Keyhole limpets is the common name for the taxonomic family Fissurellidae, a group of limpet-like sea snails, marine gastropod molluscs in the superfamily Fissurelloidea.

[edit] Distribution
Keyhole limpets live world-wide: in cold waters, warm waters, and in tropical waters.
[edit] Habitat
Fissurellids live on and under rocks, in the lower intertidal zones and also in deeper waters.
[edit] Shell description
Keyhole limpets somewhat resemble true limpets because of their simple conical shells, but in reality they are not closely related to true limpets, which are in the order Patellogastropoda.
For respiration,the shells of fissurellids have an apical perforation, marginal slit, notch, or internal groove. This allows a direct exit of exhalant water currents from the mantle cavity.
In addition keyhole limpets differ in several other ways both internally and externally from true limpets.
