How do animals navigate over long distances?
Category: Biology
Status: Queued
Migratory birds, sea turtles, monarchs and salmon all navigate with high precision over thousands of kilometres. Cryptochrome-based magnetoreception, sun and star compasses, and olfactory maps all play roles.
The molecular and circuit-level basis of magnetic-field sensing in particular is one of the most puzzling sensory mechanisms in biology.
