Ophidiaster granifer Lütken is a small cryptic coral reef asteroid found in the Indo-West Pacific. Its mode of reproduction, shown by aquarium observations and gonad histology, is parthenogenetic. This is the first confirmation of natural parthenogenesis in the phylum Echinodermata, despite many studies showing artificial parthenogenesis in echinoderms. Populations of O. granifer from Micronesia, New Guinea and the Great Barrier Reef consisted only of females: no testes or spermatogenesis were… 
Larval and life-cycle patterns in echinoderms
TLDR
It is concluded that it is the ecological and functional demands on larvae which impose limits on developmental evolution and determine the associations of larval types and life-cycle character states that give rise to the developmental patterns that the authors observe in echinoderms.
Brooding and the evolution of parthenogenesis: strategy models and evidence from aquatic invertebrates
TLDR
It is suggested that internally fertilized animals that brood their young may be more susceptible to invasion by parthenogenetic mutants, because brooders could establish ‘selective arenas’ in which developmentally defective embryos are competitively displaced.
Reproductive biology and early life history of the crown-of-thorns starfish
TLDR
This chapter reviews the unique features of A. planci reproductive biology and early life history that make it predisposed to population fluctuations and discusses factors that regulate gametogenesis, fecundity, spawning, fertilization, larval development, and post-settlement survival.
Pale biological implications of some Upper Ordovician juvenile asteroids (Echinodermata)
TLDR
The skeleton of well-preserved juveniles of the Late Ordovician species Promopalaeaster finei is similar in fundamental ossiclar arrangement to one of these patterns, suggesting continuity of developmental sequence, and axillary development is linked to the common absence of actinal ossicles from Paleozoic species.
Life Cycle Evolution in Asteroids: What is a Larva?
TLDR
It is argued that the ancestral asteroid life cycle involved pelagic larval development with both bipinnarian and brachiolarian stages and six types of evolutionary transitions in development that can account for the diversity of larval forms and developmental patterns in starfish.
Patterns and Drivers of Egg Pigment Intensity and Colour Diversity in the Ocean: A Meta-Analysis of Phylum Echinodermata.
TLDR
Examining an unprecedented combination of egg colours/intensities and reproductive strategies sheds new light on the role and drivers of egg pigmentation, drawing parallels with theories developed from the study of more derived vertebrate taxa.
The pelagic propagule’s toolkit: An exploration of themorphology, swimming capacity and behaviour of marineinvertebrate propagules
TLDR
The PhD research examines the variation in echinoderm propagule morphology, locomotion, and behaviour during ontogeny, and in response to abiotic cues to provide a framework to assess the adaptive value of pelagic propagules to benthic animals, to examine the trade-offs of complex lifehistory strategies, and to enhance modeling of larval dispersal in the marine environment.
On the advantages and disadvantages of larval stages in benthic marine invertebrate life cycles
TLDR
The prominence of larval development in modern life cycles may reflect difficulties in losing larvae from invertebrate life cycles more than selection for their retention.
Diseases of Echinodermata II: Agents metazoans (Mesozoa to Bryozoa)
TLDR
Echinoderms generally act as second intermediary host for trematodes; the latter are known mostly from echlnoids and ophiuroids which constitute the most frequent echinoderm prey for fishes.
Long-term changes in reproductive patterns of the holothurian Oneirophanta mutabilis from the Porcupine Abyssal Plain
TLDR
It is suggested that the superabundance of certain megafaunal species on the abyssal seafloor affected the availability of trophic resources for O. mutabilis, leading to the changes in its reproductive effort.

Divide or broadcast: Interrelation of asexual and sexual reproduction in a population of the fissiparous hermaphroditic seastar Nepanthia belcheri (Asteroidea: Asterinidae)
TLDR
Sexual reproduction in an intertidal population of Nepanthia belcheri (Perrier) at Townsville, Queensland, Australia, was very subordinate to fission as the means of recruitment, as a functionally dioecious population may develop from one larva settling in a new locality.
Coral-Reef Asteroids of Guam
TLDR
In spite of the great diversity of adult structure, habitat, behavior, and population densities, many common asteroids produce larvae with similar structure and behavior, suggesting that environmental pressure to reduce larval populations may work in a similar manner among many species, resulting in stereotyped larval forms.

TLDR
A survey of larvae in spiralian phyla indicates that for several reasons the spiralians have been more flexible in acquiring new planktotrophic larval forms, and some of the reasons for these differences are indicated.
Early Life History of the Giant Clams Tridacna crocea Lamarck, Tridacna maxima (Roding), and Hippopus hippopus (Linnaeus)
TLDR
Growth rates increase sharply after the acquisition of zoo xanthellae and after 50 days for H. hippopus, which may be stimulated to spawn by the addition of macerated gonads to the water.
Saponins in eggs and larvae of A canthaster planci (L.) (Asteroidea) as chemical defences against planktivorous fish
TLDR
The saponins in eggs and larvae of A. planci are at levels detectable by, and unpalatable to, planktivorous fish and they account, at least in part, for the observed rejection of these early developmental stages by planktIVorous fish.

Lunar reproductive rhythms have been part of fishermen's lore since ancient times. Many such rhythms seem to be more fancy than fact, but one was described in some detail by H. Monroe Fox in 1923. He
Asexual reproduction as a means of population maintenance in the coral reef asteroid Linckia multifora on Guam
TLDR
Individuals of the comet phase represent the highest percentage for population samples collected throughout the year from several sites on Guam, indicating a continuous asexual reproduction through which populations of L. multifora are being maintained.
