What are vertebrates and what are some examples of vertebrates?
Choose the correct answer:
- Fish
- Sea Cucumbers
- Amphibians
- Sea Stars
Answer:
Vertebrates are organisms that have a backbone, specifically a vertebral column. Some examples of vertebrates include fish, amphibians, and sea stars.
Vertebrates are a group of animals characterized by having a backbone, which consists of a series of separate bones that protect the spinal cord. This feature provides support and structure for the body, allowing for movement and coordination.
Fish are aquatic vertebrates that have gills for breathing and fins for swimming. Amphibians are vertebrates that undergo metamorphosis between an aquatic larval stage and a terrestrial adult stage. Sea stars, although they do not have a backbone, are still classified as echinoderms and not vertebrates.
It's important to understand the distinction between vertebrates and invertebrates, as the presence or absence of a backbone can have significant implications for an organism's biology and behavior.
