Hoplonemertea is an order of ribbon worms in the class Enopla. [1] It contains two suborders: [2] [3]
The proboscis is armed with one or more stylets; intestine straight, mostly with paired lateral diverticula; no posterior ventral sucker. [1]
Nemertea is a phylum of animals also known as ribbon worms or proboscis worms, consisting of 1300 known species. Most ribbon worms are very slim, usually only a few millimeters wide, although a few have relatively short but wide bodies. Many have patterns of yellow, orange, red and green coloration. The foregut, stomach and intestine run a little below the midline of the body, the anus is at the tip of the tail, and the mouth is under the front. A little above the gut is the rhynchocoel, a cavity which mostly runs above the midline and ends a little short of the rear of the body. All species have a proboscis which lies in the rhynchocoel when inactive but everts to emerge just above the mouth to capture the animal's prey with venom. A highly extensible muscle in the back of the rhynchocoel pulls the proboscis in when an attack ends. A few species with stubby bodies filter feed and have suckers at the front and back ends, with which they attach to a host.
The Caridea, commonly known as caridean shrimp or true shrimp, from the Greek word καρίς, καρίδος, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.
A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer usually created by an animal or organism that lives in the sea. The shell is part of the body of the animal. Empty seashells are often found washed up on beaches by beachcombers. The shells are empty because the animal has died and the soft parts have decomposed or been eaten by another animal.
FishBase is a global species database of fish species. It is the largest and most extensively accessed online database on adult finfish on the web. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications.
Carcharhiniformes, the ground sharks, are the largest order of sharks, with over 270 species. They include a number of common types, such as catsharks, swellsharks, and the sandbar shark.
Ophidiiformes is an order of ray-finned fish that includes the cusk-eels, pearlfishes, viviparous brotulas, and others. Members of this order have small heads and long slender bodies. They have either smooth scales or no scales, a long dorsal fin and an anal fin that typically runs into the caudal fin. They mostly come from the tropics and subtropics, and live in both freshwater and marine habitats, including abyssal depths. They have adopted a range of feeding methods and lifestyles, including parasitism. The majority are egg-laying, but some are viviparous.
Pillar coral is a hard coral found in the western Atlantic Ocean and the Caribbean Sea. It is the only species in the monotypic genus Dendrogyra. It is a digitate coral -that is, it resembles fingers or a cluster of cigars, growing up from the sea floor without any secondary branching. It is large and can grow on both flat and sloping surfaces at depths down to 20 m (65 ft). It is one of the few types of hard coral in which the polyps can commonly be seen feeding during the day.
The Asiatic glassfishes are a family, the Ambassidae, of freshwater and marine fishes that were formerly classified in the order Perciformes, but most authorities consider this order to be paraphyletic and that the Ambassidae are of uncertain affinities, incertae sedis, but within the subseries Ovalentaria. The species in the family are native to Asia, Oceania, the Indian Ocean, and the western Pacific Ocean. The family includes eight genera and about 51 species.
Heteroconchia is a taxonomic infraclass of diverse bivalve molluscs, belonging to the subclass Autobranchia.
Enopla is one of the classes of the worm phylum Nemertea, characterized by the presence of a peculiar armature of spines or plates in the proboscis.
The queen scallop is a medium-sized species of scallop, an edible marine bivalve mollusk in the family Pectinidae, the scallops. It is found in the northeast Atlantic and is important in fisheries.
Bodotria scorpioides is a species of crustacean belonging to the order Cumacea. They are found in the East Atlantic, the Mediterranean and the Black Sea. B. scorpioides does not possess a free telson. The first thoracic somite is too short to be seen from above, the second is longer. Both males and females have exopods on the first pereopods only.
Patella ulyssiponensis, common name the rough limpet, or China limpet is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. Despite its common name, the China limpet is found throughout the Eastern North Atlantic and the Mediterranean.
Cidaridae is a family of sea urchins in the order Cidaroida.
Poecilosclerida is an order of the demosponge class. It is the most speciose demosponge order with over 2200 species. It contains about 25 recognised families. They are characterised by having chelae microscleres, that is, the minute spicules scattered through the tissues, usually in the 10-60 μm range, have a shovel-like structure on the end.
Scorpaena scrofa, the red scorpionfish, bigscale scorpionfish, large-scaled scorpion fish, or rascasse is a venomous marine species of ray-finned fish in the family Scorpaenidae, the scorpionfishes. It is found in the Mediterranean Sea, in the eastern Atlantic Ocean and the western Indian Ocean.
A shrimp is a crustacean with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the decapod order, although some crustaceans outside of this order are also referred to as "shrimp".
Daphne Gail Fautin was an American professor of invertebrate zoology at the University of Kansas, specializing in sea anemones and symbiosis. She is world-renowned for her extensive work studying and classifying sea anemones and related species. A large sea anemone-like cnidarian species has been named in her honor, originally called Boloceroides daphneae, but recently renamed to Relicanthus daphneae, after it was discovered to belong to a previously unknown cnidarian order. Fautin has published numerous scientific articles and texts—including co-authoring Encyclopædia Britannica's entry on cnidarians—and her publications have been widely cited by other researchers in the field. Among her current positions, she is the curator of the University of Kansas Natural History Museum and serves as vice president and commissioner of the International Commission on Zoological Nomenclature, overseeing the naming of new species.
Verongiida is an order of sea sponges within the phylum Porifera. The "skeleton" in these sponges is made up of spongin, rather than of spicules. They live in marine environments. The name was proposed by Patricia Bergquist in 1978.
The Marine Policy of the Barack Obama administration comprises several significant environmental policy decisions for the oceans made during his two terms in office from 2009 to 2017. By executive action, US President Barack Obama increased fourfold the amount of protected marine space in waters under United States control, setting a major precedent for global ocean conservation. Using the U.S. president's authority under the Antiquities Act of 1906, he expanded to 200 nautical miles the seaward limits of Papahānaumokuākea Marine National Monument in Hawaiʻi and the Pacific Remote Islands Marine National Monument around the U.S. island possessions in the Central Pacific. In the Atlantic, Obama created the Northeast Canyons and Seamounts Marine National Monument, the first marine monument in the U.S. exclusive economic zone (EEZ) in the Atlantic.
