Quick answer
Seahorses feed on tiny crustaceans, adjusting with season, age, and what is abundant in Seagrass beds, reefs, and estuaries. That label is a preferred pattern, not every item an individual might sample.

Seahorse diet overview
Seahorses (Hippocampus) are best summarised as Carnivore (tiny crustaceans). Anatomy and habitat (Seagrass beds, reefs, and estuaries) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How seahorses find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Seahorse role in the food web
As predators or scavengers, seahorses move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild seahorses. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Pregnant fathers
Seahorses are famous for male pregnancy. The female deposits her eggs into a special brood pouch on the male's belly, where he fertilizes and carries them, supplying oxygen and nutrients, until he gives birth to dozens or even hundreds of tiny, fully formed young.
An unusual fish
Despite appearances, seahorses are true fish. They swim upright, propelled by a small, rapidly beating dorsal fin, and steer with tiny fins behind the eyes. With no scales, their bodies are protected by bony plates under the skin, and a prehensile tail lets them anchor to seagrass and coral against the current.

What do seahorses eat?
Seahorses feed on tiny crustaceans, adjusting with season, age, and what is abundant in Seagrass beds, reefs, and estuaries. That label is a preferred pattern, not every item an individual might sample.
What is the scientific name of the seahorse?
Hippocampus — used in research and conservation listings for seahorses.
Where do seahorses live?
They are associated with Seagrass beds, reefs, and estuaries. Local presence depends on food, cover, and human land use.
What is the conservation status of seahorses?
Listed in our guides as Vulnerable. Check the IUCN Red List and national assessments for the latest formal category.
