Video: Life disorder phenomenon in North America
Numerous North American ticks are suffering from life cycle disorders when they crawl off the ground four years earlier than expected.
This life cycle disorder can help avoid predators.
10% of ticks in eastern North America crawl to the ground 4 years earlier than their lifespan. Instead of lying in the ground for 17 years, they crawled up to mate and maintain the race after 13 years.
Some experts believe that this life cycle disorder can help avoid predators who appear to cycle on their ground.
