Species Overview
Brook Trout
The brook trout is actually a char, native to cold, clean streams of eastern North America. Its olive-green body with distinctive worm-like markings (vermiculations) and red spots with blue halos make it one of the most beautiful freshwater fish.
Whale Shark
The whale shark is the largest living fish species, reaching lengths of up to 18 meters. Despite its enormous size, it is a gentle filter feeder that consumes plankton, fish eggs, and small fish by swimming with its wide mouth open.
