Small Seashell Treasures, Big Shelling Fun

Posted by: | Comments (17)

mauve mouth drill shell pile

From Bowman’s Beach to Blind Pass, there are nice shell piles with small treasures just waiting to be found. I found the sweetest little MAUVE-MOUTH DRILL sitting in a small shell pile that looked like it had already been raked through and picked over… but there it was. Just waiting for me to appreciate how perfect it was.

So many of these smaller shells look so similar, right? If you can’t tell the difference yet between this and the GULF OYSTER DRILL, please look at my post from February  6 that I compared these shells. You’ll be amazed!

Here are some of my other finds in the surf line at Blind Pass Sanibel…

I saw Amy doing the Sanibel Stoop out in the shallow water just before sunset…

She was having a ball picking up lots of the same jewels I found. Love that pink hat, Amy!

I haven’t found as many shells at the Lighthouse Beach lately (I think I love to watch the wind surfers too much!) but I did meet some very cool gals from Texas, Melanie and Robin who were finding quite a few FIGHTING CONCHS and SCALLOPS.

These are just a few others shells that I picked up (and Clark) from Blind Pass and Bowman’s. I could have filled 10 bags of FIGHTING CONCHS and such but I try to only keep a few shells (and SEA BEANS!) that are special to us.

Oh but lets back up… I’ve been getting questions about the dredging at Blind Pass sooooo…. I made a few calls today to make sure I had the correct info so Mike Mullins of the CEPD said “The county announced at the CEPD meeting last week that they were done.  They couldn’t get the dredge to do the inside, so the inside is quite shallow and there are no plans to do anything further.

So there you have it folks. The dredging is done. Now don’t be alarmed by this next picture of Blind Pass. It has nothing to do with the dredge, it’s just normal beach erosion but it’s quite a ledge (I’m a poet and don’t know it! LOL). We probably wont even see this next week, but I’ll try to run down there to give it a peek. (Sorry I couldn’t help myself with another rhyme 😉 )

Similar Small Sanibel Seashells

Can you tell that these are four different shells? The difference between these seashells is very slight.

I found a few cutie little shells at the lighthouse that looked very similar but when I turned them over to look at the apertures to correctly identify them, I found little HERMIT CRABS in each one.

 After I took the pictures, I put the shells back in the water where I found them then got inspired to head home to sift through my collection of unsorted shells. I had so many of these smaller shells lumped together so it was time to make sure I had the right identity on each one. Okay, so let’s go back and look at the shells I found in my collection at home that were so similar (but not exactly the same kind I found on the beach)…

From left to right… MAUVE-MOUTH DRILL, RIBBED CANTHARUS, GULF OYSTER DRILL and a PITTED MUREX.  Here are the apertures…

I showed the MAUVE-MOUTH DRILL (and it’s eggs) in my January 24 post …

but now you can see how similar it is to the RIBBED CANTHARUS

 I’ve only showed a GULF OYSTER DRILL once before, which is strange because  they are somewhat common to find on Sanibel. So here’s a closeup…

 The PITTED MUREX is bit smaller (and not as common… for me any way) than the others but it’s still a bear to identify without “cheaters” on. And it is so similar too!

So now we can sift through our collections and finally identify the differences between these four shells now that we can see them side by side. Uhhhh….. I hate to tell you this…. but…. unfortunately, there a few more that look similar to these as well. For instance, …like that photo of my palm with the HERMIT CRAB shells? That top shell more to the left of the photo…. that’s a juvie APPLE MUREX! Doesn’t it look like the rest of the shells? And the shell on the far right side of my palm has a broken base so it’s harder to identify (and I didn’t get a great photo of it) but I’m sure it was a RIBBED CANTHARUS too. And y’all thought Seashell Identification was easy, didn’t you? heehee

Rare Sighting! Mauve-Mouth Drill Egg Case

Posted by: | Comments (34)

mauve-mouth drill egg case

This is so wild. Attached to a SUNRAY VENUS CLAM, were fresh egg cases that these MAUVE-MOUTH DRILLS just produced!

MurexKen found this fascinating nest just after MurexAlice had shown me those cute little MORTON’S EGG COCKLES on yesterdays post (hmmm- the “egg” theme continues, huh?). I was tickled that he called me over to show me this egg case that I’ve never seen before. The babies look like little pods of pollen sitting in a beautiful flower. Mk and MA are quite a pair for finding the unexpected!

I’m not quite sure, but I think the shell on the left was still laying some eggs. I hated to disturb them so after taking a few photos, we returned the mollusks and eggs to the water to make sure they produce healthy babies.

You can see this one’s aperture with just a bit of the “mauve” showing around his body.

Oh wait…. just in case you can’t remember what a MAUVE-MOUTH DRILL looks like when you find them empty on the beach, here are a few pictures to refresh your memory…

Now you’ll see why they call it “mauve-mouth”. They have a mauve or purple in the aperture when they are alive or freshly dead.

Out of all these shells in our collection at home, I could only find one that had a mauve mouth.

I don’t find MAUVE-MOUTH DRILLS that often so to see live ones that are laying eggs was really pretty exceptional. I’m not sure if this would be considered scientifically  “rare” to see this out beach combing, but it was rare for me. Great finds MK and MA!
