Seahorse
Seahorses are small marine fish in the genus Hippocampus, known for their horse-like heads, upright swimming posture, and curled prehensile tails.
Seahorses are small marine fish in the genus Hippocampus, named for their horse-like heads and upright swimming posture. They live in shallow coastal habitats worldwide, with males uniquely carrying and giving birth to the young.
What it is
Seahorses are ray-finned fish in the family Syngnathidae, which also includes pipefishes and seadragons. Unlike most fish, they lack scales and are covered in bony plates. They use a curled prehensile tail to grip seagrass or coral, and their tubular snouts help them suck up tiny prey.
Key details
There are roughly 40 to 50 known seahorse species, found in temperate and tropical waters. They are carnivores that eat small crustaceans and other invertebrates. Male seahorses are among the only animals in nature to become pregnant and give birth. Lifespan in the wild is typically 1 to 5 years.
Why it matters
Seahorses face pressures from habitat loss, bycatch, and trade, with several species listed as threatened or data deficient. In Canada, they appear in public aquariums and marine education programs, highlighting broader conservation concerns for coastal species and habitats.
In short
- Seahorses are fish, not mammals or horses.
- Males carry and give birth to the young.
- They live in shallow coastal waters like seagrass beds and coral reefs.
- Several species are threatened by habitat loss and trade.
Seahorses are relevant to Canadian marine biodiversity through public aquariums, marine education, and conservation discussions about coastal species and habitat protection, although most species live in warmer temperate and tropical waters rather than Canadian waters.
