• Eyes: Large, providing excellent vision.

Distinctive Features

The Horse Eye Jack possesses several unique traits that distinguish it from other jack species:

1. Robust Eyes: The large eyes enhance its capability to hunt in varying light conditions.
2. Hydrodynamic Form: This shape allows it to maneuver swiftly through the water, evading predators and catching prey.
3. Color-Changing Ability: It can subtly change hues to communicate or blend into its surroundings.

Habitat and Distribution

Where Do Horse Eye Jacks Live?

Horse Eye Jacks are native to the Atlantic Ocean, with a range that extends from the southeastern United States, through the Caribbean, and along the coast of South America. They are perennial residents of warm coastal waters and prefer the depths of reefs, lagoons, and offshore wrecks.

Typical Habitats:

• Reefs: Rich in nutrients and biodiversity, providing ample hunting grounds.
• Open Waters: Known to form large schools in pelagic zones.
• Estuaries: Occasionally found in brackish environments during certain life stages.

Distribution Overview

Region	Commonality	Water Temperature
Southeast USA	Frequently found	24°C - 29°C
Caribbean	Very common	25°C - 30°C
South America	Common	24°C - 28°C

Environmental Preferences:

• Temperature: Prefers warmer waters, generally from 24°C to 30°C.
• Depth: Commonly found at depths ranging from 5 to 20 meters but can reach deeper waters when necessary.

Behavioral Insights

Social Structure and Schooling Behavior

The Horse Eye Jack is notably social, often found in large schools, whether hunting or migrating. This schooling behavior offers several advantages:
