Did trilobites climb trees and hunt insects?
No, trilobites did not climb trees and hunt insects. Trilobites were marine arthropods that lived in the oceans for almost 270 million years, with over 22,000 species having been described. They were distant relatives of lobsters, spiders, and insects that died off more than 250 million years ago, before the dinosaurs even came into existence. Trilobites are generally found in rocks that indicate they were marine animals, and they were never known to live on land.

Trilobites were highly diversified and evolved into many ecological niches. Some moved over the seabed as predators, scavengers, or filter feeders, and some swam, feeding on plankton. Some even crawled onto land. However, crawling onto land does not necessarily mean that they climbed trees and hunted insects. Most lifestyles expected of modern marine arthropods are seen in trilobites, with the possible exception of parasitism.

Trilobites were blind, probably living too deep in the sea for light to reach them. As such, they became secondarily blind in this branch of trilobite evolution. Some trilobites had large eyes that were for use in well lit, predator-filled waters. It is highly unlikely that blind marine animals could climb trees and hunt insects.

In conclusion, trilobites did not climb trees and hunt insects. They were marine arthropods that lived in the oceans and evolved into many ecological niches. While some trilobites crawled onto land, it does not mean that they climbed trees and hunted insects.
