Agaronia gibbosa

The shell of this species measures 40-75 mm in length.[3]

Agaronia gibbosa is variable in shape, but large specimens tend to be distinguished from other Agaronia by the large spire callus and bulbous shape (most Agaronia are narrower and rather bullet-shaped). In its natural state, the shell of Agaronia gibbosa is usually a blotched greenish color with a striped yellow band at the siphonal end, though the species also comes in an all-yellow variety. This species is common in the shell trade and it is common for the outer layer of the shell to be polished away, revealing a brownish-black color underneath.[4]

Populations of 'this marine species' are found in the Indian Ocean, typically near the shores of the Indian sub-continent and Indonesia.[5]
