Needle augers [Acus]

Description

Acus, commonly referred to as needle augers, comprises a group of marine snails with exceptionally slender and elongated shells, often possessing an almost needle-like appearance. These gastropods are adept burrowers, inhabiting sandy and muddy substrates in tropical and subtropical oceans. Their diet primarily consists of small invertebrates, which they capture using a venomous apparatus. The shells of Acus species are characterized by their smooth or lightly ornamented surface and a pointed apex, embodying a simplistic yet functional design suited to their burrowing lifestyle.
