Just imagine yourself cruising on the Essequibo River through the black of night, maybe lit only by a pale moon. Your guide shines the spotlight and there it is… the red-eye glare of the Black Caiman! Frequently and closely seen lying on the river banks, the world’s largest of the alligator family grows to 6 meters (20ft.) long. A boat ride at night may also introduce you to other nocturnal creatures such as Tree Boas, Pacas, Nightjars, and Hula tree frogs..
