Cuisine & Edibility

Great Hammerhead Shark

Zebra Danio

Not consumed — a hardy ornamental aquarium fish notable for its horizontal blue-silver stripes and active schooling behavior; also a widely used laboratory model organism.

Species Overview

Great Hammerhead Shark

The great hammerhead is the largest of the nine hammerhead shark species. Its distinctive cephalofoil (hammer-shaped head) houses an array of electroreceptors that allow it to detect stingrays buried beneath the sand.

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.
