Extractions: Unit 7: Invertebrates Overview: Almost all of the animals on earth are invertebrates from sponges to insects, they populate the planet in amazing numbers and diversity. Starting with the simple invertebrates like corals and anemones and moving on through the worms and insects, we study the relationship between anatomy and environment. The two dissections in this unit (earthworm and grasshopper) bring us "up close and personal" with the inner workings and adaptations of invertebrates.

Extractions: Marine Science Activities Field Studies Voyages Tropical Marine Biology Curriculum Course Description: The biological and the physical processes interacting with tropical marine organisms including coral reefs, mangroves, and birds, will be introduced and discussed in detail. Particular emphasis will be placed on the integration of ecological processes with the biodiversity and richness of tropical habitats. An introduction to the biology and identification of tropical coral reef organisms will prepare students for underwater research activities to study the ecological processes involved in maintaining high species diversity. A series of evening presentations, discussions and debates will address reef management issues and students will conduct projects to explore areas of interest in more detail. This is a field-oriented course designed to introduce students to the techniques used in the study of biology, ecology, and physiology of subtidal organisms. Current underwater research methods are learned and implemented in underwater exercises. The course is taught and supervised by educators with degrees in the marine science.

The Invertebrate Animals sponges (Phylum Porifera). sponges are sessile, spending their livesanchored to a solid surface underwater; cnidarians (Phylum Cnidaria). http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/I/Invertebrates.html
Extractions: The Invertebrate Animals Index to this page Sponges are sessile, spending their lives anchored to a solid surface underwater most are marine although some live in fresh water diploblastic ; that is, the body wall is made of two layers of cells with a jellylike mesoglea between them the body wall is perforated with pores (hence the name Porifera) through which water containing food particles is filtered dispersed by small, free-swimming larvae

Extractions: Porifera Cnidarians Platyhelminthes Mollusks ... General Resources Introduction~~ Somewhere around 9 or 10 million species of animals share the earth with us! We do not know the exact number, and even our estimate are very rough. Animals range in size from no more than a few cells to organisms weighing many tons, such as blue whales and giant squid. Most animals live in the oceans, with fewer in fresh water and even fewer on land. You have been looking at the diversity, complexity, and characteristics of an organism in the invertebrate phyla. Now you will use some sites on the Internet to add to your knowledge of invertebrates. Living things are classified in a hierarchical taxonomy. The basic levels of this hierarchy are: Kingdom

Extractions: This large species attains 80 mm or more in length and 10 to 12 mm in width. The entire body of the worm is buff colored with flecks of purple pigment. These worms inhabit tough, leathery tubes covered with fine mud. Radioles (branched tentacles) lack stylodes (small finger-like projections on the tentacles of some sabellids) and eyespots and are patterned with dark brown and buff bands. There is a pair of long, slender palps and a 4-lobed collar. These worms are very conspicuous on reef flats and harbor structures because of their large size and banded pattern of the branchial crowns (from Bailey-Brock 1987). Abundant on Oahu's south shore reefs, and in Pearl Harbor and Kaneohe Bay at shallow depths, especially in dredged areas that receive silt-laden waters. Also found in pockets and crevices in the reef flat. It is especially abundant along the edges of reefs that have been dredged, as at Ala Moana and Fort Kamehameha, Oahu; it may be an indicator of waters with high sediment content (Bailey-Brock 1976). Reported from a wide variety of coastal habitats (e.g., in holes, crevices, and matted algae at outer reef edges of rocky shores, from interstices of the coral Pocillopora meandrina; from under boulders in quiet water, in crevices in lava, in open coast tide pools, and from tidal channels exposed to heavy surf).
Extractions: Labeling is an important step in collecting any specimen. Labels should include the collectors name, date, exact location, habitat type (e.g., wooden pier piling, floating dock, patch reef, etc.), and depth of collection. Detailed notes regarding the living color of the animal are essential for the positive identification of many invertebrate groups, as most animals lose all color upon preservation. Photographing the living specimen before preservation is ideal. Labels should be placed inside collection bags or bottles as soon as possible, preferably at the time of collection. Specimens should be placed on ice in the field or quickly transported in sea water to a laboratory for sorting and preservation. In most cases, specimens should be narcotized and preserved within eight hours. Preservation Methods for Specific Taxa Sponges
Extractions: INDEX Mollusca Cowrie Shell Giant Tun Shell ... Worms INTRODUCTION L ook into any of the tour company holiday brochures featuring the coastal resorts of Turkey and you will think that the clear vivid turquoise waters shown in the photographs are less than real. It is not until you have your first glimpse of the sea as you approach your resort that you appreciate that the colours are realistic. The waters of the Central and Southern Aegean Coast and the Turquoise Coast are relatively low in Phyphotoplankton, the first link in the marine food chain, and the reason for the exceptional clarity of the water. It is a mystery as to why the water is such a brilliant turquoise colour along this part of the Turkish coast.
