Jujubinus gravinae is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.

[1] It is both a deposit feeder and grazer, feeding on organic matter particles in sediment and low-growing organisms.

[3] The animal itself has a 4mm long dextrally coiled body.

[2] It utilizes mucus-mediated gliding, the process moving forward by alternating regions of muscular contraction and expansion over a layer of mucus.

[2] This species occurs in the Western Mediterranean Sea and in the Atlantic Ocean off Portugal, the Canary Islands and the Cape Verdes.
