This study examines the reproductive cycle, the mechanism of male-on-female pairing behavior and the spawning behavior of Archaster typicus Müller et Troschel. Field studies were conducted in the intertidal zone of the sand beaches at Penghu, Taiwan (23 32′N; 119 33′E) at ebb-tide in 1984 and 1985. The pairing behavior of A. typicus is a reproductive behavior which leads to simultaneous spawning, increasing the probability of fertilization. As the breeding season approaches, sea stars… 
Mating behavior of a brooding Antarctic asteroid, Neosmilaster georgianus
Spawning behavior and male-female superposition of Neosmilaster georgianus, a common brooding asteroid, were observed both in the field and the laboratory at Palmer Station, Antarctica, during the austral spring of 1991, marking the first reported instance of aggregative spawning in an Antarctic echinoderm.
Synchronous aggregated pseudo-copulation of the sea star Archaster angulatus Müller & Troschel, 1842 (Echinodermata: Asteroidea) and its reproductive cycle in south-western Australia
Mass individual pairing or pseudo-copulation of the sea star Archaster angulatus was observed in November and December 2009, suggesting a late-spring/summer spawning period for this species on the west coast of Australia, and Histological sections of gonads confirmed that sea stars are in peak reproductive condition in October and November and are fully spent by January.
Reproductive pattern in the brooding and broadcasting sea star Pteraster militaris
The reproductive cycle of a population of P. militaris from the northwest Atlantic Ocean was examined, and body component and maturity indices, gonad histology and response to 1-methyladenine indicate that females in the population have a continuous breeding season, with a slight decrease in intensity in the spring.
Gametogenesis and reproductive behavior in the echinoid Lytechinus variegatus
The data suggest that numerous small scale spawning events take place during an extended reproductive season and that intraspecific encounters occur during this season entirely by chance.
Prespawning Behavior, Spawning, and Development of the Brooding Starfish Leptasterias polaris.
The brooding behavior in L. polaris serves mainly to keep the eggs clean, healthy, and protected against predation, suggesting that the embryos develop at the same rate even when not brooded.
Selfing in Parvulastra exigua: an asterinid sea star with benthic development
Mixed mating, pseudocopulation during egg laying and developmental success of self-fertilized embryos may contribute to the ecological success of P. exigua and might influence population genetic structure and would facilitate establishment of founder populations by a small number of migrants.
Size at maturation, sex differences, and pair density during the mating season of the Indo-Pacific beach star Archaster typicus (Echinodermata: Asteroidea) in the Philippines
Mating of the relatively common sea star, Archaster typicus, provides an excellent opportunity to study maturation processes and behavioral differences between males and females, since monomorphism
Sex‐Specific Spawning Behavior and Its Consequences in an External Fertilizer

The results show that sex differences in spawning timing of marine invertebrates can be explained on the basis of the differential costs and benefits of spawning out of synchrony with the other sex and that the result of sexual selection on external fertilizers may be behavioral rather than morphological differentiation of the sexes.
Paternity analysis in the Antarctic brooding sea urchin Abatus nimrodi. A pilot study
This pilot study analysed a brooding female and her offspring with dominant molecular markers—RAPD (Random Amplified Polymorphic DNA) and established that each cohort present in the brooding pouches originated from at least two distinct father genotypes.
Depth-related shift in life history strategies of a brooding and broadcasting deep-sea asteroid
This study of H. lisa provides the first evidence of lecithotrophy in a seasonally breeding deep-sea echinoderm and of brooding in aDeep-sea asteroid.


The reproductive biology of Plutonaster Bifrons, Dytaster Insigns and Psilaster Andromeda (Asteroidea: Astropectinidae) from the Rockall Trough
Examination of the reproductive biology of three closely related sympatric astropectinid asteroidshas revealed two distinct reproductive strategies. In Plutonaster bifrons and Dytaster insignis the
The Reproductive Biology of the Deep-Sea Asteroid Bathybiaster Vexillifer
Although the seasonally reproducing asteroids show a wide variety of reproductive strategies, from planktotrophic larvae to direct development, they all occur in relatively shallow water and are thus subject to the seasonal fluctuations of the physico-chemical environment.

The results indicate that production of zygotes could be much less than production of eggs, unless adults aggregate and spawn synchronously, countering dilution of sperm by currents.
Studies of avoidance reactions in several species of Predatory British Seastars (Echinodermata: Asteroidea)
An intra-speciesavoidance was observed in C. papposus and the function and significance of this behaviour is discussed in relation to the inter-species avoidance reactions.
Interference and aggregation: Close encounters of the starfish kind
C. papposus interfered with A. rubens in the presence of a common food source and prevented the latter from aggregating due to interspecific avoidance resulting from encounters, which may enhance access to food for C. p apposus.
