C All work in the same basic way: Body fluid is filtered by a special organ. Selectively permeable membranes remove urea or uric acid. Osmolarity is controlled by selective reabsorption/secretion. C 5 types of excretory systems: None in porifera‚ cnidaria Protonephridia in planaria & rotifers Metanephridia in annelids Malpighian tubules in terrestrial arthropods Kidneys (with nephrons) in vertebrates Protonephridia Have flame bulbs‚ tubules‚ and nephridopores.

The classification of animals The Classification of animals : Animal Kingdom can be split up into main groups‚ vertebrates (with a backbone) and invertebrates (without a backbone). When you think of an animal‚ you usually think of something like a cat‚ a dog‚ a mouse‚ or a tiger. All told‚ around 800‚000 species have been identified in the Animal Kingdom -- most of them in the Arthropod phylum. In fact‚ some scientists believe that if we were to identify all species in the tropical rain forests

Animal Kingdom The animal kingdom is a taxonomic kingdom composed of multicellular‚ eukaryotic organisms. Mostly‚ their body structures become fixed as they develop‚ yet still some organisms in this kingdom have the ability to undergo metamorphosis. The majority of these organisms are motile‚ which means they can move on their own and with spontaneity. All animals are heterotrophic‚ which implies that they depend on other organisms for food. Animals live in places that provide their necessities

the past jellyfish could only be viewed in the ocean or in public aquariums; however people are now able to keep them as pets. The oldest know record of a jellyfish dates back 505 million years. Jellyfish Structure Jellyfish are members of the cnidaria or stinging animals. Jellyfish are symmetric resembling a flower. The structure is very simple; it consists of a bag of cells in both the inside and the outside and a mouth in the middle. Most of the jellyfish family consists of two life cycles‚

endoderm and ectoderm. It forms the muscles and most other organs towards the upper layer of the animal. Diploblastic animals‚ or animals with only two germ layers‚ lack mesoderm. There are only two diploblastic phyla: Porifera‚ the sponges‚ and Cnidaria‚ the "bag animals." All other animals are triploblastic. In fact‚ sponges are such simple animals that they lack even true tissue. They are in the parazoan category (parazoans lack true tissue). Sponges are the only animals that are parazoans- all

Chrysaora fuscescens is the scientific name of the Pacific sea nettle. They belongs to phylum Cnidaria. They are native to the San Francisco Bay‚ and‚ as the name suggests‚ these jellyfish live in the Pacific Ocean. They thrive along the coasts of Oregon and California. They can also be found farther north in Japan and Alaska‚ although they are not as common in these northern waters. On occasions‚ they have been spotted as far south as the west coast of Mexico. During autumn and winter‚ Pacific sea
