I had packed my blue mesh bag (above) but had forgotten to toss the shell-net-on-a-stick into my suitcase prior to departing home. While in Fort Lauderdale, I bought a child’s version (the stick is shorter, and it’s plastic). So I was all set to do some shelling.
They do not have formal “swales” here in Caye Caulker; they have what look like naturally-carved ditches that run down to the sea to drain off the rain water. Looky what gets trapped in them!
You can see some sea snail shells here, as well as bits of branch coral.
