- Field guideHow crabs molt and growBecause a hardened crab shell cannot stretch, growth comes in steps. The crab prepares a larger cuticle underneath, leaves the old shell, expands while the new one is soft, and then mineralizes and strengthens it.
- 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 guideHow mantis shrimp seeMantis-shrimp compound eyes are mobile mosaics with specialized retinal regions. Numerous receptor channels sample visible, ultraviolet, and polarized light, but receptor count alone does not mean finer color discrimination than humans have.
- Field guideWhy flamingos are pinkA flamingo is not born with an adult pink coat. Food-web carotenoids enter its digestive system, are metabolized into pigment forms, and reach developing feathers; chicks begin gray or white, and adults renew colored plumage during molt as diet and physiology shape the resulting shade.
