Reproduction and development of marine invertebrates
TLDR
Comprehensive in scope, this book treats all levels of biological organization, from the molecular level to communities of organisms, and includes new information on the role of hydrodynamics to aid in the understanding of larval dispersal and settlement. Expand
The life history of Syndisyrinx franciscanus, a symbiotic turbellarian from the intestine of echinoids, with observations on the mechanism of hatching
TLDR
Experiments revealed that hatching is induced by some property of the intestinal fluids of the urchins, and that the changes in the capsule wall are mediated by the embryos, perhaps by the secretion of a hatching enzyme. Expand
REPRODUCTION OF ANOPLODIUM HYMANAE, A TURBELLARIAN FLATWORM (NEORHABDOCOELA, UMAGILLIDAE) INHABITING THE COELOM OF SEA CUCUMBERS; PRODUCTION OF EGG CAPSULES, AND ESCAPE OF INFECTIVE STAGES WITHOUT
TLDR
Anoplodium hymanae, a member of the turbellarian family Umagillidae, parasitizes the holothuroid Stichopus californicus along the northeastern Pacific coast and continues to grow after attaining reproductive maturity. Expand
Anoplodium hymanae sp. n., an umagillid turbellarian from the coelom of Stichopus californicus, a Northeast Pacific holothurian
Anoplodium hymanae sp. n., a symbiont of the holothurian Stichopus californicus, is described from specimens collected near San Juan Island, Washington, U.S.A. Worms of this species have a singleExpand
Ultrastructure of Meelsvirus: A nuclear virus of arrow worms (phylum Chaetognatha) producing giant “tailed” virions
TLDR
The discovery of a new prototype of giant virus infecting epidermal cells of the marine arrow worm Adhesisagitta hispida, which is postulate that transmission to new hosts occurs by rupture of protruding virion-filled nuclei when infected arrow worms mate. Expand
The diet of three species of umagillid neorhabdocoel turbellarians inhabiting the intestine of echinoids
Three species of umagillid turbellarians were found to have different nutritional relationships with their echinoid hosts: Syndisyrinx franciscanus ingests host intestinal tissue and ciliates thatExpand
Egg capsules of a parasitic turbellarian flatworm: Ultrastructure of hatching sutures
TLDR
Transmission electron microscopy discloses that hatching sutures traverse the entire thickness of the capsule wall of Syndisyrinx franciscanus, an intestinal parasite of sea urchins, and the outside of some capsules is partially covered by a thin, electron‐dense material. Expand
Contrasting modes of reproduction in the polymorphic symbiotic flatworm Syndesmis dendrastrorum (Turbellaria Neorhabdocoela: Umagillidae)
TLDR
Syndesmis dendrastrorum, an endosymbiont of the northeastern Pacific sand dollar, was previously described as having three morphs that differ in the number and arrangement of the gonads, but these newly recognized differences in reproductive biology raise the possibility that it consists of more than one species. Expand
Ultrastructure of transrectal coelomoducts in the sea cucumber Parastichopus californicus (Echinodermata, Holothuroida)
TLDR
It is discussed that perivisceral coelomoducts of holothuroids function in regulating coelomic volumes in the sea cucumber Parastichopus californicus. Expand
