ANCIENT SEASHELLS UNDER ULTRAVIOLET LIGHT PROVE TO BE STRIKINGLY COLORED - NOT DRAB AT ALL!
DISCOVERY - ANCIENT SEASHELLS SPORTED FLASHY COLORS by Jennifer Viegas
Hendricks cleverly placed the drab-looking old shells under ultraviolet light. In doing so, the organic matter remaining in the shells, which date to 6.6–4.8 million years ago, became visible. It revealed the original coloration patterns of the shells that encased the large marine snails.
Using this technique, Hendricks was able to view and document the coloration patterns of 28 different cone shells, 13 of which are now suspected to be new species. One of the most striking examples was a polka-dotted shell. This unmistakable pattern is thought to be extinct among modern cone snails.

SHOULD YOU BE COLLECTING SEASHELLS?
As a girl collecting and trading sea shells with other kids was a lot of fun. Gradually I learned that a proper shell collection is not just full of shells you've IDENTIFIED but also information on when and where they were found.
If you went to any beach resort you could buy bags of sea shells. Most of these shells were dredged from the sea.
Those were the days when people were not at all concerned about ocean ecology, under sea life, or the massive floating sea of plastic in the Pacific ocean. (If you want to read more about the Sea of Plastic in this Google Blogger, use the search engine to bring up older posts!)
Once I started collecting shells I learned that dredging for shells was the way that many collectors got their specimens - and of course the animal that lived in the shell was killed. There were instructions on how to kill it, and how to remove it's dead remains from the shell so it wouldn't smell.
These days I don't believe in collecting sea shells unless you find one already dead and washed up on the beach.
I believe we need to leave sea life where it belongs, in it's own ocean environment.

Did you know that our nation's biggest museum, the SMITHSONIAN, has the largest collection of sea shells?

POPULAR SEA SHELLS COLLECTING : DO NOTE WHEN AND WHERE YOU FOUND THE SHELL
I collected sea shells when I was a child and I did so without ever going to the beach! Sea shells were TRADED in my neighborhood like baseball cards!
Now I know that a very important part of collecting sea shells is to carefully note when and where a shell is found. This can reveal important information about the life of shelled creatures under the sea including the effects of tides, fishing and pollution!

SEASHELLS ARE NOT AS COMMON AS THEY USED TO BE - MAYBE IT's TIME TO JUST SKETCH THEM!
SEASHELLS are disappearing off the shores and going to the beach even in the early morning will not guarantee that there are shells to be collected. That means that there are fewer shelled sea creatures living under our oceans.
One of the reasons for this is dredging or harvesting shells by scraping the bottom of the sea and hauling them aboard a ship.
Limit your collecting to what you personally find washed up on a beach. Or take a sketch book with you and draw what you see!
It's lovely to have a row of jars full of beach finds - sea glass and holed stones - scallops and muscles - the occasional univalve - lined up on a shelf. These can be full of memories of a wonderful day at the beach. But remember sea shells are part of the natural world that usually reclaims itself.
DO NOT PURCHASE SEA SHELLS FROM STORES !

SHELL - UNIVALVE
The value of a sea shell depends on many things, including the year it was found and where. As a child I loved those bags of shells. As an adult, I know those shells are dredged up from the sea, and that many places that once had vibrant sea shell life off shore no longer do...
