A translucent cylinder forming part of the light-sensitive receptor in the eye of an arthropod.
- ‘Thus, in some parts of the retina the larval rhabdoms are incorporated into the receptor array.’
- ‘As mentioned above, the screening pigment is essential; otherwise, the rhabdoms would receive light from all directions, destroying any spatial information.’
- ‘In most species that have only a single visual pigment in main rhabdoms as adults, the larval pigment appears to be identical to that of the adult.’
- ‘The receptors have long fused rhabdoms and are surrounded by a tracheal tapetum.’
- ‘Postlarvae settling at the vents have reasonably normal ommatidia, with layered rhabdoms, standard crystalline cones, and faceted external corneas reflective of the zoeal apposition eye.’
Late 19th century: from late Greek rhabdōma, from rhabdos ‘rod’.
