Hi Fellow Reefers,
I found what appear to be two Sponge Synaptid Sea Cucumbers in a recent shipment of Dragon Bush Macroalgae and wanted to get a second opinion. They both have green-brown translucent bodies with white splotches, the longer one is about 2”(4.5mm) long and about 1/8”(3mm) wide. They both seem to be ‘sticky’ and cling to things with their ends.
Can anyone confirm ID and if they’re friend or foe? (We have multiple types of cucumbers already and would like to add them, but these seem potentially invasive)
