| Cricophorus nutrix (Stuckey, 1909) | |
Cricophorus nutrix, commonly known as the brooding or nurseanemone, is a species of sea anemone endemic to New Zealand. [1]
It is found living in colonies on the stem of large seaweed and kelp species in the low tidal zone. [2] It can also live in deep tidal pools where seaweed is present. [3]
This small anemone has a diameter of 10–15 millimetres [3] with a range of colours that can appear to be iridescent. [2]
When underwater it extends short, fine, smooth tentacles that are 2–5 millimetres long with rounded tips. These are arranged in three to four crowded whorls along the edge of the disc. [2] The inner tentacles can be twice as long as the outer tentacles. [4] Tentacle colour can range between light yellow and deep brown and often feature green, blue or red tinges. [3] Its central disc can be a similar colour to the tentacles or a contrasting colour such as white, purple or orange and usually features radial markings. [2] Its mouth can be light blue, bright pink or purple, and often has a lighter colour on the interior. [3] The anemone's column is usually a deep brown colour, but can also be green, blue, or yellow. [2]
Out of water, the tentacles retract and the anemone camouflages itself against the plant it is attached to. [3]
Brooding anemone release long, white threads of stinging cells when it is disturbed. This is a defence mechanism to deter attackers. [3]
Heteractis magnifica, also known by the common names magnificent sea anemone or Ritteri anemone, is a species of sea anemone belonging to the Stichodactylidae family native to the Indo-Pacific area.
The dahlia anemone is a sea anemone found in the north Atlantic Ocean, the North Sea and the Baltic Sea. Its colour is variable, from deep red to brown or purplish, with green spots and darker tentacles. Dahlia anemones live attached to rock on the seabed from the lower tidal limit down to a depth of 100 m and also attached to other organisms. Their diet comprises small fish and crustaceans, which they immobilize by firing groups of stinging cells (cnidae) into them. Dahlia anemones are closely related to mottled anemones, and both species are usually referred to as northern red anemones.
Sea anemones are the marine, predatory animals of the order Actiniaria. They are named after the anemone, a terrestrial flowering plant, because of the colourful appearance of many. 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.
Condylactis gigantea is a tropical species of ball anemone that is found in shallow reefs and other shallow inshore areas in the Caribbean Sea – more specifically the West Indies – and the western Atlantic Ocean including southern Florida through the Florida Keys. It is also commonly known as: giant Caribbean sea anemone, giant golden anemone, condylactis anemone, Haitian anemone, pink-tipped anemone, purple-tipped anemone, and Florida condy. This species can easily be seen growing in lagoons or in inner reefs as either individuals or loose groups, but never as colonies. They are often used as a model organism along with others in their genus for facultative symbiosis with monocellular algae.
Phymanthus crucifer, commonly known as rock flower anemone, flower anemone, red beaded anemone or the beaded anemone, is a species of sea anemone in the family Phymanthidae. It has been described as "closely similar" to Heteractis aurora in several ways, commonly exhibiting "tentacles with swollen cross-bars" bearing large clusters of stinging nematocysts. However, P. crucifer may also be found with smooth tentacles, sometimes in the immediate vicinity of a swollen-crossbarred specimen.
Actinoporus elegans, commonly known as the elegant anemone or the brown-striped anemone, is a species of sea anemone in the family Aurelianidae. This species may exhibit a high degree of colour variability, from blue to white to nearly transparent.
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.
Epiactis prolifera, the brooding, proliferating or small green anemone, is a species of marine invertebrate in the family Actiniidae. It is found in the north-eastern Pacific. It has a feature rare among animals in that all individuals start life as females but develop testes later in their lives to become hermaphrodites.
Sagartia troglodytes is a species of sea anemone in the family Sagartiidae, also known as the mud sagartia or the cave-dwelling anemone.
Metridium farcimen is a species of sea anemone in the family Metridiidae. It is commonly known as the giant plumose anemone or white-plumed anemone. It is found in the eastern Pacific Ocean from Alaska down to Catalina Island, California.
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.
Oulactis muscosa, also known as the sand anemone and speckled anemone, is a species of sea anemone in the family Actiniidae.
Condylactis aurantiaca, commonly known as the golden anemone, is a species of sea anemone in the family Actiniidae. This species always remains largely buried in sand or sediment, attached to the substrate, with only the oral disc and tentacles visible.
The Enthemonae is a suborder of sea anemones in the order Actiniaria. It comprises those sea anemones with typical arrangement of mesenteries for actiniarians.
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.
Epiactis fernaldi, commonly known as the Fernald brooding anemone, is a species of sea anemone in the family Actiniidae. It is native to shallow waters around the San Juan Islands off the western coast of North America.
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.
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.
