Paper Nautilus

windgrrl - 1-15-2011 at 09:20 AM

...found on my walk along the shore near Los Barriles about an hour ago. I spotted it's resident a few yards away before spotting the shell and had returned it to the sea.

It's a beautiful find.....great way to start the day!

Paper Nautilus are beautiful! Because they're so delicate & fragile, it never ceases to amaze me how they can make their way up onto the beach intact! Kudos for putting it's former resident back in the ocean!

A lot of years ago I went out to Magote and there were a lot of the Paper Nautilus. I suppose there are quite a lot of people there now looking for them.
edit: better photo

Windgirl, Hope you don't mind but I enhanced your photo a bit...

These are at the very top of my want to find list.

Usually a beachcomber's delight in late March early April out on the outer beaches of the Mogote and the islands. Picked up a bucket full one time. The shell is an egg case for a little octopus and when the eggs are released it ends up on the beach. Many are broken by gulls as they sometimes contain some eggs. I have collected some as large as 10 inches, but the increased surface area on larger ones means they break easily in the surf. I hatched some residual eggs and under a microscope the little octopus looked like something a fish would like. Sadly, the development Paraiso del Mar on the Mogote has greatly reduced the bird population and increased the shell collectors (besides being ugly).

Only place I've seen these were the beach at Ensenada de Muerte (?), just to the north of Punta Chivato.

Beautiful pictures. Their distant relative the chambered nautilus is also very beautiful:

wow-love these photos-thanks. Are there alot of sand dollars down south as well? I ask because perhaps 2x a year where we are you can walk the beach and see virtually thousands of them-and the next morning they are gone

I found a papered Nautalis shell on the beach in Bahia de Los Angeles this year, very beautiful and fragile.

why are they called "paper?" because they are so delicate? so when the crab dies the shell gets inhabited by an octopi who lays eggs in it. why wouldn't another crab move in, like hermit crabs who are constantly upgrading?

very cool subject. who knew BN was educational?:lol:

Yes, delicate and paper-thin.

Nothing to do with crabs...the octopus secretes (constructs) the egg case, lays the eggs, carries the egg case sometimes including a small male. When eggs hatch, egg case is discarded to end up on the beach. Related to snails, etc. it is a mollusk.

i figured the octopi were just finding a place to secrete their eggs. pretty cool that they create this shell.

Thanks for improvement, Russ.

Krafty - occasionally, there are a few small sand dollars, sea biscuits and free-swimming octopi around the same area.

Nature at her best!!!

The recent winds and swell have washed a great number of shells onto the beaches out by San Juan De La Costa. My wife found one almost identical to yours, plus several large conche shells. Made her day! She is developing a large collection used as borders around her plants out around the house.

I found one shell about a mile south of San Nicolas, maybe 20 years ago.
A lady asked me about it, I would have given it to her had she asked, stories and fishing a long time ago.
I thought they were something washed on the beach from the trawlers.
I also thought they were mostly from the southern hemisphere.

I found some at the southern end of Isla San Jose. Interesting to hear of where these have been found, and glad to hear they can still be found! Viva Baja

Russ - 1-17-2011 at 10:25 AM

Searched the beaches around here yesterday, the first calm morning in days, and no luck. I think it is still the early part of the season for them so will keep searching when I'm out surf fishing.

windgrrl - 1-20-2011 at 09:15 AM

Found another, smaller Argonaut in the same spot today. Very calm here also red tide present.
