worms with eyes, where are they?

[Carlos Eduardo Winter]

Hi,
There are worms with eyes. The information about them is in the book 
"Physiology of Nematodes" (Lee & Atkinson; 2nd edition; Macmillan, 1976). 
An illustration in the above book shows a worm with pigment 
and lens (?) [the ref. is J. Wash. Acad. Sci. 23 (1933)]. But there is no 
nerve endings connected to the "ocelli". You should try also Croll et al. 
(1975) - Comp. Biochem. Physiol., 51A:139-143, 1975 or Adv. Parasitol., 
14:195-265 (1976). 
Lee & Atkinson remark that "almost all nematodes that possess so-called 
ocelli are marine species". So I wish you a good hunting (or fishing if 
you prefer).

Carlos
