Dicranophorus edestes: two specimens with conspicuous birefringent crystals which are scattered in the pseudocoel. The lower 2 images demonstrate the movement of the crystrals within the body of a specimen from (5). Neither the chemical composition nor the function of these crystals is clear.
I remembered that I had seen such crystals in a another rotifer some time ago. It turns out that the crystals were found in the same dicranophorid species 3 years ago in France (upper image; specimen from (3)). |
