In the oceans of the world, where are more seahorses? Mediterranean? Indian Ocean? Tell me more about those countries.

Hippocampus is not strict with the water quality of living environment. In natural waters, seahorses usually like to live in slow-moving coral reefs, while corals, that is, organisms that form coral reefs, mainly live in warm and vast shallow sea environments, with the most in the central Pacific Ocean and relatively few in the Indian Ocean and Atlantic Ocean. Therefore, we can judge that more seahorses should live in shallow coral reefs near China, Australia, Indonesia and some island countries in the South Pacific, such as the Great Barrier Reef and Malay Archipelago in the northeast of Australia.
