Sanibel’s Captivating Live Sea Creatures

Posted by: | Comments (16)

As we celebrate new days watching the sun rise over the horizon at low tide in the new year on Sanibel…

We also shellebrate the gifts of the sea…

We also celebrate the gift of witnessing living creatures exposing themselves for just a short time as the water recedes.

With most animals, we are easily able to see if they are alive, healthy and breathing but with creatures of the sea that have washed ashore, it’s a little bit more difficult. We (shellers) take the time to to look for signs of life with respect. As soon as I saw this shell was occupied by noticing the body and OPERCULUM of the “snail” still intact, I gently placed it back in the water covered with sand making sure the opening faced down into to sand.

Even for some shellers, it’s hard to tell if a SAND DOLLAR is dead or alive so the best thing to do first is… slow down. Take a few minutes to look for any cilia which looks like fur or looks a little fuzzy in the edges. Any time a SAND DOLLAR is this color, assume that it is still alive… gently place it back in the water.

If a STARFISH is any where near the water or if the sand is still damp where you found it, always assume it is still alive too and let it be.

Shellers are very fortunate to have seen the miracles of Mother Nature as we comb the shorelines to discover the magic of the sea. We learn new lessons every day we walk the water’s edge. For most beach combers, we know the signs of life in sea creatures but inexperienced visitors may be overwhelmed with the beauty that surrounds them and not know to take the time to look for signs of life. Since I grew up on the water, I always assumed other folks knew shells, SAND DOLLARS and STARFISH live their lives close to shore but now I’ve learned that most people don’t know much about life in the ocean or gulf. First time visitors to the beach may have heard how amazing shell collecting is and unintentionally collect a live animal without knowing it. It’s an amazing experience to see the compassion on a new sheller’s face after learning they have collected a live animal then race it to the water where they found it to save its life. Most just don’t know… and are thankful to learn and appreciate the living ocean even more.

There have been so many live critters exposed during the morning’s low tide the last few days so with many newbies on the beaches, I’m sure I’ll get to see the amazement on someone’s face that just learned for the first time that shells, sand dollars and starfish are living beings and are still actually alive.

Can you believe all of these gorgeous shells were found in SouthWest Florida? Yep! I found all of these APPLE SNAILS (Pomacea insularum) at Harns Marsh Preserve in Lehigh Acres, Florida about an hour from Sanibel. For years, I’ve been wanting to go check this place out ever since I met Kathy from Colorado who showed me one of her APPLESNAILS I wrote about in my post “Finally, A Recipe For Finding A Junonia“.

I finally made it to the preserve and was thrilled to find my first one… they are huge!

Just trying to find Harns Marsh Preserve was quite an adventure since there are no road signs- I guess because it’s not a city or state park. So that started the whole journey as quite a treasure hunt in itself. Then once we found it…. On to hunt for APPLE SNAILS! Soul Sister Susan donned her hiking boots, satchel and bug spray while I armed myself with old tennis shoes, long pants and a very strong walking stick. We didn’t know what to expect to find but knew we were going to be walking near marshy water which means (in Florida) there could be lots of bugs, red ants and more importantly… alligators. Errrr… That wasn’t really a “walking stick” …  I would be more inclined to call it my “harpoon” … or should I say “Shellpoon”. Ha! I am a nervous wreck being anywhere near the edge of any inland pond so I just feel a weeee bit more safe with some sort of weapon. It’s better to be safe, right?

We had to park our car at the entrance and walk about a quarter mile until we reached some trees by the water…

Empty APPLE SNAIL shells were lined up all along these trees. SS Susan turned that Sanibel Stoop right into the Snail Stoop.

These APPLE SNAILS are actually an invasive land snail that are not native to Florida and they have threatened native species. They grow and breed very quickly so maybe that’s why we saw so many empty shells laying in the tall grasses just like this….

Their were OPERCULUMS were laying right along the same path. This empty shell had it’s OPERCULUM laying right beside this one.

We got back to the car after a couple of hours and SS Susan dumped her shells out of her bag. OMG Look how many shells! LOL

So cool, right? Some of them may look like they were already cleaned but trust me… cleaning these shells was a grungy job.

I soaked mine for two days in a bucket of fresh water then emptied that nasty water to refill the bucket and shells with a round of fresh water and 1/8 bleach to soak for a couple of hours. You have to be very careful though. Susan said she had picked up some shells that looked like they had spider webs on them and while she was started cleaning them, she saw a big spider in the bucket. Yikes! I didn’t see any siders in mine so I rinsed them all, shot the aperture of the shell with the outside hose nozzle then scrubbed each one with a vegetable brush. I didn’t even have time to put mineral oil on them but I don’t think I they need it. They were naturally this glossy and colorful!

Each one has a different color pattern. So lovely.

This was the largest one and the smallest one I found for the day.

Here are a few of the OPERCULUMS I picked up…

We saw their pink egg clusters on the tree trucks and marsh reeds…

…And even laying in the grasses.

This preserve is really just a water retention area that has become a birder’s paradise since the area provides perfect conditions for so many different species of birds. The APPLE SNAIL is the favorite meal for the KITE SNAIL so you have a better chance of spotting this rarely seen bird at Harns Marsh Preserve … although we didn’t see one. But I did spot this LITTLE BLUE HERON which is the first time I’ve ever gotten to photograph this bird…

We also saw two SANDHILL CRANES!

SS Susan is a GEOCACHER so found a geocache while we were there too.

After signing her geocache booklet, she left one of her APPLE SNAILS in the box as a little trinket.

We brought home such amazing ISLAND APPLE SNAIL souvenirs to remember such a fabulous day exploring a new area, shelling, bird watching and geocaching and learning all while having so much fun spending the day with my friend Susan. Lovely!

Oh but wait… this is weird. Ironically, Clark’s business partner Joe Ginsberg was walking his dog last week in Fort Myers when our local CBS news affiliate interviewed him about these same ISLAND APPLE SNAIL EGGS. They told Joe the eggs are extremely toxic if they are eaten by pets and kids so they wanted to warn folks of what the eggs look like to keep a distance from them. I had no idea that these snails had invaded neighborhoods in Fort Myers … or that Joe was on TV. After Clark told Joe about the APPLE SHELLS I found, Joe told him about the interview. WHOA!

Sanibel Sculptured Art

Posted by: | Comments (19)

Calliostoma euglyptum sculptured top

i Love to find a shell I’ve never found before! This might look like the regular TOP SHELL that we find on Sanibel fairly often but as soon as I picked this shell up, I knew something was different about it. It’ got a nice sculpture about it, right? Look closely and you’ll see the slightly rounded whorls in the side view. I found a SCULPTURED TOP SHELL!

Here is the SCULPTURED TOP SHELL on the left and our “regular” (to southwest Florida) TAMPA BAY TOP SHELL on the right. Now I can’t just say “TOP SHELL” any more… I’ll have to distinguish which one it is when I see it. Cool!

So when I found my SCULPTURED TOP SHELL, I called Clark over to look at it and showed him the wrack line (which is the same as where I found the BABYS EAR and WENTLETRAP in my last post) at TARPON BAY RD beach access. Not one minute later, he looked down and picked this up…

It’s a SHARKS EYE OPERCULUM! Wow! I know it’s not pretty but I’ve always wondered why we never find them on the beach like we find other OPERCULUMS. This is the part of the MOLLUSK that protects it from predators. It’s a MOLLUSK’S front door.

Neverita duplicata operculum

It looks like a brown piece of SEA GLASS, doesn’t it? Well thats what Clark thought it was too when he picked it up and then we figured it out. Call me a geek but I got so excited to finally find one…. errr… well… that Clark found one. But it still comes home with me so I feel lucky too.

It has the shape and pattern of a BABYS EAR but it is paper thin with a slight curve.  Now I know why we dont find many. They are very very fragile once they separate from the MOLLUSK. The edges on both of these are very chipped and ragged and seem like the whole thing will disintegrate any second.

But then he found another one! Dude! We’ve gone forever without ever seeing one and then he pulls out finding 2 of them. Ha!

This past December, I shot a little video of a LIVE SHARKS EYE with his OPERCULUM doing its job of protecting him but I never even showed you because it’s the same day Mimi found her SEAHORSE. The video got lost in the shuffle with all the excitement of the SEAHORSE and then of course, the Christmas holiday. But I have never forgotten what it looked like and I want you to see it too.

Okay, lets go back to the “sculpture” bit…. if you arent as thrilled as I was to finally see what a SHARKS EYE beach washed OPERCULUM looks like, I’ll show you some cool BEACH ART we saw while at Tarpon Beach over the weekend. This artist had quite a sense of humor, man. Funny sculptures!
