Edwardsia neozelanica, commonly known as the burrowing anemone, is a small cryptic sea anemone from New Zealand. It burrows into soft mud or sand, and when covered with water extends its tentacles to feed on tiny particles of detritus.
E. neozelanica is found in New Zealand, in intertidal areas such as harbour mouths or rock pools where silt and mud accumulates. [1] Being small and so similar in colour to the substrate it lives in, E. neozelanica is a cryptic species most often found when sand or mud is passed through a fine sieve. [1]
This tiny anemone has a diameter of just 5 millimetres and a length of 30–50 millimetres. [2] [3] Its long worm-like body is divided into three parts: physa, scapus, and capitulum. The physa is a bulbous bladder-like organ covered with tiny suckers, used in burrowing. [4] The scapus or body column is wrinkly and covered with a rough cuticle that can be brown, grey, or orange in colour, with a narrow neck at the top connecting it to the capitulum or oral end. [4]
E. neozelanica has on its capitulum sixteen or more transparent tentacles, usually in two whorls of eight, that are pinkish white to buff yellow or brown in colour. [3] [4] Each tentacle in the outer whorl corresponds with one of eight brown lines that originate on the scapus as longitudinal double white lines.
This worm-like sea anemone thrusts its body into soft mud or sand before anchoring itself in place by slightly swelling its body column. [3] Only its oral disc and tentacles are visible above the silt. It feeds on organic detritus, extending its fine tentacles across the surface of the sediment. [3]
The starlet sea anemone is a species of small sea anemone in the family Edwardsiidae native to the east coast of the United States, with introduced populations along the coast of southeast England and the west coast of the United States. Populations have also been located in Nova Scotia, Canada. This sea anemone is found in the shallow brackish water of coastal lagoons and salt marshes where its slender column is usually buried in the mud and its tentacles exposed. Its genome has been sequenced and it is cultivated in the laboratory as a model organism, but the IUCN has listed it as being a "Vulnerable species" in the wild.
Ivell's sea anemone is a species of sea anemone in the family Edwardsiidae. It is endemic to a single location, Widewater Lagoon in West Sussex, England, where it was first discovered by Richard Ivell. It has been listed as Data Deficient by the IUCN since 1996.
Sea anemones are a group of predatory marine organisms of the order Actiniaria. Because of their colourful appearance, they are named after the anemone, a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and Hydra. Unlike jellyfish, sea anemones do not have a medusa stage in their life cycle.
Nembrotha lineolata is a species of nudibranch, a sea slug, a marine gastropod mollusk in the family Polyceridae. It is found in shallow water in the Indo-Pacific. It was first described in 1905 by the Danish malacologist Rudolph Bergh. The type locality is Selayar Island, Indonesia.
Actinia tenebrosa, commonly named Waratah anemone, is the most common species of sea anemone found in the waters of eastern Australia and New Zealand. It is found relatively high on the seashore, in rock pools, and various cracks and shaded surfaces such as under rock overhangs in the intertidal zone.
Peachia is a genus of sea anemone in the family Haloclavidae. Members of this genus typically burrow into soft substrates. The only part of the animal that is normally visible is the oral disc and tentacles which lie flat on the sand in a star shape. The type species is Peachia cylindrica.
Peachia cylindrica is a large species of sea anemone in the family Haloclavidae. It is normally found burrowed into soft substrates, the only visible part of the animal being the oral disc and tentacles which usually lie flat on the sand. It is the type species of the genus Peachia.
Cerianthus lloydii is a species of tube-dwelling sea anemone in the family Cerianthidae. It is sometimes called the lesser cylinder anemone and is found in shallow seas around the coasts of north west Europe.
Cerianthus membranaceus, the cylinder anemone or coloured tube anemone, is a species of large, tube-dwelling anemone in the family Cerianthidae. It is native to the Mediterranean Sea and adjoining parts of the northeastern Atlantic Ocean.
Haloclava producta is a species of sea anemone in the family Haloclavidae, commonly known as the ghost anemone. This species is native to shallow water in the northwestern Atlantic Ocean, between Cape Hatteras and the Bay of Fundy, where it makes a temporary burrow in soft sediment. It is found on sand flats, both intertidally and subtidally.
Paranthus rapiformis, the onion anemone, is a species of sea anemone in the family Actinostolidae. It was first described by the French naturalist Charles Alexandre Lesueur in 1817 and is native to the northwestern Atlantic Ocean and the Gulf of Mexico.
Metridium canum is a species of sea anemone in the family Metridiidae. It is found in the southwestern Pacific Ocean and the seas off New Zealand.
Corynactis viridis, the jewel anemone, is a brightly coloured anthozoan similar in body form to a sea anemone or a scleractinian coral polyp, but in the order Corallimorpharia. It is found in the northeastern Atlantic Ocean and the Mediterranean Sea and was first described by the Irish naturalist George Allman in 1846.
Mesacmaea mitchellii is a species of sea anemone in the family Haloclavidae. It is found in the northeastern Atlantic Ocean and the Mediterranean Sea where it burrows in soft sediment.
Cricophorus nutrix, commonly known as the brooding or nurseanemone, is a species of sea anemone endemic to New Zealand.
Oulactis magna, commonly known as the giant shore anemone or camouflaged anemone, and by its Māori name kōtore tino nui, is a common sea anemone found in New Zealand.
Anthopleura rosea, commonly known as the rose anemone or rock pool anemone, is a small pink anemone endemic to New Zealand.
Edwardsia delapiae is a species of sea anemone which is currently only known from its type locality in South-West Ireland.
Actinostella flosculifera, the collared sand anemone, is a species of sea anemone in the family Actiniidae. It is found semi-immersed in the sediment in shallow water in the tropical and subtropical Atlantic Ocean.
Edwardsia timida, also known as the timid burrowing anemone, is a species of sea anemone in the family Edwardsiidae.
