Species Overview
Swordfish
The swordfish is a highly migratory pelagic predator recognized by its long, flat, pointed bill. It can dive to depths exceeding 2,800 meters and possesses a specialized organ that heats its eyes and brain for improved vision in cold, deep water.
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.
