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. ???

The Magnuson- Stevens Act Tessa and Mallory Actually the Magnuson-Stevens Fishery Conservation and Management Act Sets up eight Regional Fishery Management Councils that work to manage their regions? fisheries. Enacted in 1976 when the issue of foreign fishers depleting US fish supplies came to surface Mostly known for the regulation saying that only US fishing boats could fish within 200 miles of our shore Annual Catch Limits (known as ACLs) were put up to ensure that fish supplies were not depleted too much, or beyond repair, in a single year. The ACL also limited sale, catch and transport of some specific fishes. Acceptable Biological Catches (ABCs) are very similar to ACLs; they regulate fish catch amounts. The MSA also regulated fishing equipment/technology, and vessel permits.

Sharks are a group of fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii), and are the sister group to the rays. However, the term "shark" has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus. Under this broader definition, the earliest known sharks date from more than 420 million years ago.[1]

Chapter 34 Vertebrates Lecture Outline Overview: Half a Billion Years of Backbones Vertebrates are named for vertebrae, the series of bones that make up the vertebral column or backbone. There are about 52,000 species of vertebrates, far fewer than the 1 million insect species on Earth. Plant-eating dinosaurs, at 40,000 kg, were the heaviest animals to walk on land. The biggest animal that ever existed is the blue whale, at 100,000 kg. Humans and our closest relatives are vertebrates. This group includes other mammals, birds, lizards, snakes, turtles, amphibians, and the various classes of fishes. Concept 34.1 Chordates have a notochord and a dorsal, hollow nerve cord The vertebrates belong to one of the two major phyla in the Deuterostomia, the chordates.
