1 Acknowledgement: Nearly all materials in these three Animal Diversity labs are adapted from Seattle Community College Bio 212 online lab material. Animal Diversity Three IX Phylum Echinodermata The approximately 7,000 species of echinoderms are spiny skinned, slow moving or sessile marine animals that are voracious feeders. Adults have an unusual symmetry not found in any other animal. They have a pentamerous radial symmetry, meaning that the body is arranged into five (or multiples of five) repeating units radiating from a central area. However, their larval stages have bilateral symmetry which changes to pentamerous during development. Embryological development follows the typical deuterostome pattern.

Campbell's Biology, 9e (Reece et al.) Chapter 34 The Origin and Evolution of Vertebrates A little more than 40% of the questions in Chapter 34 are scenario- or art-based or a combination thereof. There are two new sets of scenario questions, one pertaining to the air sacs of birds and the other to a devastating disease of bats in the eastern United States and Canada, thought to be caused by a fungus new to science. The new set of art questions pertains to swim bladders. Multiple-Choice Questions 1) Chordate pharyngeal slits appear to have functioned first as A) the digestive system's opening. B) suspension-feeding devices. C) components of the jaw. D) gill slits for respiration. E) portions of the inner ear. Answer: B Topic: Concept 34.1

Invertebrates sponges, segmented worms, echinoderms, mollusks, and arthropods They do not have backbones or internal skeletons.? Some have external skeletons, called exoskeletons ??? Sponges -Very simple animals that have many pores (holes) through which water flows. -Water moves into a central cavity and out through a hole in the top. -obtain their food and eliminate wastes through this passage of water. -They have specialized cells for obtaining food and oxygen from the water. ??? Cnidarians -Hollowed-body animals with cells organized into tissues. -Have tentacles surrounding their mouth that contain stinging cells used to help capture its prey. -Have radial symmetry and two different body forms: polyp and medusa. -Examples are sea anemones, hydra, corals, and sea jellies. ???
