Exaiptasia diaphana, the pale anemone, is a species of sea anemone in the genus Exaiptasia . [1] [2]
The blennioid family Chaenopsidae includes the pike-blennies, tube-blennies, and flagblennies, all percomorph marine fish in the order Blenniiformes. The family is strictly tropical, ranging from North to South America. Members are also present in waters off Japan, Taiwan and Korea. Fourteen genera and 91 species are represented, the largest being the sarcastic fringehead, Neoclinus blanchardi, at 30 cm (12 in) in length; most are much smaller, and the group includes perhaps the smallest of all vertebrates, Acanthemblemaria paula, measuring just 1.3 cm (0.51 in) long as an adult.
Hexacorallia is a class of Anthozoa comprising approximately 4,300 species of aquatic organisms formed of polyps, generally with 6-fold symmetry. It includes all of the stony corals, most of which are colonial and reef-forming, as well as all sea anemones, and zoanthids, arranged within five extant orders. The hexacorallia are distinguished from another class of Anthozoa, Octocorallia, in having six or fewer axes of symmetry in their body structure; the tentacles are simple and unbranched and normally number more than eight. These organisms are formed of individual soft polyps which in some species live in colonies and can secrete a calcite skeleton. As with all Cnidarians, these organisms have a complex life cycle including a motile planktonic phase and a later characteristic sessile phase. Hexacorallia also include the significant extinct order of rugose corals.
Aiptasia is a genus of a symbiotic cnidarian belonging to the class Anthozoa. Aiptasia is a widely distributed genus of temperate and tropical sea anemones of benthic lifestyle typically found living on mangrove roots and hard substrates. These anemones, as well as many other cnidarian species, often contain symbiotic dinoflagellate unicellular algae of the genus Symbiodinium living inside nutritive cells. The symbionts provide food mainly in the form of lipids and sugars produced from photosynthesis to the host while the hosts provides inorganic nutrients and a constant and protective environment to the algae. Species of Aiptasia are relatively weedy anemones able to withstand a relatively wide range of salinities and other water quality conditions. In the case of A. pallida and A. pulchella, their hardiness coupled with their ability to reproduce very quickly and out-compete other species in culture gives these anemones the status of pest from the perspective of coral reef aquarium hobbyists. These very characteristics make them easy to grow in the laboratory and thus they are extensively used as model organisms for scientific study. In this respect, Aiptasia have contributed a significant amount of knowledge regarding cnidarian biology, especially human understanding of cnidarian-algal symbioses, a biological phenomenon crucial to the survival of corals and coral reef ecosystems. The dependence of coral reefs on the health of the symbiosis is dramatically illustrated by the devastating effects experienced by corals due to the loss of algal symbionts in response to environmental stress, a phenomenon known as coral bleaching.
Sea anemones are a group of predatory marine invertebrates constituting 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.
Baeoentedon is a genus of hymenopteran insects of the family Eulophidae, they are parasitoids of whitefly from the family Aleyrodidae which are found on trees of the genus Ficus. They have been recorded from Australia, China, India, Indonesia and Florida. A fifth species, Baeoentodon farazi, was described from Karnataka, India, in 2017.
Nepotilla is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.
Milnesium is a genus of tardigrades. It is rather common, being found in a wide variety of habitats across the world. It has a fossil record extending back to the Cretaceous, the oldest species found so far is known from Turonian stage deposits on the east coast of the United States. Milnesiums are one of the most desiccation and radiation-resistant invertebrates on Earth because of their unique ability to transform into a "tun" state and utilize intrinsically disordered proteins when experiencing extreme environments.
Aiptasia diaphana, commonly known as the yellow aiptasia or glasrose, is a species of sea anemone native to shallow waters in the temperate eastern Atlantic Ocean and the Mediterranean Sea. It has been introduced into the Red Sea.
Exaiptasia is a genus of sea anemone in the family Aiptasiidae, native to shallow waters in the temperate western Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico. It is monotypic with a single species, Exaiptasia diaphana, and commonly known as the brown anemone, glass anemone, pale anemone, or simply as Aiptasia.
Arxellia is a genus of sea snails, marine gastropod mollusks, in the family Solariellidae.
Arxellia erythrea is a species of sea snail, a marine gastropod mollusk, in the family Solariellidae.
Arxellia helicoides is a species of sea snail, a marine gastropod mollusk, in the family Solariellidae.
Arxellia tenorioi is a species of sea snail, a marine gastropod mollusk, in the family Solariellidae.

Shuqiang Li is a Chinese arachnologist and a professor at the Institute of Zoology of the Chinese Academy of Sciences. Li is best known for his work with spiders and has described hundreds of new species and many genera. He is Editor in Chief of the journal Zoological Systematics.
Diaphana minuta is a species of gastropods belonging to the family Diaphanidae.
Ecnomiohyla bailarina, the golden-eyed fringe-limbed tree frog, is a frog in the family Hylidae, endemic to Panama and Costa Rica. Scientists have seen it between 400 and 1400 meters above sea level. It lives in the Talamanca Mountains in Costa Rica and in Santa Fé National Park in Panama.
Ecnomiohyla veraguensis is a frog that lives in Costa Rica and Panama. Scientists have seen it at 540 meters above sea level. It lives in the Talamanca Mountains in Costa Rica and in Santa Fé National Park in Panama.
Baeoentedon bouceki is a species of wasp, one of the first three members of the genus Baeoentedon to be discovered in China. It is less than a millimetre in length, with a head slightly wider than the middle portion of the body. Only one specimen has been studied, collected from Hainan in 1983. As that specimen is female, the appearance of males is unknown.
Brockphasma is currently a monotypic genus of Asian stick insects in the tribe Necrosciini, erected by G.W.C. Ho, Liu, Bresseel & Constant in 2014. To date, one species has been recorded from Vietnam.
