4 Animals That Don’t Have Resident Gut Microbiomes

The video explores the role of microbiomes in various animals, highlighting how bats, caterpillars, ants, and stick insects have unique relationships with gut microbes. Bats and birds have fast digestion due to flight, reducing reliance on microbes. Caterpillars have basic stomachs that deter microbes, while ants show diverse microbial partnerships. Stick insects have adapted genetically to digest plant material without microbial help. The video emphasizes caution in assuming microbial presence, as future technology may reveal more about these relationships.
