"Lelts are often attracted to the salt rafts, largely by the vibrations in the water, picked up by their abnormally developed lateral-line protrusions, and their fernlike craneal vibration receptors, from the cones and poles. Too, though they are blind, I think either the light, or the heat, perhaps, from our lamps, draws them. The tiny eyeless heads will thrust from the water, and the fernlike filaments at the side of the head will open and lift, orienting themselves to one or the other of the lamps."
Book 10, Tribesmen of Gor, page 247 ~才
"The lelt is commonly five to seven inches in length. It is white and long-finned. It swims slowly and smoothly, its fins moving the water very little, which apparently contributes to its own concealment in a blind environment and makes it easier to detect the vibrations of its prey, any of several varieties of tiny segmented creatures, predominantly isopods. ." Book 10, Tribesmen of Gor, page 247 ~才
"The brain of the lelt is interesting, containing an unusually developed odor-perception center and two vibration-reception centers. Its organ of balance, or hidden 'ear,' is also unusually large, and is connected with an unusually large balance center in its brain. Its visual center, on the other hand, is stunted and undeveloped, a remnant, a vague genetic memory of an organ long discared in its evolution." Book 10, Tribesmen of Gor, page 247 ~才
"The gills of the lelt are located at the lower sides of its jaw, not on the sides of its head, as is common in open-water fish." Book 10, Tribesmen of Gor, page 248 ~才
