Expression of Distal-less, dachshund, and optomotor blind in Neanthes arenaceodentata (Annelida, Nereididae) does not support homology of appendage-forming mechanisms across the Bilateria [PDF]

, 2010
The similarity in the genetic regulation of arthropod and vertebrate appendage formation has been interpreted as the product of a plesiomorphic gene network that was primitively involved in bilaterian appendage development and co-opted to build ...

Occurrence, Abundance, and Diversity of Gill Fouling Organisms in Snow Crab, Chionoecetes opilio (O. Fabricius, 1788), (Decapoda, Brachyura, and Oregoniidae) in the Northwestern Atlantic Ocean, Canada

International Journal of Zoology, Volume 2026, Issue 1, 2026.
Gill fouling organisms (GFO) in snow crab (Chionoecetes opilio) were identified and grouped into 10 taxons, representing 7 phyla. An unknown harpacticoid copepod species (Coullia sp.) was described and the presence of a kinorhyncha species (Echinoderes sp.) was first observed.

The early expansion and evolutionary dynamics of POU class genes. [PDF]

, 2014
The POU genes represent a diverse class of animal-specific transcription factors that play important roles in neurogenesis, pluripotency, and cell-type specification. Although previous attempts have been made to reconstruct the evolution of the POU class,
