Now a little lesson here -- conch basically means shell as conchology is the study of shells. So a pretty meaningless name which is why we should use the scientific names even though I won't (my father is definitely rolling over in his grave at this). Mollusk is also another generic name for shell. Malacology is also the study of shells.
Taxonomy is really the science of classifying "things" so that everyone was speaking from the same page when referring to critters. So the names I am putting on these shells are the common names from the Southwest portion of Florida. The same shell is probably called something different in Nassau or Puerto Rico!!
I have chosen gastropods for today (foot shells that only have one shell, an animal and then another piece of shell called an operculum which covers up the animal when he is resident). Many times you will find the most beautiful shells empty of their animals but which have a hermit crab resident. They seem to pick the nicest ones and as one only collects dead things, they get thrown back in the ocean.


These are the very common lightening whelks. They are the only of the spiral shells with a opening on the left (ie, if you pick it up with your hand in the opening, you would use your left hand). They are very colorful and varied as you can see here and range in size from very small to about 5 inches.

These are called true tulips as opposed to another very similar shell which is called the banded tulip. True tulips tend to be more one color all over while the banded ones have very definite well defined stripes. True tulips are larger as well and I have seen many live specimens this year that are about 5-6 inches in length. You usually see the banded tulips only a couple of inches long.



This is the very common fighting conch which you find alive on the beach constantly. As they stay in the sun for awhile, they get lighter and lighter in color . You can find this in about every size up to about 4 inches long. The one on the far left has a deep purple on the inside which was a little usual for coloring. I have tiny versions all the way up to very large versions of this shell.



These are probably my favorites -- the Florida alphabet cones. The largest is about 3 inches and I have a couple of gorgeous ones at home too. There is also a gold banded cone which has more consistent gold coloring around it but not as pretty to my eye! I have a couple of those but they are lost in the bag of shells I have here. I saw a large colony last year of alive versions of these beautiful shells. I always pick up the shells to see if they are alive or not. Some of my best finds have been shells that I am sure people think are alive (after awhile you get tired of picking up shells thinking they are not alive and they always seem to be). The biggest of these was half buried in sand right at the water's edge and had been seen I am sure by many people.
