What two features define animal phyla?
Two features defining the animal phyla are adult body plans and patterns of embryological development.
What are two most common phyla of animals?
Arachnids and Platyhelminthes are two types of animal phyla even though there are many more.
What kind of body plan do most animal phyla exhibit?
Most animal phyla exhibit bilateral symmetry, where the body can be divided into two mirror-image halves along a single plane. This body plan is thought to have evolved for efficient movement and coordination in organisms.
What two animal phyla show radial symmetry?
The two animal phyla that show radial symmetry are Cnidaria (such as jellyfish and sea anemones) and Echinodermata (such as starfish and sea urchins). Radial symmetry means that the body parts are arranged symmetrically around a central axis, like spokes on a wheel.
Which phyla are diploblastic?
Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
What are 2 phyla in the animal kingdom?
There are more than two phyla in the animal kingdom... There are many phyla in the animal kingdom. There are a few phyla of worms and other invertebrates and then you have the vertebrate ohyla. Unless that's what your asking? Did you want the invertebrate and vertebrate in general phyla? That's the only set of 2 things I can think of.

What two animal's have a hard exoskeleton?
arthopoda and mullasca
Is an arthropod a platyhelminthes?
No, arthropoda and platyhelminthes are two different phyla. The latter are the flatworms, the former are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages, and include insects and crustaceans.
What are two characteristic of arthropods?
An arthropod is an invertebrate animal with an exoskeleton , a segmented body, and jointed appendages.

Which of the 9 animal phyla use extra-cellular digestiona nd which use intra-cellular digestion?
actually seven of the 9 phyla use extracellular digestion. the two that are intracellular are porifera and placozoa
Is a sea star a arthropod?
A starfish is actually an echinoderm. Its Its water vascular system and lack of segmentation, or even an exoskeleton composed of chitin, mean that it is not an arthropod in ANY sense...two completely different phyla.
What animal has two bluish-black hard shells?
The mussel, a bivalve, has two valves, or shells.
