Whenever I have walked to or from the subway this last week, a particular patch of pavement stands out because it has been dyed a ghastly blackish purple. This is where the sidewalk runs beneath a mulberry tree, a medium sized deciduous fruit tree which produces copious quantities of black multiple fruit. Ten to sixteen species of trees are accepted by botanists as true mulberries. The three most commonly known species are black mulberries (Morus nigra) which were exported in great number from Southwest Asia to Europe, the red mulberries (Morus rubra) which grow wild in Eastern North America, and the white mulberry (Morus alba) which has been domesticated since ancient times in China as food for silkworms. The different species readily hybridize into fertile hybrids so I have no idea which sort I am walking under every day. The Mulberry trees give their name to the Moraceae, the mulberry family, which includes figs, banyans, breadfruits, and Osage-oranges.
Mulberry foliage is the preferred food for silkworm larvae (although the caterpillars will also tolerate foliage of the Osage-orange and the tree of heaven). An ancient Chinese legend relates that Lei Zu, the wife of the Yellow Emperor (himself the mythical progenitor of Chinese culture), discovered silkworm cultivation as she was drinking tea beneath a mulberry tree. A silkworm wrapped up in a cocoon fell into her tea. She removed the cocoon from her beverage and was amazed at how the fiber unwrapped around her fingers as a lovely thread.
Mulberry leaves, sap, and unripe berries contain 1-Deoxynojirimycin, a polyhydroxylated piperidine, which acts an intoxicant and mild hallucinogen (and produces nausea). However when mulberries ripen they turn black and become edible. Mura nigra and Mura rubra allegedly have the tastiest fruit which is said to resemble blueberry in taste and appearance when cooked into pies and tarts. Cooked mulberries are rich in anthocyanins, pigments which are useful as natural food colorings and may have medicinal value.
Mulberry also gives its name to a lovely purple pink which resembles the color of mulberry jams and pies. The word mulberry has been used to describe that particular shade since the 1770’s. I remember it fondly as a Crayola crayon which I always used up before the others (although apparently the color was discontinued in 2003–so today’s children will have to make do with less poetic purple pinks).
In the past this site has featured posts about how some of my favorite organisms and mythical beings have been used as mascots or logos. I have blogged about turkeys, leprechauns, trees, and catfish as adopted as the symbols for businesses, sports teams, or individuals. These posts have been fairly open because mascots and logos are often loosely defined: sometimes an informal name catches on or a novelty statue becomes the symbol of a town. Indeed some of the images I included are only maniacs in costumes or striking illustrations. So be it! Such usages highlight the way in which these animals and concepts are worked into the fabric of our lives.
None of this prepared me for how mollusks have become mascots, logos, and symbols. One of the many reasons I write about mollusks is because they are so alien and yet simultaneously so pervasive and familiar. That idea is borne out by mollusk symbols! Not only is one of the world’s largest companies symbolized by a mollusk (to say nothing of how a squid has wiggled its way into becoming the unofficial mascot of one of the world’s richest and most controversial financial entities), some of the world’s strangest entities are also represented by octopus, squid, or shellfish.

Mollusk logos are immensely popular in Japan. Sometimes the reason is evident (as in squid flavored noodles with a cartoon squid on them), but other times the reasoning is elusive. Mollusks in Asian art deserve a post all of their own. Indeed the subject deserves more than that—for tentacles are so tangled up with fertility issues to the fervid Japanese imagination that my family blog is not going to explore some of the outré fringes of mollusk imagery in that island land. With that explanation (or caveat), here are some particularly good Japanese mascots–denied of any context since I don’t read that language!

Actually I have no idea if those last five are mascots or logos or what. Whatever they are, they come from Shinici MARUYAMA and they are jaw-droppingly incredible. The Japanese certainly have a very special relationship with mollusks!
