Were any of the features used in more than one Phyla? If;so, give an example of an organism from each phyla that shares the feature.;2. List three features from Table 1 that describe a Monarch;butterfly (Danaus plexippus)? Using the features you listed, determine;what phyla it is classified in.**********************************************llali) ? Invertebrates and Vertebrates??

Table 1 contains all of the main features of the eight major phyla discussed in theIntroduction. Organize and identify which characteristics belong to which phyla in the key. Thenumber of rows in the key repre- sents the number of characteristics that fall into each phylum.2.
