Toxisarcon taimyr sp. nov., a new large monothalamous foraminifer from the Kara Sea inner shelf
A large monothalamous foraminiferan, Toxisarcon taimyr sp. nov., has been isolated from the benthic samples from the Kara Sea inner shelf near the mouth of Yenisey river estuary, at a depth of 50–100 m.

Summary: | A large monothalamous foraminiferan, Toxisarcon taimyr sp. nov., has been isolated from the benthic samples from the Kara Sea inner shelf near the mouth of Yenisey river estuary, at a depth of 50–100 m. In its overall morphology, the new species closely resembles T. synsuicidica, one of the two species of Toxisarcon described to date. It possesses a large irregularly shaped cell body, covered by a thin layer of a fibrous organic coating. Numerous reticulopodia typically extend from all over the cell surface; the species is very motile and rapidly changes cell shape. Long and thick reticulopodial bundles form in the direction of movement. In the phylogenetic tree based on partial small-subunit ribosomal DNA (SSU rDNA) sequences, T. taimyr branches together with the two other known species of Toxisarcon within the clade C of monothalamous foraminifera. |
