Introduction
All mussels have two shells, they are connected with flexible bands.
Most are filter feeders, buried in the sand or with a shell attached to a rock.
Only a few can swim.
Ctenoides scaber
Flame scallop
Size: 6 - 7 cm
Luminescent to orange-red mantle.
In shallow water the tentacles are often reddish-orange ( photo 2 -3 ),
in deeper water they are white ( photo 1 ).
The shell halves are whitish to brownish in colour and have many fine radial ribs.
The mussel is able to swim independently in jerky movements
and occasionally seeks out locations behind stones.

Pedum spondyloideum
Iridescent clam, Coral clam or Coral scallop
Size: 3 - 6 cm
In nature, it is found exclusively in living corals,
where it settles and grows.
It attaches itself to the calcareous skeleton of the coral with byssus threads
and is overgrown by these, so that only the shell openings are visible.
