Another day, another snake and another new record for Madidi - a Bolivian coral snake (Micrurus obscurus)! The reptiles of the park deserve further efforts to increase knowledge about a diverse group that is difficult to observe and has few studies to date. The ichthyologists return from a day on the Machariapo with an incredible fish - the tube-snouted electric knife fish (Sternarchorhynchus sp.)!!! They hunt by poking their highly specialized snout into soft mud and between rocks and aquatic vegetation searching for benthic invertebrates that they detect and capture with electrogenic abilities.
