Order Notostraca - English Definition & Meaning

Definition

Order Notostraca comprises the tadpole shrimp, ancient crustaceans with a distinctive shield-like carapace. These creatures inhabit temporary freshwater pools, surviving in harsh, fluctuating environments. They are considered living fossils, having changed little over millions of years. Their life cycle involves rapid growth and reproduction during the brief wet periods. They play a role in their ecosystem as benthic feeders. Notostracans are fascinating examples of evolutionary stasis. They're like time travelers from the age of dinosaurs.

Etymology

This precisely describes the prominent dorsal carapace characteristic of these crustaceans. It highlights the defining physical feature of the group. The name emphasizes the descriptive approach in taxonomy. Understanding the etymology offers a quick identification of the group's most noticeable trait.
