Small Flatworm (?) on ascidian in Lembeh Strait
Previously we discovoered a smooth green phycocaris species that we believe is undescribed and lives in tiny green ascidians. We have already seen it several times (at various divesites) since then. And that was also what we were trying to find yesterday, when we suddenly saw this little green thing on one of the ascidians. It seems to be a tiny kind of flatworm that perfectly matches the ascidian in colour, pattern and shape. And even though it has no eyes and does not move much it is still a beautiful critter. And it proves that if you look for things smaller than an olive grain you keep finding new stuff every day – at least here in Lembeh.
