Conservation & Threats


There are no known threats to C. glebosus and it has not been assessed for the IUCN Red List.


Possible threats to crinoids are the possibility of ocean acidification and increase in sediment loading in the water column.

Many studies have looked at the effects of a decrease in ocean pH levels on echinoderms due to their highly calcified body plans (Dupont 2010). There are a number of papers concluding different outcomes for echinoderms in ocean acidification with some providing results of the robustness of echinoderms against ocean acidification while other conclude that ocean acidification will have negative impacts on echinoderm phyla with large consequences at the ecosystem level (Dupont 2010).The need for longer term realistic experiments on more species of echinoderm are needed to ensure the validity of these claims.  

The increase in human activities within shallow water environments and those environments that connect to them could cause an increase in the sediment loading within the water column such as dredging and sediment run off in upstream water catchments. The effects of increasing sediments within the water column will greatly impact the efficiency and capabilities of crinoids to filter feed (Alender et al 1966). Further information of C. glebosus is needed to create a great biogeographical distribution to view for impacts of human induced sediment increases in the water column of shallow water habitats.
