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.

Neon Tetra

The neon tetra is one of the most popular freshwater aquarium fish, known for its iridescent blue and red horizontal stripes. Native to blackwater streams of the Amazon basin, it thrives in schools of six or more.
