One-way processing of nutrients; specialization of the digestive tract.
: Radial ( Cnidarians ) vs. Bilateral (most "higher" invertebrates).
Parasitic flukes (e.g., Schistosoma ) possessing specialized ventral and oral suckers to anchor within hosts. They feature complex life cycles involving multiple intermediate hosts. invertebrate zoology lecture notes ppt new
Animals develop from two primary embryonic germ layers: an outer ectoderm and an inner endoderm (e.g., Cnidaria).
Hexapoda : Insects. Three-part body plan (head, thorax, abdomen), three pairs of walking legs attached to the thorax, and frequently one or two pairs of wings. They undergo either incomplete transformation ( development) or complete transformation ( holometabolous development with a distinct pupal stage). Module 5: Deuterostome Invertebrates Parasitic flukes (e
: The concentration of nervous tissues and sensory organs at the anterior (head) end, driven by bilateral symmetry.
Arthropods are the largest phylum in the animal kingdom. Their evolutionary success stems from unique adaptations. Hexapoda : Insects
