Conus planorbis Born, 1778
Planorbis cone, 75mm

Conus planorbis is a common, variable species found from the intertidal down to at least 16m on both lagoon and seaward reefs. It can be found under rocks or exposed in rocky or rubbly areas. It has long been known as Conus vitulinus, and I'm not sure if the exact ID has yet satisfactorily been worked out.

Like many cones, Conus planorbis lays its eggs capsules attached to the undersurfaces of rocks.

The one below has some characteristics of a different species, Conus circumactis, but we think ours is a variation of C. planorbis.

The color of this one resembles some forms of Conus magus.
