Seaweeds growing on rocks can be dangerously slippery. Animals and plants in the marsh are easily disturbed. Try to view from a distance, staying on a path, rather than going directly into the wetland. Touch animals gently with wet hands. Most tidepool animals have a coating of slime to protect them.
Dry hands can damage the animals.
Use other senses including listening for the sounds of the area and smelling the scents. Leave animals, rocks and shells as you found them. Changing the habitat of tidepool animals and plants or moving them to new surroundings can injure or kill them. If you look under a rock return it to how and where you found it. These organisms are alive and adapted to a very specific environment.
