Sabia australis is a small limpet-like species of sea snail, belonging to the marine gastropod family Hipponicidae, also known as hoof snails. [1]
Sabia australis typically possesses a conical shell, with colors ranging from white to yellow or orange. [2] The surface of its shell is usually rough and textured, providing protection against environmental circumstances and serving as camouflage against predators. The size of its shell varies depending on factors such as age and environmental conditions, but typically reaches up to 30 millimeters in length. [3]
Sabia australis exhibits protandric hermaphroditism. [4] Female Sabia australis lay up to 10 eggs, primarily during winter, each egg containing 9 to 24 embryos that hatch into crawling juveniles. [4] These juveniles then drift or swim to find a host to settle on, often clustering on a single host. [4] [5] Sabia australis is a bisexual species, with its sexual development influenced by the proximity of conspecifics. [4] For example, if it settles on a host alone, it quickly develops into a female, with its male phase being very short or nonexistent. However, if it settles next to a female, it develops into a male and lives on the back of a female. [4]
Sabia australis inhabits the shells of other mollusks and feeds on their fecal pellets. [4] It typically positions itself on the shell area with direct access to its host's excretions. [4]
This species is native to southeastern and southwestern Australia, including New South Wales, Tasmania, Victoria, Southern Australia, and Western Australia, where it is widespread and common. [2] It is widespread and commonly found in Tasmanian waters. [2] Sabia australis is considered cryptogenic to O'ahu, Hawai'i. [6]
Sabia australis is found in the intertidal zone and shallow waters. [3]
The Tasmanian giant crab, also known as the giant deepwater crab, giant southern crab, queen crab, or bullcrab, is a very large species of crab that resides on rocky and muddy bottoms in the oceans off Southern Australia. It is the only extant species in the genus Pseudocarcinus.
Asterias amurensis, also known as the Northern Pacific seastar and Japanese common starfish, is a seastar found in shallow seas and estuaries, native to the coasts of northern China, Korea, far eastern Russia, Japan, Alaska, the Aleutian Islands and British Columbia in Canada. Two forms are recognised: the nominate and formarobusta from the Strait of Tartary. It mostly preys on large bivalve molluscs, and it is mostly preyed on by other species of starfish. Population booms in Japan can affect the harvest of mariculture operations and are costly to combat.
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.
Hippopus hippopus, also known as the Horse Hoof clam and Strawberry clam, is a species of giant clam in the Subfamily Tridacninae and the genus Hippopus. Hippopus is a delicacy in many Southeast Asian countries due to its high quality meat.
Tridacna crocea, the boring clam, crocus clam, crocea clam or saffron-coloured clam, is a species of bivalve in the family Cardiidae. It is native to the Indo-Pacific region. It is occasionally found in the aquarium trade where it is often simply referred to as crocea.
Hipponicidae, common name hoof shells or hoof snails, is a family of small sea snails, limpet-like marine gastropod molluscs in the superfamily Vanikoroidea.
Hipponix, common name hoof snails or hoof shells, is a genus of small sea snails with limpet-like shells, marine gastropod molluscs in the family Hipponicidae, the hoof snails. Many of the species in this genus have white shells.
Conus textile, the textile cone or the cloth of gold cone is a venomous species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones. Textile cone snails live mostly in the Indian Ocean, along the eastern coast of Africa and around Australia.
Rochia nilotica, common name the commercial top shell, is a species of sea snail, a marine gastropod mollusk in the family Tegulidae.
Amoria undulata, common name wavy volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.
Agaronia acuminata, common name the pointed ancilla, is a species of sea snail, a marine gastropod mollusk in the family Olividae, the olive snails.
Hipponix incurvus is a species of small sea snail, a marine gastropod mollusk in the family Hipponicidae, the hoof snails. Until recently this species was considered to be a species of Capulus in the Capulidae but was reclassified by Simone (2002)
Hipponix subrufus is a species of small limpet-like sea snail, a marine gastropod mollusk in the family Hipponicidae, the hoof snails.
Sabia is a genus of small sea snails, limpet-like marine gastropod molluscs in the family Hipponicidae, the hoof shells or hoof snails.
Limacina retroversa is a distinct species of swimming planktonic gastropods, belonging to a group of predatory sea snails known as sea butterflies (Thecosomata). The name Limacina retroversa describes the unique morphology of this sea snail, including its slug-like body and coiled, backwards-turning shell. They are typically found in the epipelagic zone of cold, polar waters, but can be found worldwide, in any ocean. L. retroversa are currently under threat, as their numbers are decreasing due to rising global carbon levels and other human-caused climate threats.
Stichaster australis, the reef starfish, is a species of starfish found in the shallow waters of the rocky intertidal of New Zealand. Typically, the animal is endemic to the west coast shores of the North and South Islands, where wave action is increased. They do not usually inhabit ecosystems that have reduced wave action and calm conditions as they prefer a higher-energy environment. These marine invertebrates range in color from pink to purple, but can also be orange. They typically have eleven arms, but sometimes they may have either ten or twelve. As full-grown adults, they are 8 to 10 cm in diameter.
Austroliotia australis, commonly known as the southern liotia, is a species of sea snail, a marine gastropod mollusk in the family Liotiidae.
Oenopota gervillii is an extinct species of sea snail, a marine gastropod mollusk in the family Mangeliidae.
