A person who goggles or stares with wide eyes; also, any creature or object with large prominent eyes.
From 'goggle' (verb) plus the agent suffix '-er,' creating a noun for something or someone that goggles or has bulging eyes.
Fish with huge eyes are sometimes called 'gogglers'—it's a delightfully descriptive way of naming animals based on their most obvious feature, similar to how we call things 'long-necks' or 'big-heads.'
