Beachcombing

Looking at what the sea has washed ashore is a fun and educational activity for adults and children alike. There are lots of interesting things to look out for no matter where your local beach is. These brown, spiral-shaped egg cases are quite distinctive.

Female Port Jackson sharks wedge them into gaps between rocks, where they harden and can stay for up to a year before the baby shark hatches. Sometimes they are dislodged by storms and end up on the beach. The adult moon snail is a small brown and fawn snail that hunts in intertidal areas for little bivalve creatures. Abalone have one flattish shell with a row of holes along one side to help them breathe.

They live in groups in sandy or muddy sediments, and true to their name, the edges of their shells can be very sharp if you step on them. Paul Gammy 1 hr. North Yorkshire coast of England.

By George Winter 1 October In August this year, a year-old woman picked up an object from a beach on the banks of the Elbe, near Hamburg, Germany, mistaking it for amber. She put it in her jacket pocket, laid the jacket down… and her pocket combusted.

The object was white phosphorus from a second world war incendiary bomb.

White phosphorus is an allotrope of phosphorus in a tetrahedral structure with size single P—P bonds. Today its use is banned as an incendiary weapon, although it is still widely used to create smoke screens.

There have been at least four cases of white phosphorus burns on beachcombers around the Baltic sea. All had confused white phosphorus ammunition residues with amber while walking on beaches at the Baltic Sea coast, sustaining serious burns after placing clots of phosphorus in their trouser pockets. A year-old woman sustained full-thickness burns from white phosphorus picked up on a Tel Aviv beach in Israel.
