Sulawesi Sea Slugs Updated 24 July 2010 Updated Sea Slugs with additional species Aplysia parvula, Chelidonura hirundinina, Cyerce elegans, Dolabrifera dolabrifera and Godiva sp. along with updating to taxonomy for Aegires gardineri, Aegires minor, Asteronotus hepaticus, Nembrotha purpureolineata, Phyllidia Picta and Risbecia apolegma The island of Sulawesi in the Indonesian archipelago lies in the middle of the area of the highest marine bio-diversity in the world. The N E Sulawesi peninsula includes the Bunaken National Park, Banka Island and Lembeh Strait. We visited the area in June 2001, 2002 and July 2006 and stayed at the Hotel Santika , diving with the wonderful Thalassa Dive Centre whose great guides led us to wonderful creatures on the reefs and dark volcanic sands during our many expeditions. In March 2007 we visited Raja Ampat, north west of Papua New Guinea on board the MV Odyssea 1 This fascinating journey took us to another magical area, introduced us to new diving friends and provided many more images. Select from the links below to see more the creatures we found and photographed.

FRESHWATER MUSSEL (UNIONOIDA) GENERA OF THE WORLD Kevin S. Cummings Illinois Natural History Survey Center For Biodiversity Mollusks 607 East Peabody Dr. Champaign, IL 61820 ksc@mail.inhs.uiuc.edu The objective of this page is to illustrate (with photographs) all of the "genera" of freshwater mussels (Unionoida) in the world. The genera included are largely those recognized by Haas (1969) with the exception of the North American fauna, which follow Turgeon, et al. (1998). Other deviations from Haas (1969) will be referenced to the new source of information. If anyone spots any errors or misspellings of type localities, type designations, rivers or other geographic names, please let me know and I will make appropriate changes. I plan on adding information on type species for each genus and a list of currently recognized species/taxa in the near future. An example of the kind of added information can be seen in the account for the genus Castalina . If anyone has any comments on how and what type of data to include in these species list sections, please let me know. I am still playing around with the format. Also understand that these pages (like many on the web) are "works in progress" and the data contained in them should be checked to the primary literature to ensure accuracy.

89. Atlantic Ribbed Mussel Photographs and information on this species. http://www.assateague.com/ribbed-m.html

Return to Life on the Edge Menu Atlantic Ribbed Mussel (Geukensia demissa) You'll most likely find these edible dark brown mussels projecting from the mud along marsh creeks (guts) and often among the marsh grass. Their shells are distinguished from most other mussel shells by the ribs that line the surfaces. Ribbed mussels are found along most of the East Coast; those in the photo were spotted at the edge of a gut by Toms Cove (see map The mussels attach themselves with tough byssus threads (lower photo, left side) to the marsh grass or other solid objects in the mud. These threads are secreted by a gland in their foot. While many bivalves filter feed through a pair of siphons that draw in water and then expel it, mussels do not. When covered by the tide, mussels open slightly, and cilia, small hairs on the gills, draw in water and the food in itusually algaeto the mouth. When the tide is out, the mussels close, retaining waste products toxic to humans. For this reason, collecting mussels at low tide is usually avoided.

These photographs and videos are intended to encourage interest in the freshwater pearly mussels (Unionoida) and promote the conservation of endangered species. Students, teachers and biologists are welcome to use the images for non-commercial educational purposes (see use policy Winter raccoon kills on the Verdigris River, KS Introduction The rivers of North America are home to nearly 300 species of native freshwater pearly mussels. However, the destruction of river habitats by dams, channelization, erosion and pollution has left many of these amazing mollusks on the brink of extinction. Presently 71 native mussels are on the U.S. endangered species list. Mussels don't have a glamorous public image like pandas or tigers, yet the more we learn more about them the more remarkable they seem. Perhaps the most surprising aspect of native mussels is their symbiosis with fish. Females release tiny larvae called glochidia. The glochidia must attach to the gills or fins of particular species of fish, where they remain for several days or weeks as they metamorphose into juvenile mussels. Mussels have evolved incredible devices to lure fishes and ensure that the glochidia become attached. The photos and videos displayed on the following pages illustrate some of these remarkable adaptations. Click on the photos to link to the image pages.

92. Eastern Lamp Mussel Photographs and information on this freshwater species. http://fcps.edu/islandcreekes/ecology/eastern_lamp_mussel.htm

Eastern Lamp Mussel Lampsilis radiata Eastern Lamp Mussels are freshwater mussels living in streams and rivers. They live in gravel and sand on the bottom. Like most freshwater mussels, the Eastern Lamp Mussel is in trouble. Populations are declining. While this mussel is not on the Endangered Species list in Virginia, it is considered a "Special Concern" species. North Carolina Atlas of Freshwater Mussels North Carolina Atlas of Freshwater Mussels Eastern Lamp Mussels have a long, oval-shaped shell. They are brown on the outside with dark greenish-black rays. Inside, the shells are pinkish. All the pictures on this page show only the shells. A mussel has soft inside parts as well (think of when you've seen the insides of a clam or oyster). An important body part of a mussel is the foot. A mussel's foot is not like your foot. It is a long, muscular body part which can stick out of the shell. A mussel uses its foot to move. A mussel can drag itself over the sandy bottom by pulling with its foot, much like an inchworm moves. You can often see "trails" that mussels leave when they move. They also use their foot to burrow down into the bottom.

Contents History of discoveries Anatomy Distribution Ecology ... edit History of discoveries Before 1952, these organisms were known only from the fossil record, ranging from the early Cambrian to the mid- Devonian periods (ca. 550 - 380 million years ago). The first captured living monoplacophoran was Veleropilina zografi in 1896, but it was considered to be an archaeogastropod . This species was revealed as monoplacophoran 87 years later in 1983. In April 1952, a living specimen was collected from deep depths in the Middle America Trench off Costa Rica 's Pacific coast.

97. Cuttlefish: The Sentient Cephalopods This page includes a true story of human-cuttlefish interaction, and several photographs. http://www.heptune.com/cutfish.html

The Cuttlefish of Sentosa by Brenna Lorenz Reproduction of any part of site without express permission is strictly prohibited. All photos of the cuttlefish of Sentosa are by Brenna Lorenz. South of the city of Singapore is an island called Sentosa. Sentosa has been converted into a tourist haven, and you can reach it by cable car. The most interesting attraction there, for us, was the aquarium. These cuttlefish live there in a huge floor-to-ceiling tank. When we first approached them, they were all lined up, hovering, facing us, watching the tourists. Some of them lurked back in the rocks, others were closer to the front of the tank, but all of them were facing the same direction. Except for the undulations of their fins and the languid posturing of their tentacles, they were motionless. Their bodies rippled with changing color patterns. We all stood and stared at them, and they stood and stared back at us. We found the positioning of their tentacles fascinating. It looked so purposeful. We speculated as to whether they were communicating among themselves with the color changes and the tentacle positions. One of us suggested that we try talking to them using our fingers as tentacles. Each of us came close to the glass, put our fingers in front of our faces, and arranged our fingers in gestures similar to theirs.

Home Anatomy Species Travel Books ... Your Ad Here Also known as the ‘Devil-Fish’ due to the terror their strange appearance caused early sea-farers the Octopus or “Eight Footed” cephalopod refers to the Genus Octopi, which are members of the Phylum Mollusca of the class Cephalopoda, order and family Octopoda. Characterized by their having eight “legs” which are more accurately referred to as arms, a lack of skeletal structure and unique locomotion capabilities the Octopus is an often misunderstood and much maligned creature. Each of the octopus’s arms have two rows of suction cups each of which has ‘taste sensors’ to allow it to identify food. It is able to distinguish different textures and tastes with these sensors. With the ability to regenerate lost arms and an eye on each side of its head Octopi are hardy predators with unique self defence mechanisms and very good eyesight. Octopuses have acute vision and are able to detect colors. Just like the human eye, the octopus eye consists of a light-sensitive retina, lens and two fluid-filled chambers. They are however deaf due to the fact that they lack hearing organs. Most Octopi have a globe-shaped ‘head’ or mantle that contains all the vital organs and mouth which hold a sharp beak which is used to kill and decimate prey. The brain is highly developed and they are able to learn fast. Their skin is smooth and ranges in color most normally from a tan to light brown with some coloration, but many are able to change colors by contracting skin cells filled with pigments to allow it to hide when hunting for prey. Some Octopi can even mimic other fish and objects, and their defensive arsenal includes the ability to squirt an ink like substance at an attacker to mask their getaway.
