Aplacophora The affinities of Aplacophorans have long been uncertain. Molecular and fossil evidence seemed to put Aplacophorans in the clade Aculifera, as a sister group to Polyplacophora. The discovery of "Kulindroplax" in 2012, a fossil aplacophoran with a polyplacophoran-like armour, strongly supports this hypothesis, and shows that aplacophorans evolved from progenitors that bore valves.
Aplacophora Aplacophorans are cylindrical and worm-like in form, and most very small, being no longer than ; some species, however, can reach a length of .
Kulindroplax While other fossil taxa like "Acaenoplax" and "Phthipodochiton" showed intermediate features between aplacophorans and polyplacophorans, no unambiguous fossil with an aplacophoran-like body and a polyplacophoran-like shell has been found before "Kulindroplax".
Heloplax It is very bizarre by modern standards; it bears serially repeated units, and has spines. It probably falls somewhere between the aplacophorans and polyplacophora; its valves were composed of aragonite
Kulindroplax "Kulindroplax" seems adapted to moving through a substrate, with the spicules acting as "sediment ratchets". In contrast with some modern aplacophorans like the caudofoveates, which live within the sea bottom sediments, "Kulindroplax" probably crawled on the bottom, requiring a dorsal armour.
Chiton Chitons were first studied by Carl Linnaeus in 1758. Since his description of the first four species, chitons have been variously classified. They were called Cyclobranchians ("round arm") in the early 19th century, and then grouped with the aplacophorans in the subphylum Amphineura in 1876. The class Polyplacophora was named by de Blainville 1816.
Kulindroplax Kulindroplax perissokomos is a Silurian mollusk, known from a single fossil from the Wenlock Series "Lagerstätte" fauna of England. It lived during the Homerian Age (about 425 million years ago). It is considered a basal aplacophoran. Unlike all modern aplacophorans, which are shell-less, "Kulindroplax" has a chiton-like shell, and it is considered a transitional fossil in the evolution of molluscs.
Aplacophora The relationship with other molluscs, however, is apparent from some features of the digestive system; aplacophorans possess both a radula and a style. A variety of radular forms and functions exist. Solenogasters are hermaphroditic, but caudofoveates have two sexes, and reproduce by external fertilization. During development, the mantle cavity of the larva curls up and closes, creating the worm-like form of the adult.
Christoffer Schander According to his web page, he considered the goal of his research to be understanding the roles that evolutionary forces and phylogeny have played in creating organismal diversity. To help develop this understanding, he used phylogenetic analyses that integrated morphological, ultrastructural and molecular data. His research focused on molluscs and more specifically on the ectoparasitic pyramidellid gastropods and the, shell-less, primary deep-sea aplacophorans, the biogeography of these animals, and the relationship between the molluscs and other animal groups.
Kulindroplax "Kulindroplax" is about wide and long. It is the first known mollusk showing an unambiguous combination of valves, or exterior shells, and a worm-like body. It bears seven similar, unarticulated valves, with a shorter head valve and a taller caudal one, lacking ornaments and also several densely packed, long spicules. It has no discernible foot, and the radula is not preserved. A gill array is present, along with a respiratory cavity opening posteriorly. These features make it more reminiscent of caudofoveate aplacophorans.
