Worms ... sorry no pictures.
Squid - - so far most of the kids' favorite.
And today we tried starfish. Word of caution: the starfish is MUCH more challenging than expected! I, personally, thought this was the grossest one so far! We are finding, as the mothers, that the kids really just want to "dig in" rather than actually see the real stuff inside. The starfish was especially tricky with that and most of them had all their rays cut off by the end of the day! Still, it's been fascinating to learn about different specimen and then cut them all open.
