After having their lower halves amputated, the majority of the spiders recovered and produced new muscles.
A new study shows that sea spiders may regenerate body components following amputation in addition to limbs., several species can regenerate lost body parts even though it's not frequent. However, scientists believed that an arthropod's ability to grow new legs was the extent of its abilities, maybe because of their hard exteriors, which prevent them from growing new body parts.
Four adults did not regenerate, according to biologist and co-author of the study Georg Brenneis. This may be the case because adults no longer molt as they grow, which suggests that regeneration and molting are somehow related. Two newbornlikewise showed no signs of regeneration. The spiders managed to survive despite having only four legs and no anus. The two regurgitated waste out of their mouths rather than passing it. The next step might be to look for the regrowth mechanism.

Global patterns of diversity and metabolism of microbial communities in deep-sea hydrothermal vent deposits - MicrobiomeBackground When deep-sea hydrothermal fluids mix with cold oxygenated fluids, minerals precipitate out of solution and form hydrothermal deposits. These actively venting deep-sea hydrothermal deposits support a rich diversity of thermophilic microorganisms which are involved in a range of carbon, sulfur, nitrogen, and hydrogen metabolisms. Global patterns of thermophilic microbial diversity in deep-sea hydrothermal ecosystems have illustrated the strong connectivity between geological processes and microbial colonization, but little is known about the genomic diversity and physiological potential of these novel taxa. Here we explore this genomic diversity in 42 metagenomes from four deep-sea hydrothermal vent fields and a deep-sea volcano collected from 2004 to 2018 and document their potential implications in biogeochemical cycles. Results Our dataset represents 3635 metagenome-assembled genomes encompassing 511 novel and recently identified genera from deep-sea hydrothermal settings. Some of the novel bacterial (107) and archaeal genera (30) that were recently reported from the deep-sea Brothers volcano were also detected at the deep-sea hydrothermal vent fields, while 99 bacterial and 54 archaeal genera were endemic to the deep-sea Brothers volcano deposits. We report some of the first examples of medium- (≥ 50% complete, ≤ 10% contaminated) to high-quality (| 90% complete, | 5% contaminated) MAGs from phyla and families never previously identified, or poorly sampled, from deep-sea hydrothermal environments. We greatly expand the novel diversity of Thermoproteia, Patescibacteria (Candidate Phyla Radiation, CPR), and Chloroflexota found at deep-sea hydrothermal vents and identify a small sampling of two potentially novel phyla, designated JALSQH01 and JALWCF01. Metabolic pathway analysis of metagenomes provides insights into the prevalent carbon, nitrogen, sulfur, and hydrogen metabolic processes across all sites and illustrates sulfur and nitrogen metabolic “hand
