Subspecies
[edit]- Agaronia acuminata acuminata (Lamarck, 1811)
- Agaronia acuminata boavistensis Burnay & Conceicao, 1986
Description
[edit]The length of the shell varies between 30 mm and 80 mm.
The smooth and glossy shell is elongate and fusiform, which means it is spindle-shaped, tapering at both ends. The spire is relatively low, compared with the overall length of the shell. The shell exhibits a range of colors: yellowish, fawn, or ash-gray, and features irregular markings, including zigzags and maculations, or is sometimes faintly nebulous with nearly obsolete markings. The suture may have fasciculations and is often reduced to a row of spots, and in some cases, it is entirely unspotted. The fasciole and fasciolar band are typically yellowish or fawn-colored, occasionally exhibiting faint, close-set, orange-red strigations. The columella is white, while the interior of the long and narrow aperture is also white, with chestnut maculations along the border of the sharp outer lip. [2]
Distribution
[edit]This species has a widespread distribution in tropical and subtropical marine environments. It occurs in the Atlantic Ocean off Gabon, Angola and West Africa;[1] also off Costa Rica, Pakistan, Sri Lanka, Indonesia and Australia. [3]
It is typically found in shallow waters, from the intertidal zone to depths of about 20 meters,
