TED-Ed: Is this the most successful animal ever? | Nigel Hughes

Trilobites were highly successful marine arthropods that thrived around 500 million years ago. They were among the first animals with complex eyes and played a significant role in the Cambrian explosion. Trilobites exhibited diverse physical traits and social behaviors, adapting to various ecological niches. Despite their dominance, they eventually succumbed to environmental changes and predators. Their fossils provide valuable insights into ancient marine ecosystems, and their evolutionary legacy continues through their arthropod relatives.
