The fine bristles of the feather duster allow it to capture floating plankton. It then brings them to its mouth by closing in the bristle similar to a closed umbrella.

Baby sea turtle photograph - Leatherback (Dermochelys coriacea)
This Leatherback baby sea turtle photograph was taken in open ocean. The Leatherback sea turtle gets its name because its carapace is covered by a thick leathery skin instead of the bony scutes found in all other marine sea turtles.

  Seahorses swimming upright
 
Seahorses swimming upright
Why do seahorses swim upright? They lack a caudal (tail) fin to propel them forward and so use their dorsal (back) fin to move slowly and upright. According to researchers the seahorse evolved this way due to a great expansion of sea grass beds approximately 25 million years ago. The idea is that it is easier to hide among the blades of grass by swimming vertically alongside them. Learn more.

  Seahorse identification
 
Seahorse identification
The coronet (top of the head) on some seahorses is believed to be as unique to each individual seahorse as the fingerprint on a human. I use this unique trait to help with the identification of individual seahorses where I dive regularly.

  Seahorse feeding habits
 
Seahorse feeding habits
Seahorses have no teeth or stomach. Their food literally passes right through their digestive system. Because of this seahorse spend a large part of their time feeding on tiny crustaceans or any plankton that is drifting by.

  Body color change in seahorses
 
Body color change in seahorses
Seahorses have the ability to change colors by the contraction and expansion of cells in their body called chromatophores. This color change in seahorses happen for a number of reasons which include environmental (blending in with their environment and water quality) and behavioral (courtship and territorial display) factors.

  Seahorse vision
 
Seahorse vision
The eyes on a seahorse can move independently of each other. It is believed their eyes can also work together to allow for binocular vision. The seahorse can use this binocular vision to focus in on the small crustacean and plankton creatures on which they feed.

The seahorse and Greek mythology
The seahorse was perhaps the inspiration in Greek mythology for their depiction of Poseidon and his horse-drawn ocean chariot. The seahorse's scientific name, Hippocampus, is Greek for "crooked horse." Learn more.
