“I found these worms in my isopod terrarium”, writes Cynthia about the translucent worm-like creature pictured below. “I have been searching but am unable to find out what worm it is. Would be grateful for some help! The worms are less than 5mm long and this is the clearest photo I could get. The white part is the head and all of them are coloured this way. They are too small for my eyes to see if they are segmented or not. They seem to gravitate towards damp areas in the terrarium. I live in Singapore, which is a warm and humid place. Any ideas?” To begin with, we want to point out how cool it is that Cynthia has an isopod terrarium: it’s not everyday you hear that, and we appreciate her appreciation of such critters.
