A book covering a six year study of dolphins in the Bay of
Gibraltar, with fabulous photographs and an account of how it was
carried out, as well as memorable moments and the findings. 'A
dolphin acknowledging your presence is always a humbling
experience. It reaffirms the link between both parties and the fact
that everyone concerned is a willing participant. A situation like
this exposes the fragility of such a relationship as, with a flick
of its tail, it can swiftly disappear into the sea.'
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.
