What was the estimated length range of the Cambrian organism Wiwaxia?
Answer
Between 5 and 10 centimeters
Wiwaxia was a relatively small creature in the context of the early oceans, with scientific estimates suggesting its length spanned from a minimum of 5 centimeters up to a maximum of 10 centimeters. If considering the median estimate of approximately 7.5 centimeters, this places its size in a range comparable to modern organisms such as a large earthworm or a small freshwater shrimp. This moderate size indicates that the complex Cambrian seafloor ecosystem supported a variety of life stages and body plans living simultaneously alongside much larger forms like Anomalocaris.
