SHARP SPINES AND POISONOUS MUCUS are the first lines of defense for silver catfish, which at times are so thick in the channels that local people can catch them in the traditional manner with baskets. A young jacana (below) flees by diving under the lily pads with only its beak protruding for air. The bird's splaying feet, with their greatly elongated toes and claws, enable it to walk where others can't easily tread, earning it the nickname "lily-trotter."
