Feeding by a “nonfeeding” larva: uptake of dissolved amino acids from seawater by lecithotrophic larvae of the gastropod Haliotis rufescens
Larvae of the red abalone (Haliotis rufescens Swainson) are functionally incapable of capturing particulate foods. The aim of this study was to determine whether these larvae could acquire energyExpand

Growth and Energy Imbalance During the Development of a Lecithotrophic Molluscan Larva (Haliotis rufescens)
Larvae of the gastropod Haliotis rufescens are classified as “?�nonfeeding” because they cannot cap ture particulate foods. However, for only 1out of5 inde pendent cultures was a net decreaseExpand

Rates of energy consumption and acquisition by lecithotrophic larvae of Bugula neritina (Bryozoa: Cheilostomata)
Lecithotrophic larvae of the cheilostome bryozoan, Bugula neritina (L.), lose metamorphic competence 12 to 24 h after release from the maternal zooid. The high respiration rate of newly releasedExpand

Identification of Asteroid Genera With Species Capable of Larval Cloning
Asexual reproduction in larvae, larval cloning, is a recently recognized component of the complex life histories of asteroids. We compare DNA sequences of mitochondrial tRNA genes (Ala, Leu, Asn,Expand

Ontogenic Changes in the Rates of Amino Acid Transport from Seawater by Marine Invertebrate Larvae (Echinodermata, Echiura, Mollusca)
Transport rates of amino acids were deter mined for larvae of different ages of the echiuran worm Urechis caupo, the gastropod Haliotis ruftscens, the bi valve Crassostrea gigas, and the sea urchinExpand

Comparison of eggshell porosity and estimated gas flux between the brown-headed cowbird and two common hosts
Th e brown-headed cowbird Molothrus ater is a brood-parasite that lays eggs in nests of a wide range of host species, including the closely-related red-winged blackbird Agelaius phoeniceus and theExpand

Amino Acid Uptake and Metabolism by Larvae of the Marine Worm Urechis caupo (Echiura), a New Species in Axenic Culture.
Axenic (bacteria-free) larval cultures of the marine echiuran worm, Urechis caupo, were reliably obtained by aseptically removing gametes directly from the gamete storage organs. Trochophore larvaeExpand

Size and Organic Content of Eggs of Marine Annelids, and the Underestimation of Egg Energy Content by Dichromate Oxidation
Dichromate oxidation is a simple technique that is often used to estimate the energy content of eggs in studies of marine invertebrate life histories (1). We used this method to measure the energyExpand
