Presentation
The speckled seahorse is a small marine fish with a distinctive equine-like head and a prehensile coiled tail. Its body is covered with small spots or speckles that give it its common name. It is a fascinating creature that embodies the extraordinary diversity of Mediterranean and Atlantic marine life.
The speckled seahorse's body is covered with bony protuberances and small spines, giving it a rough appearance. Its coloration ranges from beige to grey-brown, always adorned with its characteristic spots. It has reduced dorsal and pectoral fins, making it a slow and unmanoeuvrable swimmer.
Characteristics
Indicative values: they vary by subspecies, sex and region.
Habitat and distribution
The speckled seahorse inhabits shallow coastal zones, seagrass beds, and Posidonia meadows in calm waters. It prefers sheltered environments where it can attach to aquatic vegetation. It is typically found between the surface level and about 30 meters in depth.
CURRENT RANGE
The speckled seahorse is found in the North-Eastern Atlantic, particularly along British and French coasts, and throughout the Mediterranean basin. Its range extends from southern Scandinavia to Morocco and the eastern Mediterranean coastal waters. Absent from Tunisia.
Behaviour
The speckled seahorse is a solitary or pair-dwelling animal that spends most of its time anchored to seagrass or algae using its prehensile tail. It moves slowly and deliberately, never covering great distances. It is a discreet and peaceful animal, reluctant to flee from predators.
Reproduction
The speckled seahorse has a unique reproductive system: the male carries eggs in his ventral pouch, equivalent to a uterus. The female deposits her eggs into this pouch where they are fertilized and incubated. Young are born fully-formed after a few weeks and are immediately independent.
Peculiarities
The speckled seahorse is the only fish in which the male ensures gestation. Its prehensile tail allows it to stabilize itself in currents and maintain its position effortlessly. It can slowly change color to camouflage itself in its environment.
Threats and conservation
The speckled seahorse is threatened by the destruction of its coastal habitat, particularly the loss of seagrass beds and Posidonia meadows. Coastal trawling, net fishing, and pollution degrade its living areas. Accidental capture and trade for aquarium use also contribute to its decline.
Numbers and trends vary across sources and regions. See the IUCN assessment for the latest reference data.
