In this season of strange presents from relatives, Dorothy Ferreira got a doozy the other day from her 82-year-old sister in Waterloo, Iowa. It was ugly. It weighed four pounds. There was no receipt in the box.

Inside she found what looked like a gnarled, funky candle but could actually be a huge hunk of petrified whale vomit worth as much as $18,000.

“I called my sister and asked her, ‘What the heck did you send me?’ ” recalled Ms. Ferreira, 67, who has lived here on the eastern tip of Long Island since 1982. “She said: ‘I don’t know, but I found it on the beach in Montauk 50 years ago and just kept it around. You’re the one who lives by the ocean; ask someone out there what it is.’ ”

After researching ambergris on the Internet, Ms. Ferreira’s neighbor, Joe Luiksic, advised, “Put it on eBay.” But endangered species legislation has made buying or selling the stuff illegal since the 1970s; a couple who found a large lump of ambergris valued at almost $300,000 on an Australian beach in January has had legal problems selling it.

“If I get locked up, will you bail me out?” Ms. Ferreira asked her friends.

Ambergris begins as a waxlike substance secreted in the intestines of some sperm whales, perhaps to protect the whale from the hard, indigestible “beaks” of giant squid it feeds upon. The whales expel the blobs, dark and foul-smelling, to float the ocean. After much seasoning by waves, wind, salt and sun, they may wash up as solid, fragrant chunks.

Because ambergris varies widely in color, shape and texture, identification falls to those who have handled it before, a group that in a post-whaling age is very small. Ms. Ferreira says she has yet to find an ambergris expert.

“A hundred years ago, you would have no problem finding someone who could identify this,” said James G. Mead, curator of marine mammals at the Smithsonian Institution, who said he hears of new ambergris surfacing somewhere in the world maybe once every five or six years. “More often, you have people who think they’ve found it and they can retire, only to find out it’s a big hunk of floor wax.”

At $10 per gram, Ms. Ferreira’s chunk, according to a neighbor’s kitchen scale, would have a value of $18,000. “The only way to positively identify ambergris is to have experience handling and smelling it, and very few people in the world have that,” Ms. Beuse said. “Certainly, if she has it, it’s like winning a mini-lottery.”

Larry Penny, 71, director of East Hampton’s natural resources department, said he had no way of making a definite determination, because “we don’t keep a certified whale-vomit expert on staff.”

“The older folks would always tell us, ‘Keep your eyes open for that whale vomit because it’ll pay your way through college,’ ” he recalled. “We used to bring home anything that we thought looked like it, but it never turned out to be ambergris. The average person today could trip over it on the beach and never know what it was.”

In “Paradise Regained,” Milton describes Satan tempting Christ with meat pastries steamed in ambergris. In “Moby-Dick,” Melville called it the “essence found in the inglorious bowels of a sick whale.”
