Lesseptic immigrant from the Red Sea (invasive species in the Mediterranean)
A very slender fish that often stands vertically in the water to camouflage itself. It uses this posture to hide among seagrass or other structures. As a hunter, it approaches its prey inconspicuously and then strikes quickly. In the Mediterranean, it is considered an invasive species.
Where to Find in Cyprus: Dive Sites & Habitat
The trumpetfish is one of the most successful immigrants in the eastern Mediterranean and is now widespread around Cyprus. It is regularly observed at rocky reefs, seagrass meadows, artificial reefs, shipwrecks, and sheltered bays. Most sightings occur at depths between 2 and 30 meters. Divers and snorkelers, in particular, frequently encounter it, as it often hunts in shallow coastal areas. In Cyprus, the species is now considered established and can be observed year-round at many dive sites. Due to its size and unusual body shape, it is easily recognizable even by inexperienced divers.
Behavior & Key Features Underwater
The trumpetfish is a skilled ambush predator. It often swims slowly and inconspicuously alongside larger fish or hovers almost vertically in the water among seagrass and other structures. This camouflage strategy allows it to approach its prey undetected. With its long, tubular mouth, it creates a powerful suction and sucks in small fish with lightning speed. To divers, its behavior often appears curious, although it is usually focused on foraging. As an invasive species, it has spread extensively in the eastern Mediterranean and impacts local fish communities through its role as an efficient predator.
