... Hermaphrodites are animals that produce both sperm & eggs. Ex: earthworms – crossfertilize with each other (exchange sperm) & tapeworms can self-fertilize in their body sections called proglottids Echinoderms, arthropods, mollusks, & vertebrates have separate sexes (sperm to egg) Internal fertilizat ...

Invertebrate
Invertebrates are animals that neither possess nor develop a vertebrae (vertebral column) , derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects, crabs, lobsters and their kin, snails, clams, octopuses and their kin, starfish, sea-urchins and their kin, and worms.The majority of animal species are invertebrates. One estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata.Some of the so-called invertebrates, such as the Chaetognatha, Hemichordata, Tunicata and Cephalochordata are more closely related to the vertebrates than to other invertebrates. This makes the term ""invertebrate"" almost meaningless for taxonomic purposes.
