White Mullet

Overview

The white mullet (Mugil curema) is a schooling, tropical and subtropical marine fish widely distributed across the Atlantic and Pacific coasts of the Americas and the eastern Atlantic. These fish are commonly found in coastal environments, where they play an important role in local ecosystems and fisheries.

Distribution & habitat

This species inhabits a variety of coastal settings, including sandy shores, littoral pools, brackish lagoons, and estuaries with muddy substrates. They are also known to occasionally enter rivers. While they prefer open waters near the surface, they are frequently found in areas with underwater flora, such as coral reefs, and juveniles often utilize estuaries and lagoons as nursery grounds.

Appearance

The white mullet has a stout, spindle-shaped body that is rounded in cross-section and tapers toward the tail. Its dorsal surface typically ranges from blue-green to olive, transitioning to a silvery-white belly. Key identifying features include a broad head with a flat inter-orbital space, a well-developed adipose eyelid covering most of the pupil, and a distinct dark spot at the base of the pectoral fins. Juveniles often display a characteristic gold or yellow patch on the gill plates.

Biology & behavior

Adults are typically found in schools and are known to be active, surface-oriented swimmers. They possess an unusually long alimentary canal, which is an adaptation for their diet. Their reproductive cycles are often linked to seasonal environmental changes, with spawning activity showing peaks that correlate with local precipitation patterns.

Feeding

White mullets are primarily detritus feeders, often grazing on mud from the bottom. Their diet also includes various forms of algae.
