(plural camptotrichia))
rays which support the fin membranes in Dipnoi and Crossopterygii. Actinotrichia are not found distal to the camptotrichia in the fin membrane. This suggests that they are homologous to the ceratotrichia of Elasmobranchii but for the fact that they are segmented, branched and more or less ossified like lepidotrichia. They are covered with scales. It is not clear whether they are segmented and branched actinotrichia or lepidotrichia which have lost their terminal actinotrichia
