Hippocampus Hippocampus

Short-Snouted Seahorse

Shallow coastal waters, often among seagrass beds, coral reefs, and mangroves

The Short-Snouted Seahorse, hippocampus hippocampus, is a fascinating marine fish known for its distinctive horse-like head and curled tail. This species typically reaches a length of 12 to 15 cm and is characterized by its small, upturned snout, which is shorter than that of other seahorse species. The body is slender and encased in bony plates, providing protection from predators. Coloration varies widely among individuals, ranging from green and brown to yellowish, often with various markings that help camouflage them among seagrass and other underwater vegetation.

Short-Snouted Seahorse
Population:Listed as Data Deficient by the IUCN, but believed to be under threat from habitat loss and exploitation
Generation Length:1-2 years
Average Weight:Not well documented; seahorses are generally light due to their small size
Average Length:10-15 cm
Lifespan:1-5 years in the wild
Diet:Micro-carnivorous, feeding on small organisms in the water column
Conservation Status:Near Threatened (NT)
Echological Profile

Native to the coastal waters of the Mediterranean Sea, parts of the North Atlantic, including the British Isles and the Canary Islands, the Short-Snouted Seahorse inhabits shallow, temperate waters. It prefers areas with abundant vegetation, such as seagrass beds, where it uses its prehensile tail to anchor itself against currents and hide from predators. Despite their swimming ability, Short-Snouted Seahorses often remain stationary, relying on their camouflage to blend into their surroundings.

The diet of the Short-Snouted Seahorse consists primarily of small crustaceans and plankton. Its unique method of feeding involves sucking prey into its mouth through its elongated snout, acting like a vacuum. This efficient feeding mechanism allows it to consume food particles suspended in the water or picked from the substrate.

Reproduction is a notable aspect of seahorse biology, with males carrying the fertilized eggs in a specialized brood pouch until they hatch. The female deposits her eggs into the male's pouch, where he fertilizes them internally. After a gestation period of about 2 to 4 weeks, the male gives birth to fully formed, miniature seahorses, ranging in number from a few dozen to over a thousand, depending on the species.

The population of the Short-Snouted Seahorse is declining due to habitat destruction, pollution, and bycatch in fishing nets. It is also collected for the aquarium trade and traditional medicine, further impacting its numbers. Conservation efforts are focused on habitat protection, sustainable fishing practices, and legislation to regulate trade. The Short-Snouted Seahorse's unique reproductive strategy and ecological role underline the importance of conserving marine biodiversity.

Fun Fact

The short-snouted seahorse can change its color to blend with its surroundings, aiding in camouflage.

This ability helps them avoid predators and communicate with other seahorses. Found in shallow waters, these seahorses use their prehensile tails to anchor themselves to seagrasses and corals. They are monogamous and engage in unique courtship dances, strengthening their bonds.
