A sheet of seashells: scallops and clams, spiral whelks, sea urchins, small starfish and sprigs of coral — more than twenty of them scattered across the page. Because each shell is small and stands on its own, the sheet suits short sessions: color one or two now and come back to the rest later. Free to download and print, with no registration.

Do you have memories of digging for clams on the tidal flats?
Did you ever collect shells along the shore?
Do you like clams steamed in sake, or in miso soup?
Do you own any pearl jewelry, or have you ever given some as a gift?
How do shells get their patterns?
The shell is built by the mantle, a sheet of tissue that lays down calcium carbonate along the growing edge. Changes in the season, and in how fast the animal is growing, are recorded as bands and stripes — a little like tree rings. The coil of a snail shell is a logarithmic spiral, often described as a “golden spiral”, though real shells follow their own proportions and rarely match that ratio exactly.
Which shells do people gather on the tidal flats in Japan?
Asari, the Manila clam, is the most common, living in sand and on tidal flats. Hamaguri (hard clams) and bakagai — sold as aoyagi — turn up as well, and shijimi, a small clam, is gathered where fresh water meets the sea. Asari is the most versatile in the kitchen: miso soup, steamed in sake, or tossed through pasta.
How is a pearl made?
When something irritating works its way inside the shell, the animal wraps it in nacre — the same material that lines the shell — layer upon layer, and a pearl forms. Cultured pearls grown in akoya oysters are associated above all with the Shima area of Mie Prefecture, where the technique for culturing round pearls was first brought to success.
