Deep-sea sea anemones are the "sisters" of tropical sea anemones, which live predominantly in shallower water zones.
Deep-sea sea anemones are found in all oceans and can live in extreme water depths (up to 4,000 meters) with high pressure in ice-cold water.
Unlike their tropical relatives, deep-sea anemones cannot use symbiosis with photosynthetically active endosymbionts in their completely lightless environment and rely on the capture of zooplankton and marine snow (organic tissue particles of dead organisms).
Deep-sea anemones are nowadays discovered and collected by using remotely operated underwater vehicles (ROUV).
Especially in the vicinity of the mostly unexplored deep-sea trenches and deep-sea mountains, more and more deep-sea sea anemones are currently being discovered and collected.
Sea anemones can reproduce sexually and asexually (cloning).
Brief description. Halcuria with column 49.4-73.0 mm high and 26.1-38.3 mm in diameter in preserved specimens; distal column with nematocyst batteries with only basitrichs.
Tentacles 55-70, smooth, tapering, longer than diameter of oral disc, 11-18.5 mm long in preserved specimens. Ten pairs of perfect mesenteries; microclusters in endocoels only in most distal column. Living specimens with whitish column, long, tapering, whitish translucent tentacles and bright orange mouth rising on hypostome.
Halcurias uchidai is widely distributed in deep waters (282-619 m depth) of the northwestern Atlantic Ocean, along the northern Gulf of Mexico, Florida Strait, and Little Bahamas Bank, and in northeastern mid-Atlantic canyons off the U.S. coast (Baltimore Canyon).
In the Gulf of Mexico, it has been found in deep-sea communities of Desmophyllum Ehrenberg, 1834 (formerly Lophelia Milne Edwards & Haime, 1849 ; see Hoeksema & Cairns 2022) on soft bottom or hard substrate.
