Collectors should familiarize themselves with local regulations.  In some areas, such as parks and marine sanctuaries, collection of shells and other marine organisms may be restricted or prohibited.

STARTING A COLLECTION. . .HERE’S HOW

Knowing where to look for shells you probably wonder when is the best time.  The answer is anytime.  Mollusks know no season.  Some species appear suddenly for several days and then vanish; others can be found almost anytime.  Most mollusks appear at night, but others work only in the daytime and go out of sight after dark.  The tides may have something to do with it.  So does the weather—­ it can be hot or cold, dry or rainy.  While you won’t find the same shell at all times, you’ll find a great variety at any time.

What to take?  The things pictured on page 8 should be enough.  If you’re going out on the coral reefs along Florida, it would be wise to keep your legs covered as protection against stings or scratches.  Don’t ever forget to wear some kind of shoes in the water.  Even though you’re wearing a mask or goggles, take along a gig or some slender stick and feel your way along so you don’t fall into a hole you can’t see in the deceptive near-tropical waters.  If, despite precautions, you get a sea urchin’s needlelike spine broken off in your skin, soak the wound in vinegar which will dissolve the fragments and stop the pain in a few minutes.

Tiny shells buried in sand can be netted in your sieve.  Clinging ones must be chiseled off rocks.  Frail, delicate clingers should be gently nudged loose with tweezers.  Submerged sandbars are good spots to find several kinds of univalves and bivalves, but the latter will dig themselves quickly out of sight—­as far down as several feet.  When you see one going underground, don’t dig directly over it—­you might break its shell.  Instead, dig to one side, and break the mud or sand away with your hands.

After you’ve had a good day’s haul and a rest (you’ll need one) you must clean your shells.  Put your tiniest, most fragile ones in rubbing alcohol.  Put the rest in a pot of fresh water and slowly bring it to a boil.  Let them cool in the water slowly to prevent the glossy shells from cracking.  When cool, your bivalves will be gaping open; simply scrape them clean.  Your univalves will be more difficult; remove the animal with a crocket hook or other piece of bent wire, turning it gently with the spiral; try to get it out whole to save yourself trouble.  Save the univalve’s operculum and slice it off the muscle that holds it.  It will preserve indefinitely and is a valuable part of the shell.

Clean the shell’s exterior by scraping it gently with a dull knife or nail file, then soaking it in a Clorox solution (1 cup to 2 quarts water) for two hours.  Some will be covered with an ugly skin—­scientists keep this intact and you should try to.  The best collection has two of each species—­one with and one without the epidermis.
