Flotsam

Half a coconut

With a Red Sea Hare inside!

Exterior of the shell (I was careful not to tip the slug out)

Another slug

Weird seaweed(?)

Or possibly a tunicate

Some fellow beachcombers:

Godwit

Tern

Plover

Dark-eyed Junco

I have never seen a bird with this many leg bands. Has it been captured, tagged, and released by researchers four times? Where has it wandered, and what is its story?
