Razor
shell
Family Pharidae
Razor shells are usually buried in the sand in the seagrass lagoon.
However, they are sometimes spotted above ground.
Built for digging: The razor shell
is a strong and quick burrower. It has a thin and narrow shell that
slips easily through the sand. On one end is a strong foot that it
uses to burrow quickly into wet sand. On the other is a siphon that
sticks out to the surface to breathe and feed.
Razor food: Like other bivalves,
Razor shells are filter feeders. When submerged, they suck in a current
of water through their siphons and they sieve out the food particles
with their enlarged gills.
Role in the ecosystem: Like us
humans, many other animals like to eat Razor shells.
Human uses: Larger razor shells
are edible and are collected as food. |
