The mullets or grey mullets are a family (Mugilidae) of ray-finned fish found worldwide in coastal temperate and tropical waters, and some species in fresh water. [1] Mullets have served as an important source of food in Mediterranean Europe since Roman times. The family includes about 78 species in 26 genera. [2]

Contents

Mullets are distinguished by the presence of two separate dorsal fins, small triangular mouths, and the absence of a lateral line organ. They feed on detritus, and most species have unusually muscular stomachs and a complex pharynx to help in digestion. [1]

Taxonomically, the family is currently treated as the sole member of the order Mugiliformes, but as Nelson says, "there has been much disagreement concerning the relationships" of this family. [3] The presence of fin spines clearly indicates membership in the superorder Acanthopterygii, and in the 1960s, they were classed as primitive perciforms, [4] while others have grouped them in Atheriniformes. [5] They are classified as an order, Mugiliformes, within the subseries Ovalentaria of the clade Percomorpha in the 5th Edition of Fishes of the World . [3]

In North America, "mullet" by itself usually refers to Mugilidae. In Europe, the word "mullet" is usually qualified, the "grey mullets" being Mugilidae and the "red mullets" or "surmullets" being Mullidae, notably members of the genus Mullus . [6] Outside Europe, the Mullidae are often called "goatfish". [7] Fish with common names including the word "mullet" may be a member of one family or the other, or even unrelated such as the freshwater Catostomus commersonii . [8]

However, recent taxonomic work has reorganised the family and the following genera make up the Mugilidae: [9] [2]

Behaviour

A common noticeable behaviour in mullet is the tendency to leap out of the water. There are two distinguishable types of leaps: a straight, clean slice out of the water to escape predators and a slower, lower jump while turning to its side that results in a larger, more distinguishable, splash. The reasons for this lower jump are disputed, but have been hypothesised to be in order to gain oxygen rich air for gas exchange in a small organ above the pharynx. [10]

Development

The ontogeny of mugilid larvae has been well studied, with the larval development of Mugil cephalus in particular being studied intensively due to its wide range of distribution and interest to aquaculture. [11] The previously understudied osteological development of Mugil cephalus was investigated in a 2021 study, with four embryonic and six larval developmental steps being described in aquaculture-reared and wild-caught specimens. [11] These descriptions provided clarification of questionable characters of adult mullets and revealed informative details with potential implications for phylogenetic hypotheses, as well as providing an overdue basis of comparison for aquaculture-reared mullets to enable recognition of malformations. [11]

It is found in Australia and New Guinea where it occurs in muddy freshwater habitats and mangroves, it feeds on algae and insects taken from the surface but also on benthic invertebrates. It can breathe air and sometimes moves over exposed mud by wriggling. It was formerly classified in the genus Rhinomugil, with the corsula, but is now placed in its own monospecific genus, Squalomugil.

It is a subtropical species which is found in deep, slow flowing sections of rivers as well as in estuaries although it moves into coastal seas to spawn. It feeds mainly on algae and plant material, as well as detritus and benthic invertebrates.
