Found in shallow waters, rarely in depths of more than 10 m; mostly on inner reef flats of fringing and lagoon-islets reefs, coastal areas under terrigenous influence, and near mangroves.
Bulletin of the British Museum (Nature History). Holothuria edulis, commonly known as the edible sea cucumber or the pink and black sea cucumber, is a species of echinoderm in the family Holothuriidae.It was placed in the subgenus Halodeima by Pearson in 1914, making its full scientific name Holothuria (Halodeima) edulis. ; hence it is highly plausible that more sea cucumber species are yet to be found 7
Holothuria scabra is een zeekomkommer uit de familie Holothuriidae. It is generally well known that adult Holothuria (Metriatyla) scabra has many associations with various other organisms – including gastropods, crustaceans, worms and fish 25 . Hollertz K. and Duchêne J.-C. 2001. In particular, please adhere to copyright law. Zoology.18(4): 119-170. This makes them a key species for aquaculture production, where the species flourishes; one of the only tropical holothurian species to do so.

Muthiga, J.A. The presence of an endangered and economically valuable species of sea cucumber, Holothuria (Metriatyla) scabra Jaeger, 1833, was investigated in the Alqurm Wa Lehhfaiiah Protected Area near the city of Kalba in the Emirate of Sharjah. According to studies conducted to observe mature gonopores between male and female Holothuria (Metriatyla) scabra, the mature female **gonads** were reported with two varying forms – either translucent, or brown tubules of even length and thickness with little white spots (oocytes), while the mature male gonads are observed to have lengthy white beaded filaments of even length and thickness25
This starts when the adults spawn. In recent years Australia, Indonesia, New Caledonia, Maldives, Solomon Islands and Vietnam have successfully cultured H. scabra using the same technology, and now culture other species. They do have a tolerance for lowered salinity, down to 20 ppt, such as that found in brackish water. . , 10
Holothuria scabra 2. To shorten the hatchery rearing phase, ocean nursery systems like floating hapa nets have been used with good prospects but with limitations during rough sea conditions. . It was placed in the subgenus Metriatyla by Rowe in 1969 and is the type species of the subgenus. Furthermore, the CMBS study did not include sites from our Southern shores, ; hence it is highly plausible that more sea cucumber species are yet to be found, .

Turici. The economically valuable sea cucumber,Holothuria scabra (sandfish) is distributed throughout the Indo-Pacific in subtidal estuarine habitats and exploited heavily for markets in the Asia-Pacific region.
According to Hamel et al. URL: Tuwo, A., Tresnati, J. Key habitat characteristics critical to the survival, growth and daytime burying behaviour of juvenile sand- fish released into the wild were rela- tively shallow depth (0.3 to 1.5 m), intermediate seagrass cover (30 to 50%), fine sand grains (~130 μm) and high organic C content (>1.9%) of the sediments.

The anus of the Holothuria (Stauropora) fuscocinerea has a striking dark brown coloration while the anus of Holothuria (Metriatyla) scabra does not. All of them inhabit the ocean, although some inhabit shallow waters and others live in the depths of the ocean. Such a species delimitation concept veers away from biological species concepts which require reproductive isolation; the species delimitation concept used here seems to draw similarity with the phylogenetic species concept by Wheeler and Platnick (2000) instead, which focuses on describing species through their unique combination of fixed character states.

PHYLUM : ECHINODERMATA CLASS : HOLOTHUROIDEA Family : Holothuridae Common name : Sea cucumber / Kadal attai Habitat : Shallow sandy bottoms Description: Firm, loaf-shaped body with blunt ends and prominent wrinkles on the upper side. Sandfish are harvested and processed into "beche-de-mer" and eaten in China and other Pacific coastal communities. Massin, C., Uthicke, S., Purcell, S.W., Rowe, F.W.E. Battaglene (1999) has observed that the Holothuria (Metriatyla) scabra takes 14 days to develop into juveniles on 5-10mm in culture conditions 30
It is a medium-sized species (to 400 mm), somewhat flattened, and firm to pliable. In an experiment to test predation, small juveniles of 20-70mm released on sand near coral reefs are predated by a range of fish species (includes Balistidae, Lethrinidae and Nymipteridae); the same experiment done on seagrass beds observed no predation.
