Padina Boergesenii
''Padina boergesenii'', commonly known as the leafy rolled-blade alga, is a species of small brown alga found in the tropical and subtropical western Atlantic Ocean, the Mediterranean Sea, and the Pacific Ocean. This seaweed was named in honour of the Danish Botany, botanist and Phycology, phycologist Frederik Børgesen. Description ''Padina boergesenii'' is a distinctive small brown alga with rounded fronds growing to a length and diameter of . Fronds are thin, leafy, and flat, with narrow or wide lobes, and grow on short stems from a fibrous, bulbous holdfast (biology), holdfast. They are moderately calcified on the underside and are usually pale brown or tan. The fronds are either two or three cells thick, but the bases are usually three cells thick. The surface of the fronds bear many short hairs, giving them a matted appearance. Distribution ''P. boergesenii'' has a wide but scattered presence in shallow water in tropical, subtropical, and warm temperate oceans. In Australi ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
