General distribution and habitat.
Cosmopolitan in tropical to temperate seas, fouling various substrata, littoral to sublittoral (
Jones
et al
. 2000
; present study).
Descriptive features and remarks.
Specimens examined show some morphological variations. Most specimens with conic shells (
Figs
7
m, n) and typical tergum and scutum (
Figs 7
a–d). In dense clusters, shell cylindrical, but specimens within oyster populations with depressed shell, with tergum and scutum long, narrow (
Figs 7
e–h).
Exposed and eroded shells with no purple stripes externally. Tergum with spur short, round, and carinal margin rounded; scutum with articular furrow deep (
Figs
7
i–l).
Largest specimen (ZUTC-cirri 1110) with basal diameter 27.2 mm, height 11.2 mm.
This species is common in various localities along the Iranian coast, occurring in habitats with salinities ranging from 5 ppt in the Bahmanshir River, together with
A. subalbidus
(
Fig. 1
) to 43 ppt. Specimens also attach to various substrata, such as mangrove trunks and pneumatophores, human-made structures, intertidal rocks, mollusc shells, crab carapaces, ship and vessel hulls and floating objects.
