Ovulidae usually have plain shells and brightly coloured mantles.
The Cowries are probably the most admired and sought after by shell collectors.
Cowries have few predators, but the mollusc-eating cones like Conus textile and octopus can inject venom into the cowry's flesh through a small hole and then sucks out the contents. Ref: x
