Which /an/s have the most interesting methods of energy/nutrient capture?Neat respiration discussion also permitted.
so apparently birds have air sacs for breathing? I feel like this ought to be common knowledge.
>>4783314I know a lot of birds eat "grit" like dirt and sand to help grind up food in their crop before they fully swallow it.
>>4783314Henneguya salminicola has no mitochondria and is incapable of aerobic respiration, meaning it does not derive energy from oxygen. It also has no mouth or gut to process nutrients. It is entirely reliant on anaerobic respiration.
rabbits eat the poo poo
>>4783457I like how gastroliths scale with animal size, where the larger dinosaurs had entire stones bouncing around in their stomachs. Apparently aquatic dinosaurs also used them as ballast.>>4783615I recently learned about the bacteria Rhodobacter capsulatus that can photosynthesize or just skip the middleman and transfer electricity directly to or from electrodes.
>>4783314>hmmmm today I will evolve 4 stomachs so I can eat as much grass as I want!!
>>4783407lungs?
>>4783647why are rabbits so lean? why are small animals so lean? sadly they make mediocre food as a result since you need an alternate fat source to eat with them. just goes to show we humans should be eating juicy megafauna and not fox bait
