Firm, lean white flesh with a mild flavor when small; larger individuals risk ciguatera fish poisoning and are generally avoided. Smaller fish eaten grilled or fried in the Caribbean.

Species Overview

巴拉金梭鱼

The great barracuda is a fearsome-looking predator found in tropical and subtropical oceans. With its torpedo-shaped body, pronounced underbite, and fang-like teeth, it can strike prey at speeds exceeding 58 km/h.

Plecostomus

The common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.
