what animal eats upside down

Flamingos are the animals that eat upside down. They are known for their habit of eating with their head upside-down, which is largely due to the structure of their mouth and the logistics of lowering their long, graceful neck into the water. This behavior allows flamingos to feed effectively in their natural habitat, but it has ramifications in other aspects of their lives. Flamingos are filter feeders and they feed by sucking water and mud in at the front of the bill and then pumping it out again at the sides. Here, briny plates called lamellae act like tiny filters, trapping shrimp and other small water creatures for the flamingo to eat. Sometimes they swim to get their food and sometimes by “upending” (tail feathers in the air, head underwater) like ducks.
