Some scavenge, feeding on almost any dead or- ganic material they encounter. The gill slits are committed largely to feeding in cephalochordates and have little to do with gas exchange. Mating is usually by mutual cross-fertilization. Myxobolus cerebralis, a parasite of freshwater fishes (especially trout), devours the host’s cartilage, leaving the fish deformed. Assuming (1) to be the origin of the triploblastic, spiralian condition leading to ancestor (a), then the flatworms retain this ancestral condition and are not distinguished by any unique synapomorphies.

Animals can be classified into two main groups: vertebrates and invertebrates. The main difference between vertebrates and invertebrates is that invertebrates, like insects and flatworms, do not have a backbone or a spinal column.

Binary fission involves a single mitotic division, resulting in two daughter cells. During multiple fission, the nucleus undergoes several multiple divisions prior to cytokinesis (partitioning of the cyto- plasm), resulting in many daughter cells. This is com- mon in parasitic protists such as the Apicomplexa. Some engage in a process called plasmotomy, considered by some to be a form of budding, in which a multinucleate adult simply divides into two multinucleate daughter cells

Nervous System and Sense Organs Although the nervous systems of both ctenophores and cnidarians are noncentralized nerve nets, there are cer- tain important differences. In a ctenophore, nonpolar neurons form a diffuse subepidermal plexus. Beneath the comb rows, the neurons form elongate plexes or meshes such that they produce nervelike strands
