Description

Students can watch the fascinating life cycle of sea urchins right in your classroom with these 14 fertile urchins (our choice of Eucidaris tribuloides or Lytechinus variegatus). We guarantee at least 50% of the urchins to be ripe on arrival and recommend that they be used the day of arrival or immediately the next day to avoid reabsorption of gametes. Early cleavage through pluteus larvae. Urchins are not sexed, but the male-to-female ratio is typically about 1:1.
