The World’s Smallest Seahorse

Satomi’s pygmy seahorse, endemic to Indonesia, is one of the world’s tiniest seahorses. Two adults would fit head-to-head across the face of a penny and their offspring are each about the size of a 12-point apostrophe.

At under half an inch tall (13 millimeters), Satomi’s pygmy seahorse — named after dive guide Satomi Onishi — is a strong contender for the world’s smallest seahorse. With their tails stretched out straight, two Satomi’s pygmy seahorses would fit head-to-head across the face of a penny.

These miniscule seahorses from Indonesian reefs have been seen giving birth to tiny offspring, each about the size of a 12-point apostrophe.

Together with two other species, Satomi’s pygmy seahorses were named in a December 2008 study.

    Ha! I love how the size of the baby seahorse was described by font size. That gave me a very clear picture!
