Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Clingfish
Clingfishes are ray-finned fishes of the family Gobiesocidae, the only family in the suborder Gobiesocoidei of the order Blenniiformes. These fairly small to very small fishes are widespread in tropical and temperate regions, mostly near the coast, but a few species live in deeper seas or fresh water. Most species shelter in shallow reefs or seagrass beds, clinging to rocks, algae and seagrass leaves with their sucking disc, a structure on their chest. They are generally too small to be of interest to fisheries, although the relatively large ''Sicyases sanguineus'' regularly is caught as a food fish, and some of the other species occasionally appear in the marine aquarium trade. Distribution and habitat Clingfishes are primarily found near the shore in the Atlantic, Indian and Pacific Oceans, including marginal seas such as the Mediterranean, Gulf of Mexico, Caribbean Sea, Caribbean and Gulf of California. The greatest species richness is in tropical and warm temperate region ...

Opeatogenys Gracilis
''Opeatogenys gracilis'' is a species of clingfish from the family Gobiesocidae which is found in the Mediterranean Sea and in the eastern Atlantic Ocean. Suggested common names for this species are the ''pygmy clingfish'' and the ''seagrass clingfish''. Description ''Opeatogenys gracilis'' has a short snout which is depressed and triangular in shape. Its general shape is rather similar to that of the two-spotted clingfish (''Diplecogaster bimaculata''). The dorsal and anal fins are relatively small and situated close to the caudal fin. The pectoral fins are modified to form the suction disc, a characteristic of clingfishes. The colour can be greenish or orange with light blue spots and there is a white line along the back. The maximum total length is . Distribution ''Opeatogenys gracilis'' occurs only in the northeastern Atlantic Ocean from the coasts of the Algarve eastwards to the Levant. Until specimens were collected off southern Portugal, it had been considered to be endem ...

Giovanni Canestrini
Giovanni Canestrini (26 December 1835 – 14 February 1900) was an Italian naturalist and biologist and translator who was a native of Revò. Career He initially studied in Gorizia and Meran, then furthered his education in natural sciences at the University of Vienna. From 1862 to 1869, he was a lecturer at the University of Modena, and in 1869 became a professor of zoology and comparative anatomy at the University of Padua. In 1862 he founded the ''Società dei Naturalisti Modenesi'' (Modena Society of Naturalists), and in 1871, the ''Società Veneto-Trentina di Scienze Naturali'' (Trento-Venetian Society of Natural Sciences). He is credited with establishment of the bacteriology laboratory at Padua. Canestrini made contributions in several biological disciplines, performing important research in the field of acarology. He was an advocate of Darwinism, and was responsible for translating Darwin's works. In 1864, he was the first to translate Darwin's ''On the Origin of Species ...
