Frogs cross the Egnatia highway in northern Greece, on Thursday. For a second day, near the town of Langadas, millions of frogs migrated from a nearby lake probably looking for food. Greek officials say the colony of frogs forced the closure of a key northern highway for two hours after three drivers skidded off the road while trying to dodge the frogs. No human injuries were reported.
