Haustrum haustorium, common name: the brown or dark rock shell, is a large species of predatory sea snail, a marine gastropod mollusc in the family Muricidae, the murex snails or rock snails.
Haustrum haustorium used to be the only species in the genus Haustrum . However, Beu (2004) reclassified a number of New Zealand's whelks, considering species in the genus Lepsiella to be synonymous with the genus Haustrum.
This species occurs in New Zealand.
A reliable characteristic for distinguishing Haustum haustorium from its congeners is the angle by which the aperture lip inserts on the shell: In Haustrum haustorium the angle is near-perpendicular, whereas in other species the angle is more acute (~45 degrees). Tan (2003) provides the most recent review.
This rock snail's typical habitat is the mid and lower eulittoral zone of New Zealand's semi-exposed rocky intertidal shores. It is less common on algal-dominated sheltered shores.
Poirieria is a genus of large predatory sea snails, marine gastropod molluscs in the subfamily Pagodulinae of the family Muricidae, the rock snails.
Poirieria zelandica, common name the spiny murex, is a species of large predatory sea snail with an operculum. It is a marine gastropod mollusc in the family Muricidae, the rock snails or murex snails.
Dicathais is a genus of predatory sea snails, marine gastropod molluscs in the family Muricidae, the rock snails. This genus is monotypic; the only species in it is Dicathais orbita, common name the white rock shell or cart-rut shell, found round the coasts of Australia and New Zealand.
Haustrum is a genus of sea snails, marine gastropod mollusks in the subfamily Haustrinae of the family Muricidae, the murex snails or rock snails.
Sigapatella is a genus of small to medium-sized sea snails, marine gastropod molluscs in the family Calyptraeidae, the slipper snails, Chinese hat snails, and cup-and-saucer snails.
Zeatrophon ambiguus common name the large trophon, is a species of large predatory sea snail, a marine gastropod mollusc in the family Muricidae, the rock snails or murex snails.
Zeatrophon pulcherrimus is a species of small predatory sea snail, a marine gastropod mollusc in the family Muricidae, the rock snails or murex snails.
Axymene traversi is a species of predatory sea snail, a marine gastropod mollusc in the family Muricidae, the rock snails or murex snails.
Axymene aucklandicus is a species of predatory sea snail, a marine gastropod mollusc in the family Muricidae, the rock snails or murex snails.
Buccinulum is a genus of sea snails, marine gastropod molluscs in the family Buccinidae, the true whelks.
Aeneator is a genus of sea snails, marine gastropod molluscs in the family Buccinidae, the true whelks.
Zegalerus is a genus of small to medium-sized sea snails, marine gastropod molluscs in the family Calyptraeidae, commonly known as slipper snails, cup-and-saucer shells, and Chinese hat shells.
Glaphyrina plicata is a species of large sea snail, a marine gastropod mollusc in the family Fasciolariidae.
Buccinulum vittatum is a species of sea snail, a marine gastropod mollusc in the family Buccinidae.
Lunella smaragda, common name the cat's eye snail, is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.
Haustrum lacunosum is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
Haustrum scobina, or the oyster borer, is a species of predatory sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails. Oyster borers use a mucous layer that surrounds the entrance to their shell to prevent desiccation in the midlittoral and high tidal zones. Oyster Borers are frequently found in crevices which have more protection from predators, higher water availability, lower temperature, extremes in salinity and protection from the sun and wind.
Murexsul octogonus, or the octagonal murex, is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
Prototyphis eos is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
Agnewia is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.
