Chemical Mediation of Egg Capsule Deposition by Mud Snails

Journal of Chemical Ecology, 2002
Mud snails (Ilyanassa obsoleta = Nassarius obsoletus = Nassa obsoleta) deposit eggs in protective capsules on hard substrata in soft bottom environments. We studied sites of egg capsule deposition and snail movement responses to odors to determine if chemoreception plays a role in deposition site selection.

EGG COUNTING SNAILS

Journal of Experimental Biology, 2003
Laying eggs is hard work, and risky with the next generation's future invested in a single clutch. So snails only ovulate when the time and place is right. But how land snails control this costly process wasn't clear until Ronald Chase began investigating a branch of the intestinal nerve that ...

Lipoproteins of the egg perivitelline fluid ofPomacea canaliculata snails (Mollusca: Gastropoda)

The Journal of Experimental Zoology, 1996
The lipid and protein composition of the perivitelline fluid of the eggs of Pomacea canaliculata was investigated. Two lipoproteins (PV 1 and PV 2) and one lipoprotein fraction (PV 3) were detected for the first time in gastropods. They represent 57.0, 7.5, and 35.5% of the egg total proteins, respectively. PV 1 is a glyco-carotene-protein complex with

The Egg-Laying Behavior of the Pond Snail: Electrophysiological Aspects

1984
The ovulation hormone of the pond snail Lymnaea stagnalis is produced by the caudo-dorsal cells (CDCs) of the cerebral ganglia [1]. The CDCs secrete their products (see also Geraerts et al., this volume) during a 30 min period of repetitive spiking activity termed the afterdischarge [2].

The Eggs and Egg-Laying Habits of Some Midwestern Land Snails

Transactions of the Kansas Academy of Science (1903-), 1963
During the past few years laboratory populations of twenty-four species of Nebraska's land snails have been established as part of a continuing survey of the gastropod fauna of the state. Observations on the eggs and aspects of the reproductive activity of some of these gastropods are recorded here as a contribution to an area of the natural history of

Spontaneous and induced egg laying behavior of the pond snail,Lymnaea stagnalis

Journal of Comparative Physiology A, 1989
InLymnaea egg laying is initiated by the discharge of the neurosecretory caudodorsal cells (CDCs), which release an ovulatory hormone (caudodorsal cell hormone; CDCH) and other peptides. Egg laying is a complex behavioral pattern composed of various postures and action patterns. This paper describes the egg laying behavior of intact and freely behaving
