In collaboration with Project Seahorse and iNaturalist, marine conservation groups committed to the conservation and sustainable use of the world’s coastal marine ecosystems and inhabitants, iSeahorse is a database for monitoring global seahorse populations and conservation efforts. During our seining activity, students collect real-time data including weather conditions, species identification, sex, and size of seahorses before releasing them back into the wild. Scientists and experts around the world use this vital information to better understand seahorse behavior, species ranges, and the threats seahorses face. Through this citizen science project, students and volunteers improve their understanding of seahorses and aid in protecting them from overfishing and other threats.
