Especialização predatória de escorpiões marinhos (Eurypterida-Pterygotoidea) 🦂🦀

Eurypterids, known as “sea scorpions,” were extinct aquatic arthropods that played an important role in Paleozoic ecosystems. With anatomical features adapted for predation, such as spiny appendages and stereoscopic vision, eurypterids would have been efficient predators. Evidence for this comes from crush marks on the fossil of a jawless fish known as Lecrhiaspis Patula, which suggested that the most likely predator was the pterygotid eurypterid Jaekelopterus howelli. This suggests direct evidence of predator-prey interactions for eurypterids and agnathans. These data reinforce the ecological role of eurypterids in prehistoric seas. In this video, we will learn more about the biology of eurypterids as well as explore predatory interactions between arthropods and primitive vertebrates. 🤳 For more content, follow Rastro Evolutivo on Instagram:   / rastroevolutivooficial   👨‍🔬Who is Cleiton?
