I love to display shells around the garden.

Humans have been intrigued by the exoskeletons of mollusks since they first noticed the beauty of  shells their sculpted decorations, delicate colours and patterns. In North Africa Shells have been used to make beads around 100’000 years ago. One of the earliest evidence of human culture.

An exoskeleton  is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as "shells".

Marine cone snails are beautiful but deadly. This marine snail moves at snail’s pace and can not swim, but its sting is instant death.
The snail's proboscis is a hypodermic needle for its venom,  containing up to 200 peptides.
