Apri l'appDescrizione
Mugil cephalus, commonly known as the Flathead Grey Mullet, is a cosmopolitan species of mullet found in coastal tropical and subtropical waters worldwide. It is an euryhaline and catadromous fish, meaning it can tolerate a wide range of salinities and migrates from freshwater to saltwater to spawn. This species is characterized by its robust, cylindrical body, small mouth, and distinctive adipose eyelid. It is an important food fish globally and plays a significant ecological role as a detritivore.

Consigli per l'identificazione
Adipose Eyelid
The most distinguishing feature is the thick, fatty eyelid that covers a significant portion of the eye, leaving only a vertical slit for the pupil. This is absent or much less developed in many other mullet species.
Dorsal Fins
Two distinctly separate dorsal fins. The first dorsal fin has four strong spines, while the second has soft rays. This separation is a key identifier.
Mouth Shape
A small, terminal mouth with relatively thick lips. The mouth is not inferior or superior, but directly at the front of the head.
Coloration and Stripes
Olive-green to bluish-grey back, silvery sides, and white belly, often with 6-7 faint dark longitudinal stripes along the sides. These stripes can be more pronounced in some individuals.
Habitat
- Tipo di acqua
- brackish
- Profondità
- Typically found in shallow coastal waters, estuaries, lagoons, and even freshwater rivers, usually from the surface down to about 120 meters (390 feet).
- Ambiente
- Coastal marine waters, estuaries, lagoons, rivers, and sometimes freshwater lakes. Prefers muddy or sandy bottoms where it can forage for detritus and algae. Highly euryhaline, tolerating a wide range of salinities from hypersaline to freshwater.
- Areale geografico
- Circumglobal in tropical and subtropical waters. Found in the Atlantic, Indian, and Pacific Oceans, including the Mediterranean Sea, Black Sea, Gulf of Mexico, and Indo-Pacific region.
Informazioni sull'acquario
- Livello di cura: advanced
- Temperamento: peaceful
- Dieta: filter_feeder
- Dimensione minima della vasca: 500 gallons
- Temperatura: 18-28°C (64-82°F)
- Livello di pH: 7.0-8.5
- Durezza: 10-25 dGH
- Compatibilità: Generally compatible with other large, peaceful, euryhaline species. Avoid aggressive or highly territorial tankmates.
- Requisiti speciali: Requires a very large tank with excellent filtration due to its size and detritivorous feeding habits. Needs a substrate that allows for foraging. Can be kept in brackish or marine setups, and can adapt to freshwater over time, but spawning requires saltwater. Not typically a home aquarium species due to size and specific needs.
Informazioni in natura
- Stato di conservazione: least concern
- Stagionalità: Spawning typically occurs in offshore marine waters during cooler months (autumn/winter in temperate regions, year-round in tropical areas). Availability for fishing can vary seasonally based on migration patterns.
- Prezzo di mercato: Varies significantly by region and market demand, often moderate to high due to its culinary versatility and roe.
- Importanza commerciale: high
- Sapore: Mild, somewhat earthy, can be oily depending on diet and season.
- Consistenza: Firm, flaky, white flesh.
- Metodi di cottura: Grilled, Baked, Fried, Smoked, Steamed, Used for roe (bottarga)
- Valore nutrizionale: Good source of protein, Omega-3 fatty acids, and various vitamins and minerals. Roe (bottarga) is highly prized and rich in nutrients.
Fatti chiave
Global Traveleramazing
Mugil cephalus is one of the most widely distributed fish species in the world, found in tropical and subtropical waters across all major oceans.
Euryhaline Masterbehavior
This species is highly euryhaline, capable of thriving in a vast range of salinities, from pure freshwater to hypersaline conditions, making it incredibly adaptable.
Detritivore's Roleinteresting
As a detritivore, the Flathead Grey Mullet plays a crucial ecological role in coastal ecosystems by consuming detritus, algae, and small invertebrates, helping to recycle nutrients.
Prized Roeinteresting
The roe of Mugil cephalus is a highly valued delicacy in many cultures, particularly in the Mediterranean (bottarga) and Asia, where it is cured and consumed.
Leaping Fishbehavior
Mullets are known for their tendency to leap out of the water, a behavior thought to be related to avoiding predators, dislodging parasites, or obtaining oxygen from the air in low-oxygen environments.

Thinlip Mullet
Liza ramada
Liza ramada has much thinner lips and lacks the prominent adipose eyelid of Mugil cephalus. Its pectoral fin typically reaches the eye when folded forward, which is not the case for M. cephalus.
Thicklip Mullet
Chelon labrosus
Chelon labrosus has noticeably thicker, fleshy lips, especially the upper lip, and also lacks the well-developed adipose eyelid seen in Mugil cephalus. It often has a dark spot at the base of the pectoral fin.
Golden Grey Mullet
Liza aurata
Liza aurata is distinguished by a prominent golden spot on each operculum (gill cover) and lacks the strong adipose eyelid of Mugil cephalus. Its body is generally more slender.
