Are starfish safe to touch?

Published in Marine Biology 1 min read

No, starfish are generally not safe to touch without considering their well-being.

While starfish may appear hardy, touching them can be harmful due to their delicate respiratory system. Here's why:

  • Respiratory Issues: Starfish respire by absorbing oxygen from the water using a mucous substance on their surface. When touched, this substance can be removed, hindering their ability to breathe effectively.
  • Suffocation Risk: Prolonged handling can lead to suffocation as the starfish struggles to absorb enough oxygen.
  • Embolisms: Removing a starfish from the water exposes them to air, which can cause embolisms, even if the starfish initially seems to survive.
  • Stress: Any handling can stress a starfish, weakening its immune system and making it more susceptible to disease.

Therefore, it is best practice not to touch starfish in their natural environment. If absolutely necessary (e.g., for scientific research), minimize contact, keep them submerged in water, and return them to their original location immediately. Always prioritize the animal's well-being.
