Everything your class needs to witness sea urchins develop is available in this 1 convenient kit. You'll get Eucidaris tribuloides or Lytechinus variegates (our choice). Plus you receive all the materials and instructions necessary for achieving viable gametesand for following development from early cleavage through pluteus. Urchins are ripe at the time of arrival; we recommend that they be used the day of arrival or immediately the next day to avoid reabsorption of the gametes. Not sexed, but male-to-female ratio is usually about 1:1.
