Meet the strange Amazon fish that ‘climb’ trees during flood season in search of fruit, seeds and survival and why seeing it is one of the world's greatest wildlife experiences

During the Amazon's annual flood season, fish access submerged forests for food. Giant fruit-eating fish like the tambaqui jump to pluck fruits from branches. These fish act as important seed dispersers, aiding rainforest regeneration. Travelers can witness this unique phenomenon through guided canoe excursions. The high-water season from February to May offers the best viewing opportunities.
