This article reports for the first time on an azooxanthellate brachycnemic zoantharian, Sphenopus marsupialis (Gmelin, 1791) from lower mesophotic depths (114 m depth). We have mentioned that Sphenopus species have so far only been reported only from shallow waters (< 35 m) in the paper. However, Dr. Mark J. Grygier has pointed out to the authors that S. marsupialis has previously been reported from upper to mid-mesophotic depths; 50–60 m in Indian waters (Nagabhushanam and Jothinayagam 1982) and from 40 to 86 m in Australian waters (Grygier 1991). These previous studies add even further support to our main conclusion that Sphenopus species may be much more widely and commonly distributed across the Indo-Pacific Ocean including at deeper depths. The authors regret that they overlooked the existence of these two previous reports.
