Sightings are rare and always special, the kind of find that makes a snorkel trip unforgettable. Here's how to spot one near Jacó, plus five fun facts.

How to spot the pacific seahorse near Jacó

Look slowly and closely along seagrass, soft corals, and sheltered reef edges, where a seahorse anchors itself with its curled tail and sways gently with the current. Its color often matches whatever it's holding onto, so patience is everything — but spotting that unmistakable curved shape is one of snorkeling's great rewards.

5 fun facts about the pacific seahorse

• Dad carries the babies. In seahorses it's the male who gets pregnant — he carries the eggs in a belly pouch and gives birth to tiny, fully-formed young.
• A tail that grips. Its prehensile tail works like a monkey's, curling around seagrass and coral to anchor it against the current.
• A swiveling, independent eye. Each eye can move on its own, letting it watch for food in one direction and danger in another at the same time.
• It eats without teeth. It has no teeth and no stomach; it sucks tiny shrimp and plankton up through its long snout and digests them fast, so it feeds almost constantly.
• The biggest of its kind. The Pacific seahorse is one of the largest seahorses in the world, able to reach nearly a foot in length — though a sighting of any size is a rare treat.
