Conomurex luhuanus are abundant within Marshall Islands lagoons, but are rarely found on the seaward reefs. Specimens can be found in large numbers on many shallow sand and rubble lagoon interisland reefs as well as on pinnacles at depths from about 1 to at least 16m. Sizes range up to about 60mm. Most specimens have an orange-red aperture, hence the common name. A few, however have apertures either yellow or pure white.
Both orange and white aperture specimens are shown below.

Like other Strombidae, it has a long proboscis for feeding on algae.
In the fall of 2014 there were large numbers of juveniles, mostly about the same size, on many Kwajalein lagoon reefs. There must have been a good settling shortly before.
Like some of the other strombs (e.g., Gibberulus gibbosus), this species sometimes aggregates in fairly large numbers.
