Segmentation allows for specialized structures to develop in different body segments, increasing the efficiency of various functions such as movement and nutrient absorption. It also provides redundancy in case of injury, allowing for a greater chance of survival. Additionally, segmentation allows for more complex body plans to evolve, leading to increased diversity within animal phyla.

What two features define animal phyla?
Two features that define animal phyla are body plan (organization of tissues and symmetry) and level of complexity (including presence or absence of true tissues, body cavities, and segmentation).
Which characteristics are NOT present in all animal phyla?
Not all animal phyla possess a backbone or true tissues. Additionally, not all animal phyla exhibit bilateral symmetry or segmentation. Some phyla, like sponges, lack specialized organ systems, while others, like cnidarians, have a simple nerve net instead of a centralized nervous system.
How many total phyla?
There are around 35 recognized animal phyla and 11 recognized plant phyla, making a total of approximately 46 phyla across the animal and plant kingdoms.
What is animal phyla?
Animal phyla are major groupings of organisms within the animal kingdom based on shared characteristics like body plan, development, and genetic makeup. There are around 35 recognized animal phyla, ranging from simple organisms like sponges to complex organisms like mammals. Each phylum represents a distinct evolutionary lineage with its own unique traits.
Which of the phyla in kingdom animalia have external segmentation?
Annelida (segmented worms) is the phylum in kingdom Animalia that exhibit external segmentation, with visible body segments along their length. This characteristic segmentation is a defining feature of the group, allowing for greater flexibility and movement.
In the animal phyla why is the segmentation an important development?
Simply, without segmentation, organisms would lack means of movement, complex structure, advanced functions, and organ protection.

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 is sporoza?
An animal-like it is one of the phyla. it does not move
Which of the animal phyla was the first to evolve three germ layers?
The first animal phylum to evolve three germ layers was the Cnidaria. These germ layers are the ectoderm, endoderm, and mesoderm, found in more complex animals for the development of different structures and organs.
How many phylum did we have?
Do you mean, 'How many phyla are there on Earth?' There are more than 20 phyla of bacteria, over 30 phyla of animals and 12 phyla of plants. Fungi and protists, who knows.....? Add up all these phyla, and you can see there is quite a lot.
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.
Which one of the nine major animal phyla is jellyfish?
Cnidaria
