Pond Life "This inexpensive guide is one of the most useful books I've ever owned and my favorite beginners guide to pond life. I can't even say how many copies I've gone through and given away." - Rhonda Wilson
"Nature Aquarium World 2" The second Nature Aquarium World book from Takashi Amano. Mr. Amano's aquariums and photography make him the most celebrated planted aquarist in the world today.
Christel Kasselmann's "Aquarium Plants" is the most complete encylopedia of aquarium plants to date. A must have book for the aquatic plant enthusiast.
Clams live in mud or sand and are housed in a bivalve shell with 2 openings. One pumps in, bringing food, water and oxygen. The other pumps out water and wastes. Clams do not have a head, radula (the snail tongue) or tentacles.
Clams reproduce with eggs. The eggs are retained in the shell of the clam until they hatch and are released as larva. Some clams can release as many as 3 million larva. In some species the larva can be parasitic.
