Marty’s photo of the day #2624: It’s “Animals A thru Z Month.” Each day in August, I will post an animal I’ve photographed—somewhere in the world—in alphabetical order.

M is for Mudskipper. Mudskippers are a fish that spends more time out of water than in it. They breathe on land by absorbing oxygen through their moist skin, they propel themselves by using their fins as legs, and since fish don’t have eyelids, they keep their eyeballs moist by periodically retracting them into their sockets. These unique adaptations give mudskippers the ability to remain on land for a day or more. (Photographed in Australia)
