Do starfish organisms have 3 germ layers?

Here's a breakdown:

* Triploblasty: Animals with three germ layers are classified as triploblastic. These layers develop into different tissues and organs:

* Ectoderm: Forms the outer layer, including skin, nervous system, and sensory organs.

* Mesoderm: Forms the middle layer, including muscles, bones, circulatory system, and excretory system.

* Endoderm: Forms the inner layer, including the lining of the digestive tract and respiratory system.

Starfish are triploblastic, meaning they have all three germ layers, which allows for more complex body structures and organ systems compared to animals with only two germ layers (diploblastic).
