Jointed appendages - Limulus, Apis, Laccifer
In poriferans, the body is supported by a skeleton made up of spicules or spongin fibres. Sycon and Spongilla are examples of poriferans, whereas Adamsia is a coelenterate.
In platyhelminths, specialised cells called flame cells help in excretion. Taenia and Fasciola are platyhelminths whereas Ancylostoma is an aschelminth.
In molluscs, mouth contains a file-like rasping organ for feeding called radula. Dentalium and Octopus are molluscs whereas Ophiura is an echinoderm.
Arthropods have jointed appendages. Limulus, Apis and Laccifer all three are arthropods
