Neonate garter snakes, Thamnophis sirtalis, and brown snakes distinguish conspecific from heterospecific odors (Burghardt 1977, 1983). Newborn timber rattlesnakes, Crotalus horridus, are able to follow conspecific odor trails (Brown and MacLean, 1983). Neonate water snakes are attracted to conspecific odor (Scudder et ah, 1980) and neonate prairie rattlesnakes, Crotalus viridis, to lipoids from the epidermis of adult conspecifics (Graves etal., 1987).

I think we went to Bushnell in early Fall of 1943. We joined you and others there. The objective there was to study several gases released under jungle conditions. Our job was to set out a string of bubblers, and later other apparatuses, along trails in the jungle. After the bombs went off, or were dropped from airplanes, we went in and took samples. This was somewhat scary, especially at night because one was alone with poisonous water snakes as well as the poison gas in the dark and far from anyone. Poisoned birds sometimes dropped dead from the trees.

Behind the toucan there is a Yakumama, a water snake called upon by the shaman to help heal patients. Near the shaman there is an anguila mama [electric eel] with three vegetalistas, a toad, and a salamander riding on its back. In the centre of the painting we see ayana-sirena [black mermaid], who kidnaps human beings and takes them to deep caves under the water. Several atun-huarmi [fairies] are surrounding the shaman. They come from Saturn. 

In the lake beyond there is a great water snake, called Puka-purahua. Magnetic rays shoot from hereyes, by which she is able to attract anything coming from above. This snake can transform herself into boats of various shape [see Vision 20],...

Snakes are amongst the most feared of aU creatures simply because a handful of species are lethal to humans. It is perhaps a forhmate quirk of evolution that snakes strike fear into us, because this means that we leave them alone. On the other hand some harmless snakes, for example the Common Water Snake (Nerodia sipedon) from north America, are killed because they look like dangerous species (in this case the dreaded Water Moccasin or Cottonmouth Agkistrodon piscivorus)). This is an unfortimate quirk of evolution, because the Brown Water Snake has evolved to mimic the dangerous Water Moccasin in the hope of frightening away potential predators. The outcome, however, as far as humans are concerned, is quite the opposite.
