Halophila Baillonis
''Halophila baillonis'' is a species of aquatic plant in the family Hydrocharitaceae. It is referred to by the common name clover grass. It is native to Brazil, Cayman Islands, Colombia, Costa Rica, Jamaica, Leeward Islands, Netherlands Antilles, Panama, Puerto Rico, Trinidad and Tobago, and Venezuela. It is listed on the IUCN Red List as " vulnerable" due to its naturally rare occurrence and fragmented populations. Description This seagrass has fragile rhizomes with a single stem and a single root at each node. The shoots are erect and up to long, each with two obovate, keeled, scales in the central portion and a pseudo-whirl of four leaves at the tip. The leaf-blades are oblong to lanceolate, long by wide, with pronounced midribs and fine marginal serrations. There may be as many as 2,500 shoots per square metre. Distribution and habitat Clover grass is native to the Caribbean area. It is known from several sites in the Greater Antilles, Colombia, Venezuela and Bel ...

Paul Friedrich August Ascherson
Paul Friedrich August Ascherson (June 4, 1834 – March 6, 1913) was a German botanist. His author citation is ''Asch.'', although ''Aschers.'' has been used in the past. Ascherson was born in Berlin in 1834 as the son of health counsellor. In 1850, he started studying medicine at the University of Berlin, but soon started getting more interested in botany. In 1855, he received his doctorate for a dissertation about the flora of the Margraviate of Brandenburg. In the 1850s, he started to botanize in Saxony, including several excursions with Ludwig Schneider and Gustav Maass. In 1860, Ascherson became an assistant at the Botanical Garden in Berlin; in 1865 he also started working at the Royal Herbarium. In 1863, he obtained his habilitation for specific botany and plant geography. In 1873, Ascherson became associate professor at the University of Berlin. He accompanied Friedrich Gerhard Rohlfs on his 1873/74 expedition in the Libyan desert. After 1876, he went on further expedit ...

Greater Antilles
The Greater Antilles ( es, Grandes Antillas or Antillas Mayores; french: Grandes Antilles; ht, Gwo Zantiy; jam, Grieta hAntiliiz) is a grouping of the larger islands in the Caribbean Sea, including Cuba, Hispaniola, Puerto Rico, Jamaica, and the Cayman Islands. Six island states share the region of the Greater Antilles, with Haiti and the Dominican Republic sharing the island of Hispaniola. Together with the Lesser Antilles, they make up the Antilles. While most of the Greater Antilles consists of independent countries, Puerto Rico is an unincorporated territory of the United States, while the Cayman Islands are a British Overseas Territory. The largest island by area is Cuba, which extends to the western end of the island group. Puerto Rico lies on the eastern end, and the island of Hispaniola, the largest island by population, is located in the middle. Jamaica lies to the south of Cuba, while the Cayman Islands are located to the west. The state of Florida is the closes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Ginglymostoma Cirratum
The nurse shark (''Ginglymostoma cirratum'') is an elasmobranch fish in the family Ginglymostomatidae. The conservation status of the nurse shark is globally assessed as Vulnerable in the IUCN List of Threatened Species. They are considered to be a species of least concern in the United States and in The Bahamas, but considered to be near threatened in the western Atlantic Ocean because of their vulnerable status in South America and reported threats throughout many areas of Central America and the Caribbean. They are directly targeted in some fisheries and considered by-catch in others. Nurse sharks are an important species for shark research. They are robust and able to tolerate capture, handling, and tagging extremely well. As inoffensive as nurse sharks may appear, they are ranked fourth in documented shark bites on humans, likely due to incautious behavior by divers on account of the nurse shark's calm, sedentary nature. Taxonomy The nurse shark genus ''Ginglymostoma'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Indian Manatee
The West Indian manatee (''Trichechus manatus''), also known as the North American manatee, is a large, aquatic mammal native to warm coastal areas of the Caribbean, from the eastern US to northern Brazil. Living alone or in herds, it feeds on underwater plants and uses its whiskers to navigate. It is divided into two endangered subspecies, the Florida manatee (''T. m. latirostris'') in the US and the Antillean manatee (''T. m. manatus'') in the Caribbean, both of which face pressure from habitat loss, pollution, and other human activity. The West Indian manatee is the largest of the sirenians (order Sirenia), a group of large aquatic mammals that includes the dugong, other manatees, and the extinct Steller's sea cow. Manatees are herbivores, have developed vocal communication abilities, and are covered in highly sensitive whiskers (called vibrissae) that are used for feeding and navigation. In breeding season, several males form mating herds around an individual female; on aver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caulerpa
''Caulerpa'' is a genus of seaweeds in the family Caulerpaceae (among the green algae). They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world. A species in the Mediterranean can have a stolon more than long, with up to 200 fronds. This species can be invasive from time to time. Referring to the crawling habit of its thallus, the name means 'stem (that) creeps', from the Ancient Greek ' (, ‘stalk’) and ' (, ‘to creep’). Taxonomy and nomenclature First described by Jean Vincent Lamouroux in 1809, ''Caulerpa'' is the only genus under the family Caulerpaceae, from the order Bryopsidales, class Ulvophyceae, and phylum Chlorophyta. Through the use of ''tuf''A gene sequencing, it was revealed that ''Pseudochlorodesmis'' F. Børgesen was a sister clade of ''Caulerpa''. Cremen et al. proposed a new classification scheme in Bryopsidales, wherein Caulerpaceae and Halimedaceae were described as sister fami ...

Halodule Wrightii
''Halodule wrightii'' is an aquatic plant in the Cymodoceaceae family. It is referred to by the common names shoal grass or shoalweed, and is a plant species native to seacoasts of some of the warmer oceans of the world. ''H. wrightii'' is an herb growing in salt-water marshes in intertidal regions, often submerged at high tide but emergent at low tide.Godfrey, R. K. & J. W. Wooten. 1979. Aquatic and Wetland Plants of Southeastern United States Monocotyledons 1–712. The University of Georgia Press, Athens. Taxonomy This plant was named after Charles Wright, who was an American botanist and collector. In 1853 and 1856 Wright participated in a surveying expedition and discovered ''Halodule wrightii''. Some publications cite US specimens by the synonym, ''Halodule beaudettei'', but the two names represent the same species.

Halophila Decipiens
''Halophila decipiens'', commonly known as Caribbean seagrass or paddle grass, is a seagrass in the family Hydrocharitaceae. It grows underwater on sandy or muddy sea floors in shallow parts of tropical seas. Description ''Halophila'' is the only genus of seagrass that lacks basal sheaths on the leaf stems. ''Halophila decipiens'' has thin rhizomes that run along near the surface of sand or mud, with a root at each node to anchor the plant in place. The almost stemless leaves grow in pairs from the nodes with a pair of scales at their base. The leaves are paddle-shaped and have a finely serrated margin and are up to long and wide. Male and female flowers are found on the same spathe and a female flower can produce about 30 seeds. Flowering seems to be stimulated by a rise in water temperature above a certain threshold rather than day length. The plant is an annual.

Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...
