Studies that combine genomic and gene expression data in invertebrates would allow generalizing this observation across all animals, but are scarce, particularly within Lophotrochozoa (e.g., snails and segmented worms). Here, we use two brachiopod species – Terebratalia transversa , Novocrania ...
6 Other eukaryotes, however, express unique tubulin isotypes for specific functions, including meiotic spindle assembly in Drosophila oocytes,7 axoneme formation in diverse systems,8 and touch receptor neurons in worms.9 These specialized tubulins support the “multi-tubulin hypothesis” that posits ...
Some species eat other, smaller creatures, like microscopic worms and tiny, wheel-shaped animals called rotifers. What makes them special: They curl up into dried-up balls that can survive boiling water, freezing cold and outer space. This is called a tun state. How big they get: They ...
