[5] After splitting, the brittle star may still be able to reproduce sexually but some fragments of the disc may have no gonads and thus be unable to spawn until regeneration is complete. La reproduction asexuée dont cette espèce est capable a probablement aidé sa conquête avec des effectifs faibles [17].

[4], Individual O. savignyi are either male or female, and they can reproduce either sexually or asexually. Sampling the brittle stars throughout the year resulted in finding that 48% of the individuals inspected were in the process of regeneration. Sexual reproduction involves the liberation of sperm and eggs into the sea and the development and eventual settlement of planktonic larvae. Clark, 1939; Ophiactis sulcata Kutscher & … Up to twenty individuals can be found clumped together in cavities in the base of the sponge, the area being so filled with the slime secreted by the sponge that the brittle stars can hardly move their arms. 2001. It occurs on mangrove swamp (Ref. Three tiny arms are beginning to regenerate. 800), and seagrass Halimeda (Ref. They turn up in reef tanks sometimes, and they're referred to as "micro brittle stars" in the hobby.

Ophiactis savignyi is benthic and resides inshore, on continental shelves, and continental slopes. The echinoderm fauna of Australia; it composition and origin. At certain times of the year, large females and males raise their disks off the surface, balance on their legs, and release sperm and eggs into the ocean. Reproduction and population dynamics of the fissiparous brittle star. They inhabit virtually all of the world's tropical and sub-tropical ocean habitats. In each sampling period, I hand-collected sponges, finely dissected each, and removed all brittle stars residing within the sponge (hereafter termed a "popula-tion"). It occurs in the tropical and subtropical parts of all the world's oceans and is thought to be the brittle star with the most widespread distribution. When fission happens, the brittle star breaks down the middle of its disk to make two identical 3-armed halves. It comprised more than 50% of individuals found in the sponges, and it is also the only endobiont that was found in … When several references are cited, they may give conflicting information on the status.

Density, size structure and reproductive characteristics of fissiparous brittle stars in algae and sponges: evidence for interpopulational variation in levels of sexual and asexual reproduction. Small, immature individuals (disc diameter under 4 millimetres (0.16 in)) usually have six arms and can split themselves in two and then regenerate the missing parts of the disc and arms, often ending up with five arms. P:941-950. It is present in the western Indo-Pacific region, the eastern Pacific Ocean, and on both sides of the Atlantic Ocean. These brittle stars often seem to have broken or partly regenerated arms. Habitat et répartition Ophiures ...
