Beauty can be deceptive

Some sea creatures look harmless or even particularly beautiful, but they can be poisonous. Striking colors or patterns often serve as a warning signal for potential predators.

 

Small animals with a strong effect

Among the best-known poisonous sea dwellers are certain snails, jellyfish, or fish. Their venom is usually used for defense or hunting prey and is rarely dangerous to humans if kept at a distance.

 

Observe instead of touching

When diving or snorkeling, there is a simple rule: never touch animals. Those who only observe sea creatures and keep a respectful distance protect themselves and at the same time the sensitive organisms.
