Predator-induced cloning in echinoid larvae, with reduced size a consequence of cloning, is a dramatic modification of development and a novel response to risks associated with prolonged planktonic development. Recent laboratory studies demonstrate that exposure to stimuli from predators (i.e., fish mucus) induces cloning in the pluteus larvae (plutei) of Dendraster excentricus. However, the timing and incidence of cloning and size reduction of unrelated conspecific plutei differed across… 
Abrupt Change in Food Environment Induces Cloning in Plutei of Dendraster excentricus
TLDR
Results indicate that a change in food concentration can induce cloning in plutei, and demonstrate that anterior autotomization does occur in 4- to 6-arm pluteo.
Why run and hide when you can divide? Evidence for larval cloning and reduced larval size as an adaptive inducible defense
TLDR
This study tested the hypothesis that the small size of predator-induced clones reduces vulnerability during encounters with planktivorous fish, and offered a new ecological context for asexual reproduction: rapid size reduction as a defense.
A Novel Report of Hatching Plasticity in the Phylum Echinodermata
TLDR
Plasticity in the timing and stage of hatching of embryos of the sand dollar Echinarachnius parma is reported in response to reductions in salinity, suggesting significant intraspecific variation in developmental responses to salinity.
Larval ecology of echinoids
Rudiment resorption as a response to starvation during larval development in the sea urchin Strongylocentrotus droebachiensis
TLDR
It is speculated that sea urchin rudiments might provide means of buffering development during unfavorable conditions and identify a developmental “window of opportunity” within which this can occur.
Ocean acidification induces budding in larval sea urchins
TLDR
It is shown that larvae of the purple urchin, Strongylocentrotus purpuratus, underwent high-frequency budding (release of blastula-like particles) when exposed to elevated pCO2 level, and the associated reduction in larval size is suggested.
The peril of the plankton.
TLDR
Recent advances in understanding the behavioral, chemical, and morphological defenses that larvae possess and assess their effectiveness in reducing the risk of predation indicate that marine invertebrate larvae possess a sophisticated suite of defensive phenotypes that have allowed them to persist in the life cycle of benthic invertebrates for eons.
Cloning and Selfing Affect Population Genetic Variation in Simulations of Outcrossing, Sexual Sea Stars
TLDR
Simulated variation in two simple models was consistent with high rates of cloning or selfing or both, and future models or analyses of genetic variation in similar study systems might benefit from simulation modeling to characterize possible contributions of cloning and selfing to Genetic variation in population samples.
Developmental Biology of the Sea Urchin and Other Marine Invertebrates
TLDR
This work focuses on the cultivation of Larvae of Marine Invertebrates and the management of Larval Settlement and Metamorphosis in the context of Sea Urchin Larvae.

Predators Induce Cloning in Echinoderm Larvae
TLDR
This research shows that larvae of the sand dollar Dendraster excentricus also clone in response to cues from predators, suggesting an advantage against visual predators.
Reduction in morphological plasticity in echinoid larvae: relationship of plasticity with maternal investment and food availability
TLDR
Comparisons among species showed that larvae developing from smaller eggs had a significantly higher plastic response to exogenous food than larvae developingFrom large eggs, and species with larger eggs will have reduced overall plasticity and growth trajectories similar to highly fed larvae from a species that exhibits plasticity.
Widespread cloning in echinoderm larvae
Widespread cloning in echinoderm larvae Asexual reproduction by free-living invertebrate larvae is a rare and enigmatic phenomenon and, although it is known to occur in sea stars and brittle stars,
Induced Settlement and Metamorphosis of Sand Dollar (Dendraster Ecentricus) Larvae in Predator-Free sites: Adult Sand Dollar Beds
TLDR
Dendraster excentricus larvae capable of metamorphosis presented with various sub- strates show a significant preference for adult-associated sand, which should result in increased larval and juvenile survival.
Feeding and Nonfeeding Larval Development and Life-History Evolution in Marine Invertebrates
TLDR
Many marine invertebrates have elaborate feeding larval forms whereas others, sometimes within the same taxon, have more direct development, and questions about the evolution and consequences of the life histories of these forms are raised.
Induced vertical migration in copepods as a defence against invertebrate predation
TLDR
The results show that crustacean zooplankton may be capable of flexible, predator-sensitive foraging and suggest a mechanism for rapid changes in migration patterns.
HETEROCHRONIC DEVELOPMENTAL PLASTICITY IN LARVAL SEA URCHINS AND ITS IMPLICATIONS FOR EVOLUTION OF NONFEEDING LARVAE
TLDR
Sea urchin larvae exposed to different amounts of food in the laboratory and in the field produced differences in timing of development of larval and juvenile structures, which suggests that developmental plasticity that is adaptive for feeding larvae also contributes to correlated and adaptive evolutionary changes in the transition to nonfeeding larval development.
Abundance of Food Affects Relative Size of Larval and Postlarval Structures of a Molluscan Veliger.
TLDR
Observations in larvae as disparate as oyster veligers and sea urchin plutei suggest that functionally similar examples of developmental plasticity in the growth of larval parts have evolved more than once and may be widespread.
