- Annelids use the R strategy due to their large and rapidly increasing population.
- These worms are born as young adults already and therefore do not need to stick around their mommy to grow up safely.
- Annelids are also able to divid themselves in half making for an even more rapidly growing population.
- While some reproduce asexually and others only mate once, a majority of annelids reproduce multiple times throughout their lives; this is another practice of the R strategy.
