WebAdelphophagic embryos usually develop directly into juveniles, bypassing the free-living larval stage. This results in large benthic hatchlings with low dispersal ability compared to those species with planktotrophic larvae. In this respect adelphophagic species are ecologically similar to species with direct development from large eggs. Webadelphophagic gastropods. In families were adelphophagy is common it appears to have arisen multiple times. For example in calyptraeid gastropods phylogenetic analysis …

Three females (of 40) “switched” between adelphophagy and planktotrophy either between sequential broods or by producing both types of capsules in a single brood.

The third whelk species was the adelphophagic Haustrum scobina, which produces multiple WebDec 1, 2014 · In adelphophagic development, there is also the potential for high variability in offspring size because egg size and larval size are uncoupled which may facilitate sibling competition among larvae (Collin and Spangler, 2012, Kamel et al., 2010). As such, emerging adelphophagic larvae that are smaller than their larger siblings may have … horse riding tales für laptop
