Beadlet Anemone
Actinia equinaAlso known as Beadlet Sea Anemone, Red Sea Anemone
Beadlet anemones are highly resilient predators of the intertidal zone, transforming from squishy, jelly-like blobs at low tide into beautiful, flower-like hunters when submerged. They are fiercely territorial, using a ring of bright blue, venom-packed beads called acrorhagi to sting and drive away rival anemones that encroach on their space. Uniquely adapted to survive hours of exposure to air, they trap water inside their closed bodies to prevent drying out.

Possesses mild stinging cells; avoid touching sensitive skin and wash hands after contact.
Uses stinging cells called nematocysts to paralyze prey, which can cause mild irritation or allergic reactions on sensitive human skin.
Observe without touching; if contact occurs, avoid touching your face or eyes before washing your hands.- Look for blobs: At low tide, search for what look like shiny, dark red jelly blobs clinging to vertical rock faces.
- Observe the beadlets: During high tide or in deep pools, look just below the tentacles for the bright blue beads called acrorhagi.
