The Royal Belgian Institute of Natural Sciences (RBINS), is currently closed­ due to the coronavirus crisis. Visitors can until further notice unfortunately not be welcomed at the RBINS as the majority of its staff is working from home.  Consequently, RBINS can at present also not process loan requests, receive loan returns, until at least mid-May, possibly even longer… More so, data requests that require access to the collections cannot be fulfilled until staff are back at the RBINS.  We do have remote access to our databases and can provide some assistance with data requests. Thank you for bearing with us during this difficult time. Keep it Safe!

Subject: Re: Identification of Synaptid


Dear Colleagues,


Good day to all. Hope everyone is coping well during this period. My colleagues were working with some volunteers and some of the sea cucumbers were photographed during their dives in Singapore waters. We only manage to ID them to Synaptuna sp.. Can we get some advice on the species of these three sea cucumbers?


Thank you very much.
