Annelid Characteristics. Annelids are to be found in marine, freshwater, and terrestrial habitats. The body is vermiform, bilaterally symmetrical, and segmented (. metamerism. ). Each segment is separated from contiguous ones by a transverse septum. Thrive in fresh water, salt water and soil.. Many are motile, with pseudopods (“false feet”) used for locomotion.. Some are parasitic species, found in animal intestines.. Entamoeba. . histolytica. Grow on fruits and breads. Saprobes and parasites. Rhizopus. : bread mould. Hyphae. Threadlike hyphae secrete enzymes which break down food. The hyphae then reabsorb the nutrients and transport them throughout the fungus by means of diffusion.. Invertebrates. Chapter 6.
