The specimens in the Echinoderm Collection can be used as teacher demonstration models or can be dissected by students working in groups at separate stations. Five Echinoderm specimens from 4 different Echinoderm classes are provided in individual containers for observation and dissection. Students compare symmetry, locomotion, and feeding styles as well as structures dealing with the digestive, reproductive, and water vascular systems. Includes teacher's manual and student guide containing reproducible blackline masters, background information, dissection guides for each of the 5 animals, and reflection questions.
Important Notice: The supply of dissectible starfish specimens is limited due to a decline in natural populations of starfish, which has been attributed to sea star wasting disease. This disease, thought to be caused by a virus, has decimated populations of starfish along the East and West Coasts of the US. Future availability is uncertain at this time, as population recovery of these keystone species is critical.
