Neverita duplicata Shark eye shell identification

Whoa! Shark!

Naaaaa, it’s not the Jaws type shark so you don’t have to get out of the water for this one. Actually you want to get IN the water to see this type of creature… it’s a SHARK EYE (Neverita duplicata or as I always say “Shark’s Eye) seashell. Over the years of beach combing, we’ve been fortunate to have found these shells in so many different life stages to share with you so I thought this was the perfect week to sum up some of the cool things we’ve learned about the SHARKS EYE. Why not… it’s Shark Week!

When this MOLLUSK is still alive, its amazing to see the animal wrapped around it’s shell like we found in my post The No Place Like Home On Sanibel.

Here’s a video of a live SHARKS EYE in action I filmed for a post in 2011

We only see the live SHARKS EYES at low tide scooting around in the sand but we seem to find a lot of empty SHARKS EYE shells washed up on Sanibel and Captiva especially after storms. We started to realize we don’t normally find the operculums. When Clark and I found another live one, we paid closer attention to the operculum to see exactly what it looked like so we could make sure not to miss one washed up on the beach. Why don’t we find them washed up on the beach more often? Dunno exactly but I’m assuming because they are so paper thin that they crumble easily when the animal dies and dries up. They also look like a small piece of broken PEN SHELL or a brown leaf so they are easy to overlook.  Anyway, here’s what the OPERCULUM looks like when it’s attached to the healthy animal still in his shell…

Almost a year after I made this video, low and behold, Clark found our first SHARKS EYE OPERCULUM washed up on the beach.

We’ve also seen juvie live SHARKS EYES sliming around finding their way…

We’ve seen lots of other live babies scooting around at low tide on Sanibel along with teeny tiny eggs in the SHARK EYE EGG COLLARS.

This is what the EGG COLLAR looks like that the female SHARKS EYE lays. If you see a ring like this while at the beach that feels and looks sort of like freshly made hand crafted paper, take a closer look then place it back in the water if that’s where you found it. There are hundreds of itty bitty baby SHARKS EYES in there. Cool, huh?

What do SHARKS EYES eat? They are carnivores who love to make a meal out of bivalves but at times they are cannibals …. so one SHARKS EYE will eat another SHARKS EYE.  (Hmmmm… that happens with the fish type Tiger Sharks too on occasion). You can tell another SHARKS EYE ate this SHARKS EYE in the next photo because it makes a beveled edge hole just like this. CLICK HERE to see that story.

There are two types of these MOON shells that look similar and are hard to distinguish between the two of them. See how much higher the spire is on the shell on the left? The one on the right is a Neverita duplicata (SHARK EYEand the one on the left is a Neverita delessertiana ( FALSE SHARK EYE) I’ll do another post to show you the aperture side so you can see another difference but I usually just look for the “eye” that looks popped out.

Have you heard me talk about the “Paul Newman’s Eye”? Paul Newman was an Academy Award winning hunky actor known for his incredibly beautiful, brilliant blue eyes (I know, funny I thought I needed to explain who he was, right? But anybody under 30 might not know! LOL Oh wait y’all  would know “Newman’s Own”- thats the guy. haha) Anyway, not all SHARKS EYES have a blue center but when they have that handsome brilliant blue “eye”… it’s called a PAUL NEWMAN’S EYE.

See how many different sizes and patterns they have. Gorgeous!

I had so many nice comments on my last post about the differences in SCALLOPS and that y’all really like my educational posts. Me too! I have oodles of photos and gobs of great information about shells AND beach bling that I’ve built up over the years, so I need to start combining them so we all can find the information a little easier. It’ll take a while, but it sure will be fun looking through so many older posts that have been buried by newer posts.

Dont worry, I’ll still post any shelling updates on the beaches but hopefully once a week I’ll pick a shell to research so we can see all the cool stuff we’ve learned over the years.

Lightning whelk in Sanibel surf

If the Sanibel SEA LIFE could have talked last evening at low tide, they probably would have been chatting it up about how lovely the evening was and how healthy they were feeling…. just like us.

The colors of the night were amazing! This clump of SEA SPONGE was the most brilliant color purple…

A little higher on the beach, I saw that Leah from Georgia found a honey hole of wonderful minis which included lots of WENTLETRAPS.

Leah and her husband Matt were vacationing on Sanibel to celebrate Matt’s 40th birthday.

Finding a few beautiful shells to take home was just icing on the cake. Happy Birthday Matt!

The weather was perfect, the beach was teeming with live creatures and each breath of fresh, salty air made exploring the tidal pools heaven on earth.

It has been an unusual week on Sanibel. The winds are changing directions and speed by the second which makes for an interesting site to see of all the different things that wash up on our beaches. I showed you lots of different EGG CASINGS in my last post but I found another one today… a SHARK’S EYE EGG COLLAR…

 Katherine love the minis so she was finding lots of different miniatures like WENTLETRAPS along with AUGERS, CERITHS and a little perfect WORMIE.

I also met another awesome couple while walking on the beach today several miles west of Lighthouse Beach. Here are shellers Linda and Glen from Ohio…

linda glen ohio angel wing

Linda found an ANGEL WING! They also were happy to find their first KEYHOLE LIMPET along with these other goodies. Notice they even collect the broken SHARK’S EYES if the “eye” is still intact. Yep, they really are beautiful. I told them that when the SHARK’S EYE is brilliant blue in the middle that I’ve heard it called “Paul Newman’s eye”. This one is definitely a PAUL NEWMAN’S EYE!

Oh wait… I feel so badly that I never introduced you to Shelly (love that name!) and Kayle whom I met last week at Blind Pass when the weather was a little cooler…

I found a PYGMY OCTOPUS inside a PEN SHELL and Kayle offered to take it out in the water to put it back. So sweet!

Here are Shelly and Kayle’s gorgeous treasures from the sea that they were collecting. Keep the image of this gorgeous PAPER FIG (in the middle of this green bucket) in your mind to leave you with a happy day. See? I told you I had happy happy stuff to show you. :)
