Hermit Crab Poem by Ima Ryma

A hermit crab humans call me,
A misnomer as humans do.
First, not a true crab do I be.
Second, we're quite a social crew.
Like lobsters, I have exposed tail
Which I protect with a borrowed shell.
When an empty shell does avail,
We'll check who it fits most well.
When a new shell best fits me, I
Hand my old shell down to one, and
So we all share the shell supply,
For which are always in demand.

I guess my name no matter makes,
Humans rarely admit mistakes.
