New approaches narrow global species estimates for beetles . . . Using analogous approaches, we also produce independent estimates for all insects, mean: 5 5 million species (range 2 6–7 8 million), and for terrestrial arthropods, mean: 6 8 million species (range 5 9–7 8 million), which suggest that estimates for the world’s insects and their relatives are narrowing considerably
Batodonoides | Size Facts | Britannica Batodonoides, genus of extinct insectivorous mammals that lived during the Eocene Epoch (56 to 33 9 million years ago) and of which the oldest species, Batodonoides vanhouteni, may have been the smallest mammal that ever lived The genus includes three other species as well—B walshi, B powayensis, and B rileyi

The Cellular Composition and Glia-Neuron Ratio in the Spinal . . . In the cynomolgus monkey spinal cord, the isotropic fractionator and stereology yielded 206-275 million cells, of which 13 3-25 1% were neurons (28-69 million) Stereological estimates yielded 21 1% endothelial cells and 65 5% glial cells (glia-neuron ratio of 4 9-5 6)
