Why are golden lanceheads so popular?
Golden lancehead snakes are in very high demand in the black market. Wealthy animal collectors from around the world are particularly interested in the species due to their uniqueness. Overzealous scientists, eager to make medical breakthroughs, also drive the high demand on the black market. The island is therefore frequented by wildlife smugglers keen to cash in on the lethal vipers. Experts estimate that a single golden lancehead snake can go for between $10,000 and $30,000, which is an attractive sum of money for the poachers. Research suggests that the illegal removal of individuals from the island could be a reason behind the decline of the golden lancehead population. Poaching is particularly harmful to the species since it targets the largest and thus the oldest individuals, which are also the most reproductively mature. Targeting such older snakes means that fewer snakes in the population reach old age classes leaving higher proportions of younger snakes. Studies also reveal that body size is usually positively related to fecundity, especially in female reptiles. A decline of older and larger individuals could, therefore, lead to a drop in average population fecundity, which negatively affects population growth. Similar trends are observed in the green python ( Morelia viridis) populations in Oceania. Targeting adult females can, however, be advantageous when establishing colonies of captive-bred snakes.
