MICROSCOPIC HAIRS IN INNER EAR:  Inner ear help divers (like the one in today's pic) know their up down orientation in water.  Sounds under water are magnified. When we hear sounds (whether under water or above) microscopic hairs in our inner ears vibrate.

Microworlds photography by Daniel Stoupin. Rhodactis sp. corallimorph that was roughly 5 cm in diameter. Multiple branching pseudo-tentacles are closely arranged because the polyp is in a somewhat contracted state. Eventually it would expand further and the distance between those fancy branching structures would increase. http://www.microworldsphotography.com/Galleries/Macro-of-corals/i-ZZzHDf3

The hippocampus is the key memory-forming center of the brain and displays high rates of neurogenesis even in adults.

Neurogenesis occurs inside the "V," where neurons are born and then migrate outward toward the dentate gryus.

Unexpected pattern by Daniel Stoupin / 500px

Favites sp under high magnification reveals interesting patterns that form stripes. Aquarists and divers will only recognize this coral if they take many steps back from the screen as the whole area is of fingernail size.
