Branchiopods

Oct 17, 2023 · The longtail tadpole shrimp is the largest species of tadpole or fairy shrimp found in Montana. They can reach up to 2.5-3.5 inches (80 millimeters) in length.

Branchiopoda. Branchiopoda is a class of crustaceans. It is the sister group to the other crustaceans. They are mostly small, freshwater animals that feed on plankton and detritus. However, many of the Cladocera are marine . Branchiopods have gills on most of the animals' appendages, including some of the mouthparts. The name means "gill-foot". Our ortholog search among the 15 genomes (branchiopods+outgroups) resulted in 21,121 orthologs groups (OGs). We selected OGs containing single-copy genes for at least 10 taxa (N = 1001) to build a Maximum Likelihood phylogenetic tree.Nodal supports of the resulting tree were maximum for all nodes; Notostraca taxa formed a clearly monophyletic clade in sister relationship with Onychocaudata ...
