I had an interesting encounter with some mudskippers on the beach in Phuket, Thailand. Normally, these fish live in mangroves (brackish water). But here, the muskippers were in a fully marine lagoon. Very surprising. This is probably the most interesting fish in the world, because it's semi terrestrial !!!! I had really hard time filming them. They have very good eyesight and they run very fast))). I think these are Periophthalmus gracilis (but I am not 100%) . If you get bored, please sign up for my youtube channel
