Neocrinus decorus is a species of stalked crinoid, or sea lily, in the family Isocrinidae.{{Cite web|url=http://www.marinespecies.org/aphia.php?p=taxdetails&id=422450|title=WoRMS - World Register of Marine Species - Neocrinus decorus (Thomson, 1864)|website=www.marinespecies.org|access-date=2019-04-13}}
Distribution
The species lives on hard substrates (such as on lithoherm ridges) at depths of {{Convert|420 to 1219|m|ft}}, throughout the Caribbean Sea. It has been found off the coast of Venezuela, Honduras, the Dominican Republic, the Lesser Antilles, and the Gulf of Mexico.{{cite web |last1=Messing |first1=Charles G. |title=Dark Hilltop Gardens |url=https://oceanexplorer.noaa.gov/explorations/09bioluminescence/background/messing/messing.html |website=NOAA Ocean Explorer |publisher=National Oceanic and Atmospheric Administration (NOAA) |access-date=2 July 2024}}{{Cite web|url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=153363|title=Fossilworks: Neocrinus decorus|website=fossilworks.org|access-date=17 December 2021}}{{Cite web|url=https://www.gulfbase.org/species/neocrinus-decorus|title=Neocrinus decorus {{!}} GulfBase|website=www.gulfbase.org|access-date=2019-04-13}}{{cite web |title=Neocrinus decorus (Thomson, 1864) |url=https://www.marinespecies.org/aphia.php?p=taxdetails&id=422450 |website=WoRMS |publisher=World Register of Marine Species |access-date=2 July 2024}}{{cite web |title=Neocrinus decorus |url=https://www.st.nmfs.noaa.gov/nauplius/media/copepedia/taxa/T4123432/index.html |website=COPEPEDIA |publisher=National Oceanic and Atmospheric Administration (NOAA) |access-date=2 July 2024}}
Biology
Neocrinus decorus are epibenthic and may form aggregations in certain locales. Like other crinoids, they are suspension feeders, filtering out organic material and plankton that the current brings to their outstretched arms (the "filtration fan").{{cite journal |last1=Kitazawa |first1=Kota |last2=Oji |first2=Tatsuo |last3=Sunamura |first3=Michinari |title=Food composition of crinoids (Crinoidea: Echinodermata) in relation to stalk length and fan density: their paleoecological implications |journal=Marine Biology |date=28 June 2007 |volume=152 |issue=September 2007 |pages=959-968 |url=https://link.springer.com/article/10.1007/s00227-007-0746-5 |access-date=2 July 2024}}{{cite web |last1=Featherstone |first1=Charles M. |last2=Messing |first2=Charles G. |last3=McClintock |first3=James B. |title=Dietary Composition of Two Bathyal Stalked Crinoids: Neocrinus decorus and Endoxocrinus parrae (Echinodermata: Crinoidea: Isocrinidae) |url=https://www.semanticscholar.org/paper/Dietary-Composition-of-Two-Bathyal-Stalked-decorus-Featherstone-Messing/bf3ea4b55793ac01a4a63227dc4c51694d8df7c6#citing-papers |website=Semantic Scholar |access-date=2 July 2024}} This species has been observed to crawl across the sea floor using its arms, "elbow-crawling" at speeds of about {{Convert|36|m/h|ft/h}}. This locomotion is theorized to allow the sea lily to move to a location with more appropriate currents, or to evade slower predators such as cidaroid sea urchins.{{cite web |last1=Baumiller |first1=Tomasz |last2=Messing |first2=Charles G. |title=Stalked crinoid locomotion, and its ecological and evolutionary implications |url=https://www.researchgate.net/publication/286605145_Stalked_crinoid_locomotion_and_its_ecological_and_evolutionary_implications |website=ResearchGate |publisher=Palaeontologia Electronica |access-date=2 July 2024}}
