A quick little share of this pretty gray banded tulip shell found on a recent boating trip.

Shells Found on a Deserted Beach
Found lots of knobbed whelks on this deserted island beach in Mosquito Lagoon. And a few other pretty shells.
A Trip by Water
I wrote a post about our trip down to this island on a previous post, “A Beach All Our Own”.
Now I want to share some photos of the shells we found on this deserted beach.
The water was very clear right near shore. The darker part is where the grass is growing.
The Island Beach
We, my son, daughter and me, visited this Spoil Island in October, after Hurricane Ian, which hit our area the end of September. It is likely that many of the shells we saw had been uncovered by the waves. The beach erosion, and tree in the water, was most likely from that storm.
Shells We Found
I’ve never found so many knobbed whelks in one place. In fact, I rarely find knobbed whelks on our normal boating trips. But this island had many. None were in perfect condition, but they were also empty, so I collected a few.
There were hermit crabs on this island. The crown conch and tulip shell (pictured below) both contained hermits, so I got photos and left them alone. A hermit crab would need to be quite large to live in, and carry, a heavy knobbed whelk shell.
The angel wing shell is encrusted with hard sand that doesn’t come off. Quite a few of the shells and pieces are a pretty pink-orange color, and a few were yellow.
The two gray scallop shells are very interesting as they differ in appearance.
Finding the Creepy Face
My daughter was beach combing at the front of the islands on the rocks, and called me over. As she went to hand the shell (face) to me, it fell on the ground. Because she dropped it, we thought it didn’t want to come with us. I brought it home anyway and it’s in my garden. I was going to sneak it into her suitcase to creep her out when she got home and unpacked. But I like it too much and wanted to keep it. The Face is now watching over my raised bed garden.

What to Do About Noisy Neighbors at a Campground
How do you deal with obnoxious and noisy neighbors at a campground? As campers, we all have had to deal with this problem, or will have to.
Well, They (the Northerners) Are Gone
It is June and I am here in Florida for the summer. The snowbirds (northerners) have gone, and at least maybe the roads won’t be so crowded now.
First Time Camping at Anastasia State Park and It Was…
We recently camped at Anastasia State Park in St. Augustine, Florida. It did not disappoint with a beautiful, uncrowded beach and nature enclosed campsites.

Selling the Camper and Wondering Why Didn’t I Buy Used?
It’s time to sell our camper and downsize. It has me wondering about buying new vs. used. I’m all about saving money, and I could have saved a bundle…

Collecting Seashells: Grouping the Bivalves
The bivalve seashells, or shells that come in two parts or halves, can be similar in appearance, but not all bivalves are “clams”. I’m not scientifically minded, but I’ve been learning the difference between the shells I collect and photograph.
I’ve gathered some photos of the more common bivalves I see on beaches and in the saltwater rivers around my area of Florida. A general bivalve list includes: clams, oysters, scallops, cockles and mussels.
Clams and Arks
My photos below in this section contain various types of clam shells. Also, there are many types of Venus clams and loads of coquina clams. Shells called “arks” are also clams.

Oysters
I rarely collect oyster shells but we see oyster beds while out on our boat. Oyster shells are sharp, and are the scourge of boaters because they can slice up the underside if a bed is accidentally hit while running. While walking the flats in oyster areas I can hear the shells snapping as they feed.

Scallops
Scallop shells can be some of the prettiest shells. Certain types of scallops have one flat side and the other is normal / rounded. The concave part is in the sand or bottom and the flat part is on top and opens like a flap when the scallop is alive. Scallops propel themselves around by opening and closing their shells.
The Kitten Paw and larger Lion’s Paw shells are also scallops. I found these Kitten Paw shells while visiting Sanibel Island on the Gulf coast. I’ve never seen any where I live on the east coast.

Cockles
Cockles are not clams although they look similar. Because they have an oval shape with high top part (umbo), when a whole cockle is viewed from the side it resembles a heart. For that reason, they are known as the heart shell or heart cockle.

Mussels
Mussel shells are something I rarely collect or photograph because they really are not great looking shells. They are dark colored and shaped like thin fans. The pen shell is distantly related and I have a few pictures here. The pen shell can be nearly a foot in length and is more impressive than a mussel.
