Missing Tentacles Review by
The first set arrived without tentacles and included a large active nematode worm. The company promptly and kindly replaced it free of charge with a second set that did have tentacles but the specimens were very few and small. The fact that it was extremely cold in Vermont with negative temperatures during the night, could have something to do with the problem.
Can't stop watching! Review by
This is one of my faves for all of biology! Seeing these little guys react to stimulus, eat, digest (can still see daphnia while they are inside the hydra!) So much life, see it all with a magnifying glass. Buy them every time I teach biology
