Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
Terrestrial animals are animals that live predominantly or entirely on land, as compared with aquatic animals, which live predominantly or entirely in the water, and amphibians, which rely on aquatic and terrestrial habitats. Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water.
The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".
Thylacodes zelandicus is a species of sea snail, a worm snail or worm shell, a marine gastropod mollusc in the family Vermetidae, the worm snails. This species was previously known as Serpulorbis zelandicus.
Thylacodes aotearoicus is a species of sea snail, a worm snail or worm shell, a marine gastropod mollusc in the family Vermetidae, the worm snails. This species was previously known as Serpulorbis aotearoicus.
Thylacodes squamigerus, common name the scaled wormsnail, is a species of sea snail, a marine gastropod mollusk in the family Vermetidae, the worm snails. This species was previously known as Serpulorbis squamigerus.
The Vermetoidea, the worm snails or worm shells, are a taxonomic superfamily of small to medium-sized sea snails, marine gastropod molluscs in the order Littorinimorpha.
Vermiculation is a surface pattern of dense but irregular lines, so called from the Latin vermiculus meaning "little worm" because the shapes resemble worms, worm-casts, or worm tracks in mud or wet sand. The word may be used in a number of contexts for patterns that have little in common. The adjective vermiculated is more often used than the noun.
Thylacodes arenarius is a species of sea snail, a marine gastropod mollusk in the family Vermetidae, the worm snails or worm shells.
Thylacodes decussatus is a species of sea snail, a marine gastropod mollusk in the family Vermetidae, the worm snails or worm shells. This species was previously known as Serpulorbis decussatus.
Thylacodes inopertus is a species of sea snail, a marine gastropod mollusk in the family Vermetidae, the worm snails or worm shells. This species was previously known as Serpulorbis inopertus.
Thylacodes riisei is a species of sea snail, a marine gastropod mollusk in the family Vermetidae, the worm snails or worm shells. This species was previously known as Serpulorbis riisei.
Thylacodes masier is a species of sea snail, a marine gastropod mollusk in the family Vermetidae, the worm snails or worm shells.
Petaloconchus is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells.
Vermetus is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells.
Thylacodes is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells. The species in this genus were previously placed in the genus Serpulorbis.
The common name worm-snail applies to a family and several species of gastropod:
Thylacodes sipho, the common worm-shell, is a species of sea snail, a worm shell, a marine gastropod mollusc in the family Vermetidae, the worm snails.
Thylacodes variabilis is a species of worm snail common in the rocky intertidal in Hawaiʻi and the tropical Pacific.
Michael Gale Hadfield is an invertebrate biologist and professor emeritus at the University of Hawaiʻi at Mānoa. His research has focused on the larvae of marine invertebrates and native tree snails in Hawai'i. He retired in 2013, but has remained active in research and was recognized in 2023 as one of the top ecology and evolutionary scientists in the U.S. and the world.
