Its very very rare to find such acuracy in herp literature. Your coments about parental care are simply excelent and very few people know about it, even in the academy. As Dr. Harry Green puts:<br /><br />PARENTAL BEHAVlOR IN VIPERS<br />(HARRY GREENE E COLS.) <br /> <br /><br />"Field studies, laboratory experiments and phylogenic analyses show that parental behavior by vipers is more interesting than previously realized. Telemetered Crotalus remain with eggs during incubation, those of 19 species in four genera remain with their young for several days after birth. And thus pits, defensive caudal sound production, and attendance of neonatcs arc hisrorically correlated. Alternatively, parental behavior appeared earlier in the evolution of snakes or even anguimorphs and later was elaborated or lost in many lineages. Pitvipers probably protect their eggs and/or offspring from predators, and aggregation might enhance thermoregulation and retard water loss by neonates. Tongue-flicking among littennates and liiothers might facilitate chemically-medialed social mechanisms. Physiological control mechanisms. Ecological consequences, variable timing of neonatal ecdysis and individual, population, and taxononomic variation in parental behavior by snakes warrant further studies"<br /><br />THANKS SO MUCH AGAIN JAVIER.<br /><br />RodrigoRodrigohttps://www.blogger.com/profile/09050259303565770207noreply@blogger.com
