Have you ever wondered how fish, whales, dolphins, seals, turtles, plants, and many other things relate? In this fully illustrated book, you will learn what fish eat, and how knowing what they eat can answer many questions. You will learn to draw a food web, linking the species together to understand how an ecosystem works. Thirty-two fish based food webs are included, with a question for each, and answers at the end of the book. Over seventy species of fish, whales, dolphins, crustaceans, and other animals are used and illustrated. From fifth grade to graduate school, every reader will learn something inside. What do sea dragons eat? Why do Orcas sometimes kill great white sharks? What to fruit trees have to do with pink dolphins? Why do snappers follow manatees? Why are crayfish good for recycling? Why are sea turtles important for blue marlin? Why should California crab lovers thank sevengill sharks? Why are silver carp affecting walleye? Suitable as a text for elementary through high school and maybe college biology courses, this book might also make the reader a better angler, and allow you to see the watery world around you very differently.

Easy to understand information about how to start and care for your water garden or pond. You will find details not usually found in other how to pond books, such as how to teach your fish to eat out of your hand. More importantly, specific information on how to avoid the most common pond problems. Plus money saving tips

In November 2002, coastal and fisheries staff from Olympic National Park conducted a four-day inventory of intertidal fishes at San Juan Island National Historical Park. Beach seine sampling was employed in all intertidal zone habitat types associated with the coastal areas of the American and English Camp units. A total of 26 sites were sampled in both park units, with 11 sites sampled in the protected bay habitats of English Camp and 15 in the more exposed coastal habitats of American Camp. Intertidal habitat diversity was relatively low, with most areas dominated by mixed-coarse gravel and sand (American Camp) or mud/silt (English Camp) substrates. A total of 14 species were documented including various baitfish (smelt, herring, sandlance), surfperch, flatfish, sculpins, and gunnels. This project is the first effort to inventory the intertidal fishes of San Juan Island National Historical Park and only represents the assemblage structure found within the limited sampling period.

The leatherback sea turtle (Dermochelys coriacea; leatherback) is the largest and most migratory of the world's turtles, with the most extensive geographic range of any living reptile. This highly specialized turtle is the only living member of the family Dermochelyidae. It exhibits reduced external keratinous structures: scales are temporary, disappearing within the first few months and leaving the entire body covered by smooth black skin. Dorsal keels streamline a tapered form. The species has a shallow genealogy and strong population structure worldwide, supporting a natal homing hypothesis. Gravid females arrive seasonally at preferred nesting grounds in tropical and subtropical latitudes, with the largest colonies concentrated in the southern Caribbean region and central West Africa. Non-breeding adults and sub-adults journey into temperate and subarctic zones seeking oceanic jellyfish and other soft-bodied invertebrates. Long-distance movements are not random in timing or location, with turtles potentially possessing an innate awareness of profitable foraging opportunities. The basis for high seas orientation and navigation is poorly understood. Studies of metabolic rate demonstrate marked differences between leatherbacks and other sea turtles: the "marathon" strategy of leatherbacks is characterized by relatively lower sustained active metabolic rates. Metabolic rates during terrestrial activities are well-studied compared with metabolic rates associated with activity at sea. The species faces two major thermoregulatory challenges: maintaining a high core temperature in cold waters of high latitudes and/or great depths, and avoiding overheating in some waters and latitudes, especially while on land during nesting. The primary means of physiological osmoregulation are the lachrymal glands, which eliminate excess salt from the body. The leatherback was re-classified in 2000 by the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species as Critically Endangered. It remains vulnerable to a wide range of threats, including bycatch, ingestion of and entanglement in marine debris, take of turtles and eggs, and loss of nesting habitat to coastal processes and beachfront development. There is no evidence of significant current declines at the largest of the Western Atlantic nesting grounds, but Eastern Atlantic populations face serious threats and Pacific populations have been decimated. Incidental mortality in fisheries, implicated in the collapse of the Eastern Pacific population, is a largely unaddressed problem worldwide. Although sea turtles were among the first marine species to benefit from legal protection and concerted conservation effort around the world, management of contemporary threats often falls short of what is necessary to prevent further population declines and ensure the species' survival throughout its range. Successes include regional agreements that emphasize unified management approaches, national legislation that protects large juveniles and breeding-age adults, and community-based conservation efforts that offer viable alternatives to unsustainable patterns of exploitation. Future priorities should include the identification of critical habitat and priority conservation areas, including corridors that span multiple national jurisdictions and the high seas, the creation of marine management regimes at ecologically relevant scales and the forging of new governance patterns, reducing or eliminating causal factors in population declines (e.g., over-exploitation, bycatch), and improving management capacity at all levels.
