Keep your eyes open, according to locally collected citizen science data April is the month to see seahorses on Koh Tao. These sightings are not as common as you might think, and each observation is an invaluable piece of information in understanding the puzzle of these shy, curious creatures’ populations that are hiding out there in the waters around our island. We began our seahorse studies in 2012, and since 2013, the community of Koh Tao has been working with iSeahorse.org to track and monitor seahorse populations as observed by divers. Any divers who see a seahorse either underwater or even washed up on the beach are able to report their sightings to the site, or to iNaturalist.org. After 7 years of data collection, we are starting to see some interesting trends.
