Limpet
Acmaea
Limpets are small sea creatures with cone-shaped shells that stick tightly to rocks along the shore. They use their strong muscular foot to cling on and protect themselves from waves and predators.
Habitat: Coastal areas
Appearance
The Limpet has a distinctive conical or cap-shaped shell, often dull grey, brown, or greenish, blending with rocky surfaces. Its shell is smooth or ribbed, and it uses a strong, muscular foot to cling tightly to rocks. It looks like a tiny, living volcano.

Interesting facts
Limpets can withstand massive wave forces, surviving extreme oceanic conditions.
Limpets return to a special 'home scar' on rocks after foraging, fitting perfectly!
Their teeth are the strongest known biological material on Earth, even stronger than Kevlar!
They breathe using gills located in a special cavity under their shell, staying moist.
Special abilities
Ability
Rock-Solid Grip
Limpet can cling incredibly tightly because of its powerful muscular foot, which creates suction against rocks.
Ability

Ability
Personal Fortress
Limpet has a tough shell that protects them from predators and prevents drying out during low tide.
