Pulmonate
Pulmonata or pulmonates, is an informal group (previously an order, and before that a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts.

It occupies the eastern five-eighths of the island, which it shares with Haiti, making Hispaniola one of only two Caribbean islands, along with Saint Martin, that is shared by two sovereign states. The Dominican Republic is the second-largest nation in the Antilles by area (after Cuba) at , and third-largest by population, with approximately 10.7 million people (2022 est.), down from 10.8 million in 2020, of whom approximately 3.3 million live in the metropolitan area of Santo Domingo, the capital city. The official language of the country is Spanish. The native Taíno people had inhabited Hispaniola before the arrival of Europeans, dividing it into five chiefdoms. They had constructed an advanced farming and hunting society, and were in the process of becoming an organized civilization. The Taínos also in ...

Eryngium
''Eryngium'' is a genus of flowering plants in the family Apiaceae. There are about 250 species.Wang, P., et al. (2012)Phytochemical constituents and pharmacological activities of ''Eryngium'' L. (Apiaceae). ''Pharmaceutical Crops'' 3 99-120. The genus has a cosmopolitan distribution, with the center of diversity in South America. Common names include eryngo and sea holly (though not to be confused with true hollies, of the genus ''Ilex''). These are annual and perennial herbs with hairless and usually spiny leaves. The dome-shaped umbels of steely blue or white flowers have whorls of spiny basal bracts. Some species are native to rocky and coastal areas, but the majority are grassland plants. In the language of flowers, they represent admiration. Species Species include:GRIN Species Records of ''Eryngium''. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in al ...

Reproductive System Of Gastropods
The reproductive system of gastropods (slugs and snails) varies greatly from one group to another within this very large and diverse taxonomic class of animals. Their reproductive strategies also vary greatly, see Mating of gastropods. In many marine gastropods there are separate sexes (male and female); most terrestrial gastropods however are hermaphrodites. Courtship is a part of the behaviour of mating gastropods. In some families of pulmonate land snails, one unusual feature of the reproductive system and reproductive behavior is the creation and utilization of love darts, the throwing of which has been identified as a form of sexual selection. Gastropods are defined as snails and slugs, belonging to a larger group called Molluscs. Gastropods have unique reproductive systems, varying significantly from one taxonomic group to another. They can be separated into three categories: marine, freshwater, and land. Reproducing in marine or freshwater environments makes getting s ...
