Species Overview
Guppy
The guppy is one of the most widely distributed tropical fish, found in freshwater habitats across the Americas. Males display vivid colors and elaborate tail patterns to attract females. They are live-bearers, giving birth to free-swimming fry.
Summer Flounder
The summer flounder, or fluke, is a flatfish that lies camouflaged on the ocean floor. Born with eyes on both sides, one eye migrates to the left side during development. An ambush predator, it explodes upward to grab passing prey.
