The strange and wonderful fish of Indonesia
1 | SeahorseEnglish name: Sea Horse - Subject name: Hippocampus
The seahorses belong to the group of fish, even if they hardly look like that with their small fins and upright posture.

The mother gives the food (yolk) for the offspring, the father is responsible for carrying around, breathing and protecting. After almost two weeks, many small seahorses are released from the sack into the sea.

The puffer fish have an enlargement of the stomach into which they can pump water. Instead of dandruff, there is her body covered with small spines, which now stand up and serve as barbs.
So it is hardly possible for the predator to swallow the fish. It is important that the fish are not inflated for "fun". If your dive guide wants to do this, please stop him.
For the fish, the inflation is with great stress connected and they are more vulnerable afterwards. Outside of the water, they could become inflated with air and suffocate.
