[1] Cassis flammea is found in Florida, the Caribbean, and Bahamas.

Its abundance has decreased due to overcollection in some areas.

[2] The shell may be covered by algae or other sessile marine organisms.

[3] Cassis flammea inhabits shallow tropical waters, in the depth range of 10 to 35 ft, usually in the sand around reefs.

[citation needed] The minimum recorded depth for this species is 1 m; maximum recorded depth is 12 m.[3] These sea snails feed on sea urchins, which they typically hunt at night.
