Document Summary
Solutions: eating plants, eat other animals, eating plants = herbivory. Every possible part of the plant can be used by animals for nutrition. Some animals have food delivered to them. Black fly larvae filter feed with elegant laberol brushes. Tongues also help filter the food from water (northern shoveler, a puddle duck) Hummingbirds have a long beak and extensible tongue. The hyoid apparatus (hyoid horns) extends the tongue. Getting plant material into the body (ingestion) Slugs and snails break off plant tissues with radula. A chainsaw like feature, moves back and forth and rips apart leaf tissue. Some caterpillars eat leaves from the inside. Leaf blotch miner (mining out the material) Incisors pull the materials in when the animal is eating (teeth) They are self sharpened and never stop growing. High iron content turns teeth orange/ yellow. Moose eat a lot of woody material. Only have bottom incisors so they rip off plant tissues.
