Seahorses are one of the most interesting species of sea life in both appearance and how they live. Here are some facts!

Is a seahorse a fish?

Yes, seahorses are classified as fish, even though they look like a worm wearing a horse’s head. This is because they live in the sea, often mistaken for worms by unsuspecting humans. However, they don’t look like a horse when you get down and personal with their worm-like body.

Where does seahorse live?

Seahorses are primarily found in close to shallow sea waters, but they have also been seen near the water’s surface and as deep as 125 feet. They seem to prefer temperate and tropical climates, but they have been found in places like the Great Barrier Reef, Philippines, Indonesia, Bermuda, and Florida. They are also highly territorial creatures, so they stay within a particular population area. This means that unlike fish such as tuna or sharks that swim vast distances looking for prey, seahorses only hunt in a very small part of their territory.

The amount of sea space covered by each individual has been studied over the years. It has shown quite clearly that if there is an abundant source of food available, then individuals expand their territories. When resources diminish on one patch, the seahorse will retreat to another place within its territory until food resources are abundant.

The Seahorses Diet – What do they eat?

Seahorses have no teeth and a simple digestive system without a stomach. They feed primarily on small insects, crustaceans, mollusks, and even larval fish.

Seahorse Lifespan

A seahorse has a lifespan anywhere from a few weeks to 3 years if they’re not getting caught by predators. Some species of sharks and other big fish prey on seahorses and will have them for a meal. They’re always at risk of being caught by people who are often fishing lines to catch other fish. Their slow movement means quickly getting stuck to the line and caught. There are also concerns about pollution in oceans hampering their ability to breed in their habitats and the effects of global warming on sea life that could affect them.

When do seahorses mate and give birth?

The life cycle of the seahorse consists of three stages: pre-hatching (egg stage), hatching (fetus or baby), and post-hatching (juvenile). Pre-hatching starts when the female deposits her eggs on a substrate which will serve as an anchor and at the same time protect her eggs. The gestation period varies from 2 – 3 weeks depending on the species of seahorse, but in all cases, it is considered highly long compared to most other fish species. Once a male fertilizes an egg, its composition changes drastically from transparent to milky opaque, which helps conceal them from predators that can see through the water. At the same time, they are still small and vulnerable.

Adult seahorses have been reported to mate all year round and during major seasonal spawning events where large numbers of individuals come together in one place, such as in the Philippines or Indonesia. Some reports suggest that mating usually happens close to or directly on top of a coral reef where there are plenty of corals on which they can anchor themselves during reproduction. This has led many to believe that their mating rituals have been influenced by the availability of reefs where they can hide and is also why most seahorse species are found in shallower water near coastal regions rather than out at sea. Male seahorses will be pretty territorial when it comes time for breeding. If a male spots another member of his species, he will attempt to fend off the intruder by biting and “boxing” with them using their snout (nose). Sometimes this results in one of the males dead or seriously injured due to exhaustion from fighting or trying to bite each other’s tails off.

The female has a long egg tube extending from her abdomen up to several inches out from her body and is surrounded by skin that will expand slightly when she deposits her eggs inside it. The number of eggs she lays varies between 1-3, but sometimes there may be more (4 – 6). This tube is constructed with many winding parts and turns to take up as much space as possible within itself without being damaged or destroyed during depositing its contents.

Are they monogamous or polygamous?

It is unknown whether seahorses are monogamous or polygamous. The male has a pouch under his throat where the female deposits her eggs, and they will remain there until they hatch weeks later, after which time both parents take part in raising their young while being able to defend them from predators by using their large snouts as a weapon.

Can you keep a seahorse as a pet?

Well, kind of! But they’re complicated and have high requirements. Normal pet shops don’t sell seahorses because they easily die if their conditions aren’t optimal. Water quality, temperature, salinity, and food play an important role. We recommend reading this guide if you’d like to know more about seahorse pets.
