Species Overview

オニカマス

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.

The guppy is one of the most widely distributed tropical fish, found in freshwater habitats across the Americas. Males display vivid colors and elaborate tail patterns to attract females. They are live-bearers, giving birth to free-swimming fry.
