What Are Some Adaptations For A Seahorse?

- They are able to change colours and camouflage from predators, and attack their prey.
- Their long tails enable them to wrap around and hold on to seaweeds.
- They have long snouts to suck up food.
- They have mobile eyes to look out for predators and preys without movings its body.
-They have pectoral fins located at the side of the head, enabling them to swim in any direction.

They can blend in with their surroundings

There eyes help detect predators coming from the side

Marine adaptations are more or less the same for all the organisms...
They have a kind of air-bladder to help them float ....( I can't remember the term used for it)
they have improved osmotic regulations
they have thick mucilage cover to avoid the rotting effect of the water
their body is laterally flat to provide least resistance to the flow of water....
And many more....

They have no skin. Their skeleton is on the outside.

My best guess would be that they would use camouflage, and use their tail to attach to coral and seaweed, or, maybe as previously suggested, they would run away.
