Species Overview
Cobia
The cobia is a powerful pelagic fish that often follows large rays, sharks, and turtles. Its flattened head and elongated body resemble a shark. Excellent table fare with firm, white flesh, it is increasingly farmed in aquaculture.
Zebra Danio
The zebrafish is a small cyprinid native to South Asia's freshwater streams. Its distinctive blue-and-gold horizontal stripes and hardy nature make it a popular aquarium fish. It is also the most widely used vertebrate model organism in genetic research.
