Chiton phylogeny has gone relatively underexplored compared to the more charismatic classes of molluscs, and as such is still somewhat poorly understood. The relationships between orders and superfamilies has been made clear thanks to phylogenomics, [ 42 ] [ 43 ] but interfamilial relationships are still largely unknown because of the lack of ...
The distribution of Chiton magnificus ranges along the Pacific coast of South America from Cape Horn in Chile [3] to San Lorenzo Island in Peru. [2] Although there are old claimed records of this species from the Galápagos Islands, these are now considered incorrect.
Still Waters is the twenty-first and penultimate studio album by the Bee Gees, released on 10 March 1997 in the UK by Polydor Records, and on 6 May the same year in the US by A&M Records.

The Calcaires du Bou Dahar (also known as Djebel Bou Dahar Paleoshoal, Djebel Bou Dahar, Calcaires du Bou Dahar Formation, or Bou Dahar Formation) is a geological formation or a sequence of formations of Late Sinemurian to Pliensbachian-Toarcian boundary (Early Jurassic) age in Bni Tadjite, the Central High Atlas, Morocco.
In contrast to many other mollusc classes, aplacophorans have no shell, and are instead covered by aragonitic sclerites (calcareous spicules), which can be solid or hollow.. These spicules can be arranged perpendicular to one another within the cuticle to form a skeleton, stick up to form a palisade, or can lie flat against the cutic
Animals out of water only have about 73% the respiration of submerged animals, and likely incur an oxygen debt while out of water that must be repaid once resubmerged. [4] When submerged, gas exchange occurs by water flowing from the anterior portion of the chiton into the mantle cavity where the ctenidia (gills) reside in the pallial grooves.
Mark Ruffalo's new film 'Dark Waters' is generating Oscar buzz as well as concern about unexpectedly toxic chemicals. ... and the effects of many unregulated chemicals still haven't been explored ...
In 2006 a molecular study on Laevipilina antarctica suggested that extant Monoplacophora and Polyplacophora form a well-supported clade with the researched Neopilina closest to the chitons. [6] The two classes in this new clade, with the proposed name Serialia, all show a variable number of serially repeated gills and eight sets of dorsoventral ...
