A spiny seahorse 💛 This rare ocean fish can be found across the Indo-Pacific region. They can be easy to miss, as they are only about the length of a pen and can shift colour to bright yellow, red, grey or even green. This helps it blend in with its surroundings. #EarthCapture by @_bugdreamer_ . . . . #SpinySeahorse #OceanFish #IndoPacific | BBC Earth
