slit limpet

#900 - Diodora lineata - Common Keyhole Limpet

Resembling a True Limpet, but unrelated. This Keyhole or Slit Limpets suck in water around the edge of the shell and exhale it through the keyhole or slit. Most species feed on algae, but some, including certain Diodora, prey on sponges. I don’t know if this is one of the carnivorous species.

The Fissurellidae are found on and under rocks in oceans worldwide, but this species is found on Australia’s eastern coasts.
