Summary Introduction
To review:
The given blank space in the statement, “lophotrochozoans and ecdysozoans (molting animals) are two large clades of animals that exhibit _____________ development. The other major type of development found in bilateral animals is known as ____________ development, and is present in animals in the clades known as ______________and______________.”
Introduction:
The symmetrical animals either have radial or bilateral symmetry. These animals have true tissues. The difference between bilaterally and radially symmetrical animals denotes a specific branching point in the evolutionary tree of animals.

In Figure 33.2, which two main clades branch from the mostrecent common ancestor of the eumetazoans?(A) Porifera and Cnidaria(B) Lophotrochozoa and Ecdysozoa(C) Cnidaria and Bilateria(D) Deuterostomia and Bilateria
On a deep sea expedition, you capture a previously undiscovered sea creature that appears to represent a new phyla. It happens to have fertilized eggs that you get to spawn. You watch its development to determine which group of animals it might belong to. You see that the mouth develops first, and it goes through several larval stages in which it molts and regrows its skeleton.
Which big phylogenetic group of animals does this animal likely belong to?
A. Ecdysozoa
B. Lophotrochozoa
C. Diploblasts
D. Deuterostomes
