- Field guideHow snails build shellsA snail does not move into a larger shell. Its living mantle adds material at the aperture and can thicken inner surfaces, so the shell records continuous accretion from the tiny oldest apex to the newest outer lip.
- Field guideWhy sea otters use toolsA hard object can act as a hammer, a portable chest anvil, or a fixed anvil, letting an otter pry loose or fracture prey that teeth and paws alone handle less efficiently. The behavior is flexible rather than compulsory, and it is especially associated with hard-shelled snails and bivalves.
- Field guideHow animals survive droughtBurrows and nocturnality reduce exposure, kidneys and body surfaces conserve water, diet and stored fuels supply some water, and aestivation lowers demand; each strategy trades activity, growth, or reproduction for survival.
- Field guideHow kelp forests support animalsHoldfasts, stipes, blades, and floating canopies add surfaces and shelter from seafloor to sea surface. Grazers consume kelp and epiphytes, detritus feeds animals inside and beyond the forest, and fish and invertebrates use the structure as nursery, feeding, and refuge habitat. Predators can indirectly protect kelp by limiting grazers in some regions.
- Field guideWatching pond lifeA pond is several habitats stacked together. Watch the surface, open water, vegetation, bottom, bank, and air in turn, and a seemingly still patch becomes a web of movement.
