Pygmy Seahorse

Hippocampus bargibanti

Also known as Bargibant's Seahorse, Gorgonian Pygmy Seahorse

These tiny marine masters of camouflage spend their entire adult lives anchored to a single gorgonian coral host. Measuring less than two centimeters in length, their bodies are covered in bulbous tubercles that perfectly mimic the polyps of their host coral. They are so well hidden that they were only discovered when a researcher was studying a coral sample in a laboratory.

What to notice
Look for tiny, knobby shapes matching the pink or yellow polyps of Muricella gorgonian corals.
Support conservation
Never touch the host coral or the seahorse, and limit the number of camera flashes to avoid blinding them.
Responsible observation
  • Maintain distance: Avoid touching or crowding the host gorgonian coral to prevent stressing the seahorse.
  • Limit flash photography: Bright strobe lights can damage their highly sensitive eyes and cause them to turn away.
  • Watch the polyps: Look for closed coral polyps, which often indicate a seahorse is clinging nearby.
