The horned sea star (Protoreaster nodosus) is relatively common in the Indo-Pacific region, but there is little information about its biology. This study of the population biology of P. nodosus was carried out in Davao Gulf, The Philippines (7°5′N, 125°45′E) between September 2006 and May 2008. Protoreaster nodosus was found in sand and seagrass dominated habitats at a mean density of 29 specimens per 100 m2 and a mean biomass of 7.4 kg per 100 m2, whereas a significantly lower density and… 
Ontogenetic habitat shift, population growth, and burrowing behavior of the Indo-Pacific beach star, Archaster typicus (Echinodermata; Asteroidea)
This is one of the first studies to document an ontogenetic habitat shift for sea stars and provides new biological information as a basis for management of harvested A. typicus populations.
Population ecology, reproduction, and locomotion of the sand dollar Sculpsitechinus auritus (Echinodermata: Echinoidea) in the Gulf of Suez, northern Red Sea
The epibiotic brittle star Ophiodaphne scripta was found on >67 % of the sand dollars and its frequency was significantly higher between September and November coinciding with the onset of S. auritus’s spawning period.
Growth and reproductive biology of the sea star Astropecten aranciacus (Echinodermata, Asteroidea) on the continental shelf of the Catalan Sea (northwestern Mediterranean)
Investigation of the growth and reproductive biology of the sea star Astropecten aranciacus revealed that spawning likely started in March, coinciding with the spring phytoplankton bloom and the increase in sea water temperature, and extended until June–July.
Spatial distribution patterns, abundance and reproductive effort of the starfish Echinaster (Othilia) paucispinus along an environmental gradient in a Caribbean mangrove ecosystem
It seems that the population of E. (O.) paucispinus at Laguna de La Restinga is governed by pre-settlement processes, rather than by environmental variability along the gradient.
Size distribution of individuals in the population of Asterias amurensis (Echinodermata: Asteroidea) and its reproductive cycle in China
The reproductive characteristics of sea star were most likely affected by the shellfish mariculture in Yantai coastal waters, and the gonad index (GI) and pyloric caeca index (PCI) tended to show a negative relationship.
Synchronized broadcast spawning by six invertebrates (Echinodermata and Mollusca) in the north-western Red Sea
The observations presented here provide relevant information on broadcast spawning of non-coral invertebrate taxa in the Red Sea, where spawning is considerably less well documented than in other tropical geographical regions such as the Indo-Pacific and Caribbean.

A. angulatus is intermediate among species which exhibit the extremes of life history strategies, that is, those which grow very rapidly and may live just two years or less and those with very slow growth rates and which may live for decades.
An ecological survey of the abundance and diversity of benthic macrofauna in Indonesian multispecific seagrass beds
Seagrasses are one of the most productive ecosystems in coastal areas and support a wide variety of associated fauna. The tropical Indo-Pacific region is considered to have the highest diversity of


Abundance, spatial distribution, and size structure of the sea star Protoreaster nodosus in Palau, with notes on feeding and reproduction
Manipulations of density and spatial distribution showed that sea stars reestablish pre-manipulation densities and nearest-neighbor spacing within 2-5 d, suggesting these sea stars are important consumers and bioturbators in sedimentary habitats.
Annual reproductive cycle, spatial distribution, abundance, and size structure of Oreasterreticulatus (Echinodermata: Asteroidea) in Bocas del Toro, Panama
The structure, distribution, and population abundance of Oreasterreticulatus (Linnaeus, 1758) in 47,157 ha of shallow-water habitat in the archipelago of Bocas del Toro, Panama, were assessed from May to October 2000 and provide a useful baseline for management of local populations in the face of an increasing harvest for the aquarium trade and as souvenirs.
Genetic consequences of long larval life in the starfish Linckia laevigata (Echinodermata: Asteroidea) on the Great Barrier Reef
Gene flow between populations of the asteroid Linckia laevigata (Linnaeus) was investigated by examining over 1000 individuals collected from ten reefs throughout the Great Barrier Reef (GBR),
Abundance, spatial distribution, and size structure of populations of Oreaster reticulatus (Echinodermata: Asteroidea) on sand bottoms
Three populations of Oreaster reticulatus (Linnaeus, 1758) inhabiting shallow-water (<4 m) seagrass habitats in the Grenadines (West Indies, Caribbean Sea) were associated predominantly with beds of
Multi-species spawning of corals in north-western Philippines
Multi-species coral spawning was observed during all of the months of observation except in April 2007 and further studies are required to establish the extent of spawning at other times of the year and the reproductive patterns of corals elsewhere in the Philippines.
Mass spawning by the sea urchin Evechinus chloroticus (Echinodermata: Echinoidea) in a New Zealand fiord
A mass synchronous spawning of the sea urchin Evechinus chloroticus (Valenciennes) was observed in situ in Doubtful Sound, a large New Zealand fiord on 27 January 1994 and marked a 42 to 50% decrease in gonad indices and resulted in a widespread, dense cohort of larvae within the fiord.
Population impacts of collecting sea anemones and anemonefish for the marine aquarium trade in the Philippines
Analysis of catch records obtained from collectors over a four-month period in the vicinity of Cebu, Philippines, showed that anemonefish and anemones comprised close to 60% of the total catch and densities were significantly lower in exploited areas than in protected areas.
