the organization for this topic i find confusing. seems like killer whale dwarfism is different than the differences in the ecotypes, in particualr the differences between ecotype B and C and the others. I could be wrong. Seems like I would have the articles be about the different exoctypes and spend the content explaining the range, feeding,genetics and behavior of each ecotype. or if you focusing on dwarfism in whales make that more clear and the connection between that and the different ecotypes.
