The small mammal team traps a handsome brown four-eyed opossum (Metachirus nudicaudatus), which everyone falls in love with before his release into the forest night. Another strikingly good-looking species to be registered is the Aesculapian false coral snake (Erythrolamprus aesculapii) and the ichthyologists have a stellar day with at least ten fish species added to the site list including two larger species and Bolivian classics, the wolf fish (Hoplias malabaricus) and the sabalo (Prochilodus nigricans).
