Study Evolutionary Development

  • Starfish eggs are large and components are clearly visible
  • Great developmental biology subject
  • Investigate egg cleavage stages
Starfish are invertebrate deuterostomes and are related to chordates, the clade that includes vertebrates. Because of this, starfish make good subjects to study developmental biology from an evolutionary perspective. Starfish eggs are large and usually transparent, making the developmental processes easier to observe for researchers and students. We offer individual starfish slides in varying stages of development.

Ordering information: Available individual starfish development slides include Starfish, Unfertilized Egg (wm)- Large ovum with yolk evenly distributed; Starfish Egg, Polar Body (wm)- Fertilized starfish egg with polar body; Starfish Egg, Early/Late Cleavage (wm)- Starfish egg with early/late cleavage; Starfish Egg, Late Cleavage (wm)- As cleavage progresses, blastomeres decrease in size and the segmentation cavity begins; Starfish, Blastula (wm)- Displays large blastocoel; Starfish, Gastrula (wm)- Shows development of deuterostome, or second mouth. The mouth forms as a secondary opening at the opposite end of the blastopore; Starfish, Late Gastrula (wm)- Shows formation of coelom as the development of two large lateral pockets that eventually separate from the archenteron; Starfish Bipinnaria Larva (wm)- First stage of larval development; Starfish Brachiolaria (wm)- Brachiolaria larva of starfish. Demonstrates the long, delicate projections and adhesive discs characteristic of this larval stage; Starfish Embryology I, Composite (wm)- Unfertilized egg through gastrula; mixed forms; Starfish Embryology II, Composite, (wm)- Unfertilized egg through bipinnaria larva; mixed forms; and Starfish, young transparent (wm)- Asterias. Young, transparent starfish just after metamorphosis.
