e) Coelenterates and Sponges 



Carotenoids in coelenterates and sponges have been repeatedly studied in 

 recent years, especially by Lonnberg. In contrast to Krukenberg, and 

 MacMunn, this author did not observe any single-banded red carotenoids 

 and describes only the presence of pigments of the carotene and xanthophyll 

 type. Most studies in this field are again confined to spectroscopic observations, 

 so that the data are not conclusive.
