== Distribution and habitat ==
''Stichopus chloronotus'' is native to the Indo-Pacific. Its range extends from the [[Red Sea]] and the East Coast of Africa, through [[Madagascar]], the [[Seychelles]], the [[Comores]] and [[Réunion]]<ref name=WoRMS/> to Australia, Indonesia, China, Japan, [[Guam]], [[Fiji]], [[Tonga]] and [[Samoa]].<ref name="iucn status 20 November 2021" /> It lives on reefs, but can also be found on rubble located on the outer reef flats<ref name=MSIP/> at depths down to about {{convert|12|m|0|abbr=on}}.<ref name=Florent/>
== Biology ==
''Stichopus chloronotus'' is a [[detritivore]] and sifts through the sediment on the seabed with its tentacles and feeds on [[detritus]] and other organic matter including plant and animal remains, bacteria, protozoa, diatoms and faeces.<ref name=FAO>{{cite web |url=ftp://ftp.fao.org/docrep/fao/011/i0375e/i0375e03.pdf |title=Population status, fisheries and trade of sea cucumbers in Asia |author=Poh-Sze Choo |date= |work= |publisher=FAO |accessdate=2012-06-09}}</ref> In the process it swallows a lot of sand and plays an important part in churning up and aerating the seabed.<ref>[https://books.google.com/books?id=myJFAAAAYAAJ Marine Biology Papers, Volume 19] Carnegie Institution of Washington. Tortugas Laboratory, Carnegie Institution of Washington. 1924, p 34</ref>
''Stichopus chloronotus'' can reproduce asexually by undergoing [[Fission (biology)|transverse fission]], forming two new individuals which each regenerate the missing parts. It can also reproduce sexually.<ref name="iucn status 20 November 2021" />

''Stichopus chloronotus'' is gathered for human consumption across much of its range. Although not one of the most important species for this purpose, it resembles the much-favoured Japanese sea cucumber ''[[Apostichopus japonicus]]'' and is increasingly being caught in some areas as supplies of that species dwindle. This species has a widespread distribution and is common in many parts of its range so the [[IUCN]] lists it as being of "[[Least Concern]]".<ref name="iucn status 20 November 2021" /> It is also known to occur in several protected areas, including the [[Dr. K.K. Mohammed Koya Sea Cucumber Conservation Reserve]] in [[Lakshadweep]], [[India]].<ref name="Mohammednowshad2021">{{cite journal|last1=Mohammednowshad|first1=B.|last2=K.K.|first2=Idreesbabu|last3=S.|first3=Sureshkumar|title=Habitat wise variability in the diversity of sea cucumbers in Lakshadweep Archipelago, North-Western Indian Ocean|date=4 May 2021|orig-date=16 June 2020|journal=Regional Studies in Marine Science|volume=41|publisher=Elsevier|doi=10.1016/j.rsma.2021.101805|url=https://www.sciencedirect.com/science/article/pii/S2352485521001973|access-date=18 May 2024}}</ref>
