Confocal micrographs of the serotonergic nervous system in pelagosphera larvae of Themistepyroides. All aspects in ventral view except I, K, J and L, which are in ventro lateral left view. Anteriorfaces upwards and scale bars represent 50 µm in A, E, I, K, J and L, while they equal 10µm in B, C, D,F, G and H. A, E, I, and K are color-coded confocal micrographs, where blue and purple colors are
