Functional anatomy of Polychaetes
- Focus: To investigate the evolutionary relationships between different families of polychaetes by studying their functional anatomy using micro-CT scanning
We are developing methods to improve the study of functional anatomy in polychaetes, using non-damaging reversible staining and micro-CT.
We are assessing and describing the internal anatomy of the pharynx of polychaetes and relating these findings to the evolutionary relationships between different families.
The pharynx of polychaete worms is a complex arrangement of nerves and muscles. These features are compared when studying evolutionary relationships between polychaete families.
X-ray micro-CT scanning technology
The pharynges of polychaetes can be imaged in great detail in less time than dissection and with no destruction of the specimen.
CT scanning provides virtual dissections that can be viewed along any plane or combined to form a 3D model of the specimen.
A representative species of most families within the orders Phyllodocida and Eunicida has been scanned.
