How Do Fish Maintain Neutral Buoyancy?

Why don't fish float to the top of water or sink to the bottom when they swim? It's all about density.

Pretty as a picture! This natural photo frame is made up of Tamala Limestone, found along more than 1000km of WA coast, from Shark Bay to nearly Albany. More accurately called 'aeolian calcarenite', this type of rock is made up of broken shell fragments brought ashore by waves and wind, and cemented by calcium carbonate. . 📸: @nature_camping_kids_ . . . #perthlife #explorewa #thisiwa #westernaustralia #perthbeaches #hamersleypools #indianocean #natureswindow #geology #limestone #geologyrocks

The human brain is pretty incredible. It's made up of approximately 80 billion nerve cells, called neurons that need to talk to each to keep your body functioning and your mind ticking. Here you can see the connections between brain cells! 📸: Jason Kirk / Quynh Nguyen / @nikoninstruments . . . #microscopy #microscopic #underthemicroscope #mindblowing #neurons
