Astrophyton
The giant basket star, ''Astrophyton muricatum'', is an echinoderm found in shallow parts of the tropical western Atlantic and throughout the Caribbean Sea and the Gulf of Mexico. It is the only species in the genus ''Astrophyton''. During the day, it curls up into a tight ball shape to protect itself from predators. At night, it climbs to an elevated point to feed by extending its intricately branched feeding arms in a bowl-like shape in order to snare passing plankton and other organisms from the current. Description The giant basket star is a very large echinoderm that can reach a diameter of nearly a metre when its arms are fully extended. It has a central disc and eight slender, flexible arms that repeatedly divide to form a fine-meshed net-like structure. The colour is generally brown or black. Distribution and habitat This basket star is found in warmer regions of the western Atlantic Ocean, the Caribbean Sea and Gulf of Mexico. Its range extends from Cape Lookout in Nort ...

Gorgonocephalidae
Gorgonocephalidae is a family of basket stars. They have characteristic many-branched arms. Gorgonocephalidae are the largest ophiuroids ('' Gorgonocephalus stimpsoni'' can measure up to 70 cm in arm length with a disk diameter of 14 cm). Systematics and phylogeny The family is divided into the following genera: Fossil record of Gorgonocephalidae dates back to Miocene The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recen ....Kroh, A. 2003.

James Henry Fleming
James Henry Fleming (Toronto, July 5, 1872 – June 27, 1940) was a Canadian ornithologist. His father was Scottish, and sixty years old when his son was born. James became interested in birds at the age of 12. He was an associate member of the Royal Canadian Institute at 16. In 1916, he became a fellow of the American Ornithologists' Union (AOU), and by 21 was an associate member. He eventually became its president, holding the post from 1932 to 1935. His standing as an ornithologist was recognized in many ways. The National Museum of Canada made him honorary curator of ornithology in 1913. He was elected British Empire Member of the British Ornithological Union; Corresponding Member of the Zoological Society of London; and Membre d'Honneur Étranger of the Société Ornithologique et Mammalogique de France. He was an honorary (but active) member of the Brodie Club, Toronto Toronto ( ; or ) is the capital city of the Canadian province of Ontario. With a recorded popul ...

Jean-Baptiste Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with Naturalism (philosophy), natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine.#Packard, Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French Nationa ...

Basket Star
The Euryalida are an order of brittle stars, which includes large species with either branching arms (called "basket stars") or long and curling arms (called "snake stars"). Characteristics Many of the species in this order have characteristic repeatedly branched arms (a shape known as "basket stars", which includes most Gorgonocephalidae and two species in the family Euryalidae), while the other species have very long and curling arms, and go rather by the name of "snake stars" (mostly abyssal species). Many of them live in deep sea habitats or cold waters, though some basket stars can be seen at night in shallow tropical reefs. Most young basket stars live on specific type of coral. In the wild they may live up to 35 years. They weigh up to Like other echinoderms, basket stars lack blood and achieve gas exchange via their water vascular system. The basket stars are the largest ophiuroids with '' Gorgonocephalus stimpsoni'' measuring up to 70 cm in arm length with ...

Echinoderm
An echinoderm () is any member of the phylum Echinodermata (). The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest entirely marine phylum. The first definitive echinoderms appeared near the start of the Cambrian. The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single limb. ...

Caribbean Sea
The Caribbean Sea ( es, Mar Caribe; french: Mer des Caraïbes; ht, Lanmè Karayib; jam, Kiaribiyan Sii; nl, Caraïbische Zee; pap, Laman Karibe) is a sea of the Atlantic Ocean in the tropics of the Western Hemisphere. It is bounded by Mexico and Central America to the west and southwest, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the northern coast of South America. The Gulf of Mexico lies to the northwest. The entire area of the Caribbean Sea, the numerous islands of the West Indies, and adjacent coasts are collectively known as the Caribbean. The Caribbean Sea is one of the largest seas and has an area of about . The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, Gulf of Venezuela, Gulf of Darién, Golfo de los Mosquitos, Gulf of Paria and Gulf of Honduras. The Caribbean Sea has ...

Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

Plankton
Plankton are the diverse collection of organisms found in Hydrosphere, water (or atmosphere, air) that are unable to propel themselves against a Ocean current, current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air ...

Cape Lookout (North Carolina)
Cape Lookout is the southern point of the Core Banks, one of the natural barrier islands on the Atlantic coast of North Carolina. It delimits Onslow Bay to the west from Raleigh Bay to the east. Core Banks and Shackleford Banks have been designated as parts of the Cape Lookout National Seashore. Part of Carteret County, the cape sits 11 miles southeast of Beaufort. It is one of the state's three major capes, along with Cape Hatteras to the north and Cape Fear to the south. The 163-foot Cape Lookout Lighthouse sits about three miles northeast of the cape's point. Climate According to the Trewartha climate classification system, Cape Lookout, North Carolina has a humid subtropical climate with hot and humid summers, cool winters and year-around precipitation (''Cfak''). Cfak climates are characterized by all months having an average mean temperature > 32.0 °F (> 0.0 °C), at least eight months with an average mean temperature ≥ 50.0 °F (≥ 10.0 °C), a ...

Seagrass Meadow
A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries. Seagrasses are flowering plants with stems and long green, grass-like leaves. They produce seeds and pollen and have roots and rhizomes which anchor them in seafloor sand. Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world. They provide habitats and food for a diversity of marine life comparable to that of coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs. They function as nursery habitats for shrimps, scallops and many commercial fish species. Seagrass meadows provide coastal storm protection by the way their leaves absorb energy from waves as they hit the coast. They keep coastal waters healthy ...
