with external fertilization are often sperm limited, and in echinoids, larger eggs have a higher probability of fertilization than smaller eggs. This difference is thought to be a result of the more frequent sperm- egg collisions experienced by larger targets. Here we report how two components of egg target size, the egg cell and jelly coat, contributed to fertilization success in a selection experiment. We used a cross-sectional analysis of correlated characters to estimate the selection gradients on egg and jelly-coat size in ®ve replicate male pairs of the sand dollar Dendraster excentricus. Results indicated that eggs with larger cells and jelly coats were preferentially fertilized under sperm limitation in the laboratory. The selection gradients were an average of 922% steeper for egg than for jelly- coat size. The standardized selection gradients for egg and jelly-coat size were similar. Our results suggest that fertilization selection can act on both egg-cell and jelly-coat size but that an increase in egg-cell volume is much more likely to increase fertilization success than an equal change in jelly-coat volume. The strengths of the selection gradients were inversely related to the correlation of egg traits across replicate egg clutches. This result suggests the importance of replication in studies of selection of correlated characters. -
Developmental Effects of Predator Cues on Dendraster Excentricus Larvae
Running head: Developmental Effects of Predator Cues on Dendraster excentricus Larvae Developmental Effects of Predator Cues on Dendraster excentricus Larvae: The Effects of Pugettia producta Effluent and Crustacean Dominant Plankton Effluent Claudia Mateo University of Washington Friday Harbor Laboratories Developmental Effects of Predator Cues on Dendraster excentricus Larvae Mateo 1 Abstract Previous findings supporting increased cloning in Dendraster excentricus (D. excentricus) larvae as a response to predator cues, in particular fish slime. Such findings report a “visual predator hypothesis”, suggesting that the larvae clone in order to become smaller and thereby avoid visual predators and possibly even non-visual predators. The experiment reported here builds upon earlier findings by studying the exposure of D. excentricus larvae to a kelp crab effluent (using Pugettia producta) and a crustacean dominant plankton effluent. Individual larvae were exposed to one of three treatments: the kelp crab effluent, plankton effluent, or filtered sea water, for approximately 66 hours. After this period, number of clones, number of larval arms, and the rudiment stage of each larvae was determined. Linear modeling showed significant results when comparing the kelp crab treatment to the control for cloning (p=0.024) and rudiment stage (p= 0.032); they also displayed significant differences for larval arm stage when comparing both the kelp crab effluent treatment (p= <0.001) and plankton effluent treatment (p= <0.001) to the control. These findings may support the visual predator theory, depending on whether D. excentricus larvae are able to differentiate predator cues, and, if so, to what specificity.

The recent sea star die-off throughout the eastern Pacific, known as Sea Star Wasting Disease, has prompted a need to understand spatial and temporal patterns of seastarassemblages and the environmental variables that structure these assemblages. We examined spatial and temporal patterns in sea star assemblages (composition and density) across regions in the northern Gulf of Alaska and assessed the role of seven static environmental variables (distance to freshwater inputs, tidewater glacial presence, exposure to wave action, fetch, beach slope, substrate composition, and tidal range) in influencing sea star assemblage structure before and after sea star declines.
