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, it has not been detected in other echinoderms despite more than a century of intensive study. Here we describe spontaneous larval cloning in three species from two more echinoderm classes: a sea cucumber (Holothuroidea), a sand dollar and a sea urchin (Echinoidea). Larval cloning may therefore be an ancient ability of echinoderms and…

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.
Culturing echinoderm larvae through metamorphosis.
TLDR
To facilitate broader studies of post-embryonic echinoderms, the collective experience of echinoderm embryology labs is provided, with suggestions to try and pitfalls to avoid.
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.
Discovery of Adults Linked to Cloning Oceanic Starfish Larvae (Oreaster, Asteroidea: Echinodermata)
Two juvenile specimens of a new species of Oreaster were collected at Parque Nacional Arrecife Alacranes and Triángulos Oeste in the southern Gulf of Mexico. DNA of mitochondrial loci identifies them…
Sea Urchin Larvae as a Model for Postembryonic Development.
TLDR
There is strong evidence emerging that endocrine signaling, immunity, and host-microbe interactions play major roles in larval development and physiology, and future research should take advantage of sea urchin larvae as a model to study these processes in more detail.
Evolutionary crossroads in developmental biology: sea urchins
TLDR
Echinoderms have contributed significantly to the understanding of many developmental mechanisms, including those that govern the structure and design of gene regulatory networks, those that direct cell lineage specification, and those that regulate the dynamic morphogenetic events that shape the early embryo.
Full allogeneic fusion of embryos in a holothuroid echinoderm
TLDR
The discovery of natural chimaerism in a unitary deuterostome that possesses large externally fertilized eggs provides a framework to explore key aspects of evolutionary biology, histocompatibility and cell transplantation in biomedical research.
Predator-Induced Larval Cloning in the Sand Dollar Dendraster excentricus: Might Mothers Matter?
  • D. Vaughn
  • Biology, Medicine
    The Biological Bulletin
  • 2009
TLDR
The hypothesis that cloning in D. excentricus plutei is maternally influenced by mothers is tested and reduced larval size was a uniform response to fish mucus and did not indicate an effect of mothers.
The Use of Larval Sea Stars and Sea Urchins in the Discovery of Shared Mechanisms of Metazoan Whole-Body Regeneration
TLDR
Interrogations in two highly studied echinoderms, the sea urchin and the sea star, have provided knowledge of tissue and whole-body regeneration at various life stages, as well as a potential new system for understanding regenerative mechanisms in a basal deuterostome.
The invertebrate deuterostomes: an introduction to their phylogeny, reproduction, development, and genomics.
TLDR
Genomic resources are being developed from a variety of these organisms because of the utility of invertebrate deuterostomes for developmental analysis and their close phylogenetic relationship to vertebrates.

Cloning by Ophiuroid Echinoderm Larvae.
  • E. Balser

TLDR
Asexually produced secondary larvae of O. aculeata and an unidentified species of ophiuroid undergo metamorphosis, settle to the benthos, and initiate a tertiary larval generation, indicating that cloned larvae could be added to the population as long as environmental conditions could support a planktonic existence.
Identification of Asteroid Genera With Species Capable of Larval Cloning
TLDR
This study is the first to identify field-collected cloning asteroid larvae, and provides evidence that larval cloning is phylogenetically widespread within the Asteroidea.

  • W. Jaeckle

  • 1994
TLDR
Sea star larvae (Echinodermata: Asteroidea), collected from the subtropical Northwest Atlantic Ocean, exhibited three distinct modes of asexual reproduction, which provide a common mechanism to increase the length of larval life and amplify the number of individuals.
Studies of the Development and Larval Forms of Echinoderms
TLDR
It is almost as though there were an alternation of generations, as though the larva bore the young echinoderm as a mother bears a child; and Dr. Mortensen suggests that an ophiurid larva, which, after dropping the young brittle-star, proceeds to reconstitute its own body, and continues life as an independent individual.
Larval budding, metamorphosis, and the evolution of life‐history patterns in echinoderms
TLDR
The oral surface and mouth of juvenile asteroids and echinoids with indirect devel- opment forms on the lower left side of the larval body, thus establishing a new axis of body symmetry, and whether this also explains the position of the juvenile rudiment in echinoid is a more complex question.
Effects of food concentration and availability on the incidence of cloning in planktotrophic larvae of the sea star Pisaster ochraceus.
TLDR
The authors' experiments indicate that cloning generally occurs after larvae have attained asymptotic body length and only when food is abundant and of high quality, and production of clones under optimal conditions of temperature and food may serve to increase larval populations when the environment is most conducive to larval growth.
Echinoderm Larvæ and their Bearing on Classification
TLDR
The article consists of a review of Dr. Mortensen's work entitled “Studies of the Development and Larval Forms of Echinoderms,” and in the course of the article Dr. Bather quotes with apparent approval some remarks of Dr Mortensen to which I desire to take the strongest exception.
Evolution of the chordate body plan: new insights from phylogenetic analyses of deuterostome phyla.
TLDR
The nesting of the pterobranchs within the enteropneusts dramatically alters the view of the evolution of the chordate body plan and suggests that the ancestral deuterostome more closely resembled a mobile worm-like enteropNEust than a sessile colonial pterOBranch.
