Peraclidae
Peraclidae is a family of pelagic sea snails or "sea butterflies", marine gastropod mollusks in the superfamily Cymbulioidea. This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). This family was originally called Procymbuliidae Tesch, 1913 and then called Peraclididae by Wenz in 1938. The name Peraclidae takes precedence. ''Peracle'' is the type genus of the family Peraclidae. "Peraclis" Pelseener, 1888 is a unjustied modification (Giovine, F. 1988) Description The left-coiled shell resembles the shell of most snails. The columella is somewhat elongated into a curved rostrum. There is an operculum and a gill. Species Species within the genus ''Peracle'' Forbes, 1844 include: * † '' Peracle charlotteae'' Janssen & Little, 2010Janssen A. W. & Little C. T. S. (2010).

Peracle Charlotteae
''Peracle charlotteae'' is an extinct species of fossil pelagic sea snail, or "sea butterfly", a planktonic marine gastropod mollusk in the family Peraclidae. This species existed in what is now Cyprus during the Miocene The Miocene ( ) is the first epoch (geology), 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 mea ... period. It was described by Arie W. Janssen and Crispin T. S.

Thecosomata
Sea butterflies, scientific name Thecosomata (thecosomes, "case / shell-body"), are a taxonomic suborder of small pelagic swimming sea snails. They are holoplanktonic opisthobranch gastropod mollusks. Most Thecosomata have some form of calcified shell, although it is often very light and / or transparent. The sea butterflies include some of the world's most abundant gastropod species, and because of their large numbers are an essential part of the food chain, and a significant contributor to the oceanic carbon cycle. The sea butterflies are included in the Pteropoda order, and are also included in the informal group Opisthobranchia. Morphology Sea butterflies float and swim freely in the water, and are carried along with the currents. This has led to a number of adaptations in their bodies. The shell and the gill have disappeared in several families. Their gastropodal foot has taken the form of two wing-like lobes, or ''parapodia'', which propel the animal through the sea by ...

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Cymbulioidea
Cymbulioidea is a taxonomic superfamily of pelagic "sea butterflies", one group of swimming sea snails. They are holoplanktonic opisthobranch gastropod molluscs in the clade Thecosomata. Anatomy Some groups within this superfamily possess a shell in the adult stage, some are without a shell in the adult stage, and others have developed a relatively tough gelatinous, cartilaginous internal structure, a sort of fake shell called the pseudoconch. The lateral and posterior foot lobes are joined as a ciliated proboscis that leads to the mouth, and the wings are united ventrally to form a single plate. A more general description is given under the entry sea butterfly. Taxonomy The group was originally referred to as the Pseudothecosomata Meisenheimer, 1905, although this name is invalid under the ICZN and thus is no longer recognized. Instead its three families are categorized within the superfamily Cymbulioidea, which is itself part of the clade Thecosomata. The superfa ...

Paul Pelseneer
Jean Paul Louis Pelseneer (Brussels, 26 June 1863 – Brussels, 5 May 1945)Adam W. (1946). "Paul Pelseneer 1863–1945". ''Proceedings of the Malacological Society of London'' 26(6): 149-151PDF was a Belgian malacologist, morphologist, ethologist and phylogenist. In 1880, at the age of seventeen, Pelseneer became a member of the Belgian Malacological Society. He studied at the University of Brussels and in 1884 he obtained his doctor's degree in natural sciences. He continued his studies with the French zoologist Alfred Mathieu Giard at the marine laboratory in Wimereux (Université Lille Nord de France), and concluded his studies with the English invertebrate zoologist Ray Lankester at University College London. Pelseneer then became a teacher of chemistry at the Normal School in Ghent. He devoted himself to zoology during his spare time, without having a laboratory at his disposal. Pelseneer became recognized in Belgium as well as abroad as one of the most eminent zoologists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
