These Animals Lost Their Stomachs. Why?

The video explores the evolution of stomachs in animals, highlighting that some species, like pufferfish and platypuses, have evolved to live without them. Stomachs are crucial for digesting proteins, absorbing nutrients, and preventing pathogens. However, some species have developed agastric guts, possibly due to energy savings or dietary changes. These species have adapted in various ways, such as continuous feeding or enhanced digestion outside the stomach. Despite the mystery surrounding their evolution, these animals thrive without stomachs.
