Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism
Molecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism Ryutaro Goto1,2*, Tomoko Okamoto2, Hiroshi Ishikawa3, Yoichi Hamamura4, Makoto Kato2 1 Department of Marine Ecosystem Dynamics, Atmosphere and Ocean Research Institute, The University of Tokyo, Kashiwa, Chiba, Japan, 2 Graduate School of Human and Environmental Studies, Kyoto University, Kyoto, Japan, 3 Uwajima, Ehime, Japan, 4 Kure, Hiroshima, Japan Abstract The Echiura, or spoon worms, are a group of marine worms, most of which live in burrows in soft sediments. This annelid- like animal group was once considered as a separate phylum because of the absence of segmentation, although recent molecular analyses have placed it within the annelids. In this study, we elucidate the interfamily relationships of echiuran worms and their evolutionary pattern of feeding mode and sexual dimorphism, by performing molecular phylogenetic analyses using four genes (18S, 28S, H3, and COI) of representatives of all extant echiuran families. Our results suggest that Echiura is monophyletic and comprises two unexpected groups: [Echiuridae+Urechidae+Thalassematidae] and [Bone- lliidae+Ikedidae]. This grouping agrees with the presence/absence of marked sexual dimorphism involving dwarf males and the paired/non-paired configuration of the gonoducts (genital sacs). Furthermore, the data supports the sister group relationship of Echiuridae and Urechidae. These two families share the character of having anal chaetae rings around the posterior trunk as a synapomorphy. The analyses also suggest that deposit feeding is a basal feeding mode in echiurans and that filter feeding originated once in the common ancestor of Urechidae. Overall, our results contradict the currently accepted order-level classification, especially in that Echiuroinea is polyphyletic, and provide novel insights into the evolution of echiuran worms. -
Systematics, Phylogeny, and Taphonomy of Ghost Shrimps (Decapoda): a Perspective from the Fossil Record

Abstract Ghost shrimps of Callianassidae and Ctenochelidae are soft-bodied, usually heterochelous decapods representing major bioturbators of muddy and sandy (sub)marine substrates. Ghost shrimps have a robust fossil record spanning from the Early Cretaceous (~ 133 Ma) to the Holocene and their remains are present in most assemblages of Cenozoic decapod crustaceans. Their taxonomic interpretation is in flux, mainly because the generic assignment is hindered by their insufficient preservation and disagreement in the biological classification. Fur- thermore, numerous taxa are incorrectly classified within the catch-all taxonCallianassa . To show the historical patterns in describing fos- sil ghost shrimps and to evaluate taphonomic aspects influencing the attribution of ghost shrimp remains to higher level taxa, a database of all fossil species treated at some time as belonging to the group has been compiled: 250 / 274 species are considered valid ghost shrimp taxa herein. -

Severtzov Institute of Ecology and Evolution (RAS), Laboratory of Marine Invertebrates Ecology and Morphology, Leninsky Pr. 33, 129071 Moscow, Russia. E-mail: [email protected] ABSTRACT Although there have been numerous isolated studies and reports of symbiotic relationships of polychaetes and other marine animals, the only previous attempt to provide an overview of these phenomena among the polychaetes comes from the 1950s, with no more than 70 species of symbionts being very briefly treated. Based on the available literature and on our own field observations, we compiled a list of the mentions of symbiotic polychaetes known to date. Thus, the present review includes 292 species of commensal polychaetes from 28 families involved in 713 relationships and 81 species of parasitic polychaetes from 13 families involved in 253 relationships. When possible, the main characteristic features of symbiotic polychaetes and their relationships are discussed. Among them, we include systematic account, distribution within host groups, host specificity, intra-host distribution, location on the host, infestation prevalence and intensity, and morphological, behavioural and/or physiological and reproductive adaptations.

Shrimp Neotrypaea Californiensis to Intertidal Shell and Mud Habitats
MARINE ECOLOGY PROGRESS SERIES Published April 30 Mar Ecol Prog Ser l Effects of substrate selection and post-settlement survival on recruitment success of the thalassinidean shrimp Neotrypaea californiensis to intertidal shell and mud habitats Kristine L. Feldmanlr*,David A. ~rmstrongl,David B. ~ggleston'~",Brett R. ~umbauld~ 'School of Fisheries, Box 357980, University of Washington, Seattle, Washington 98195, USA 'Washington State Department of Fish and Wildlife, Willapa Bay Field Station, PO Box 190, Ocean Park, Washington 98640, USA ABSTRACT: We quantified recruitment of young-of-the-year (YOY)burrowing thalassinidean shrimp Neotrypaea californiensis to 2 habitats of differing structural complexity-epibenthic bivalve shell and bare mudflat-and examined how differential settlement and post-settlement predation influence patterns of YOY abundance. Local densities of shrimp were quantified prlor to construction of shell habitat in Grays Harbor estuary, Washington (USA). Subsequent recruitment of YOY shrimp to epiben- thic shell and bare mudflat was measured during a peak settlement pulse and 10 mo post-settlement. In addition, patches of sediment overlying shell within the shell plot ('subsurface shell') were sampled 10 mo post-settlement. Differential settlement in shell and mud habitats was quantified in field and laboratory experiments. We also examined predator-prey interactions between YOY Dungeness crabs Cancer magister and newly settled shrimp in shell habitat in a laboratory experiment in which prey consumption crab-' was quantified as a function of shrimp density. Results of our studies indicate that dense coverage of epibenthic shell applied to the intertidal site reduced recruitment of ghost shrimp. Epibenthic shell habitat had significantly fewer YOY shrimp than bare mudflat at peak settlement and 10 mo post-settlement, and significantly fewer shrimp than 'subsurface shell' at 10 mo post-settlement. -
