The Scorpaeniformes are a diverse order of ray-finned fish, including the lionfishes and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320.
Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, which produces planula larvae that disperse widely and enter a sedentary polyp phase before reaching sexual maturity.
Microlophus is a genus of tropidurid lizards native to South America. Around 20 species are recognized and 10 of these are endemic to the Galápagos Islands, where they are commonly known as lava lizards. The remaining, which often are called Pacific iguanas, are found in the Andes and along the Pacific coasts of Chile, Peru, and Ecuador.
The lion's mane jellyfish, also known as the giant jellyfish, arctic red jellyfish, or the hair jelly, is one of the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans. It is common in the English Channel, Irish Sea, North Sea, and in western Scandinavian waters south to Kattegat and Øresund. It may also drift into the southwestern part of the Baltic Sea. Similar jellyfish – which may be the same species – are known to inhabit seas near Australia and New Zealand. The largest recorded specimen was measured off the coast of Massachusetts in 1865 and had a bell with a diameter of 210 centimetres and tentacles around 36.6 m (120 ft) long. Lion's mane jellyfish have been observed below 42°N latitude for some time in the larger bays of the east coast of the United States.
Bivalvulida is an order of myxosporean parasites which contains a number of species which cause economically significant losses to aquaculture and fisheries, such as Myxobolus cerebralis and Ceratomyxa shasta. The Myxosporean stages of members of the bivalvulida are characterised by their two spore valves, which meet in a "suture line" which encircles the spore. They usually contain two polar capsules, but species have been reported which contain either one or four.
Cybaeidae is a family of spiders first described by Nathan Banks in 1892. The diving bell spider or water spider Argyroneta aquatica was previously included in this family, but is now in the family Dictynidae.
Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jellyfish found worldwide in temperate to tropic waters. It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual. Others include the jellyfish Laodicea undulata and species of the genus Aurelia.
Pagurus is a genus of hermit crabs in the family Paguridae. Like other hermit crabs, their abdomen is not calcified and they use snail shells as protection. These marine decapod crustaceans are omnivorous, but mostly prey on small animals and scavenge carrion. Trigonocheirus and Pagurixus used to be considered subgenera of Pagurus, but the former is nowadays included in Orthopagurus, while the latter has been separated as a distinct genus.
Allen's yellow bat is a species of vesper bat. There is some taxonomic debate surrounding this species, with some authors considering Baeodon a genus rather than a subgenus. It is endemic to Mexico.
Hyperolius molleri is a species of frog in the family Hyperoliidae. It is endemic to São Tomé Island. Records from Príncipe now refer to Hyperolius drewesi, described as a distinct species in 2016.
Bela is a genus of sea snails; marine gastropod mollusks in the family Mangeliidae.
Rissoa is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
Acanthocidaris hastigera is a species of sea urchin of the family Cidaridae. Their armour is covered with spines. It is in the genus Acanthocidaris and lives in the sea. Acanthocidaris hastingeria was first scientifically described in 1907 by Alexander Emanuel Agassiz & Hubert Lyman Clark.
Acanthocidaris maculicollis is a species of sea urchin of the family Cidaridae. Their armour is covered with spines. It came from the genus Acanthocidaris and lives in the sea. Acanthocidaris hastingeria was first scientifically described in 1904 by de Meijere.
Zebrida adamsii is a distinctively striped species of crab that lives in association with a sea urchin in the Indo-Pacific region. It is cryptically coloured with vertical stripes and has special adaptations to its legs to enable it to cling to its host's spines.
Omoglymmius is a genus of wrinkled bark beetles in the family Carabidae, found on every continent except Africa and Antarctica. There are at least 150 species in Omoglymmius.
Cassiopea xamachana, commonly known as the upside-down jellyfish, is a species of jellyfish in the family Cassiopeidae. It is found in warm parts of the western Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. It was first described by the American marine biologist Henry Bryant Bigelow in 1892.
Muggiaea atlantica is a species of small hydrozoan, a siphonophore in the family Diphyidae. It is a cosmopolitan species occurring in inshore waters of many of the world's oceans, and it has colonised new areas such as the North Sea and the Adriatic Sea. It is subject to large population swings, and has been held responsible for the death of farmed salmon in Norway. The species was first described by J.T. Cunningham in 1892 from a specimen obtained at Plymouth, England.
The Sea Transport Branch of the British Board of Trade, originally established as the Transport Department or Naval Transport Department, was a logistical branch of the Department of Admiralty responsible for the provision of naval transportation services. It underwent numerous name changes throughout its complicated history with responsibility for sea transportation, known as the Department of the Director of Transports from 1890.
Acanthocidaris is a genus of echinoderms belonging to the family Cidaridae.
