In return, the clownfish keeps the anemone clean and provides nutrients through its waste—a perfect example of mutualism!
What anemones are safe to touch?
Anemones use the stinging cells that cover their tentacles to catch food and protect themselves from predators. The species of anemone at Haystack Rock are safe to touch! Their stinging cells are not strong enough to hurt people, instead they feel sticky like velcro. Sea anemones do have stinging cells, but their sting is so light and we have layers of dead skin on our fingers to protect us, so even though they are trying to sting us, we can’t feel it. They just feel sticky! Come and touch our sticky friends at the Roundhouse Aquarium’s touch tank!Sea urchins are covered with long, sharp, sometimes venom-coated spines. Touching or stepping on these spines typically causes a painful puncture wound. The spines commonly break off in the skin and cause chronic pain and inflammation if not removed. Joint and muscle pain and rashes may develop.Kanani assures that, with treatment, the pain and symptoms of a sea urchin sting should subside within five days. However, complications are possible, especially if the venom penetrates deeply. For example, tissue necrosis (the death of body tissue) can lead to arthritis and joint stiffness.Sea anemone stings typically occur when they are accidentally brushed up against or purposely touched by the unknowing. Initial symptoms vary from a prickly sensation to severe burning at the wound site.You probably won’t get stung if you lightly touch a sea urchin, but if you make contact with any amount of pressure, like if you step on a sea urchin, the sea urchin’s pedicellariae will likely sting you and release venom. Sea urchin stings aren’t usually fatal, but they are dangerous.

While the toxin isn’t dangerous for humans, we’d still recommend that you refrain from touching anemones while diving. The main components found in sea anemone venom are traditionally grouped into four functional types: (1) phospholipase A2 that degrades membrane phospholipids of neuronal and muscle cells, causing nerve damage and muscle inflammation [24]; (2) cytolysins that act on cell membranes and cause cell lysis [25]; (3) .Sea anemones produce venoms of exceptional molecular diversity, with at least 17 different molecular scaffolds reported to date. These venom components have traditionally been classified according to pharmacological activity and amino acid sequence.
