Tropical Rainforest Ecology Rainforest Animal Life
Rainforest Mammals: Monkeys • Capuchin – most commonly seen monkey; medium size brown to black body; pale face surrounded by whitish fur; move in troops; eat fruits, leaves, arthropods, & sometimes small mammals
Rainforest Mammals: Monkeys • Spider – large size but very slender brown to black body; pale face surrounded by whitish fur; long prehensile tail; move in troops; eat fruits & leaves; brachiation
Rainforest Mammals: Monkeys • Mantled howler – large robust size; black body w/tan on sides and back; bearded face; prehensile tail; loud voice @ dusk & dawn; primarily eat leaves; prefers canopy
Rainforest Mammals: Monkeys • Geoffrey’s tamarin – small and squirrel-like; long tail not prehensile; like forest gaps; eat insects & fruits; red nape & highly patterned body; often have twins
Rainforest Mammals:Monkeys • C.A. Squirrel – endangered species; smaller size w/extremely long black-tipped tail; white mask and ears; very active fruit eater • Night monkeys – entirely nocturnal; tail not prehensile
Rainforest Mammals: Rodents • Agouti – diurnal; large & guinea pig-like; tailless; sit upright to eat seeds
Rainforest Mammals: Rodents • Paca – nocturnal; near water; like large agouti w/white stripes
Rainforest Mammals:Rodents • Capybara – diurnal; largest rodent in the world; aquatic; feeds on aquatic vegetation • Spiny rat – nocturnal; spines in fur; on forest floor • variegated squirrel – arboreal

Rainforest Reptiles:Pitvipers • All are poisonous • Tend to be secretive and nocturnal • Not frequently encountered • Pits for detecting warm-blooded prey • Retractable fangs to deliver venom • Slit pupils • Many non-poisonous snakes in the neotropics will mimic pitvipers, so always err on the side of caution
