Is a tarantula diploblastic ortriploblastic

Tarantulas are triploblastic organisms, meaning they have three primary germ layers: ectoderm, mesoderm, and endoderm. This classification places them in the category of bilaterally symmetrical animals, which also includes most arthropods and vertebrates. Diploblastic organisms, on the other hand, only have two germ layers (ectoderm and endoderm) and are typically found in simpler animals like cnidarians.
