What is animal phyla?

Phyla is plural for Phylum. It is used in animal taxonomy and is the category between kingdom and class. Animals in the same phylum have the same degree of developmental similarity. There is a total of 36 animal phyla that all animals fall under and the largest phylum is Arthropoda.


What characteristics do all mollusks share that separate this phylum from other phyla in the kingdom animalia?

All mollusks possess a soft body covered by a hard shell, a muscular foot for movement, and a mantle that secretes the shell. These characteristics distinguish mollusks from other phyla in the animal kingdom.


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.


All of animal phyla on Earth today evolved during what period?

All animal phyla on Earth today evolved during the Cambrian Explosion, which occurred around 541 million years ago. This period marked a rapid diversification of multicellular organisms and the emergence of most major animal groups that exist today.


Where do most of the phyla of the animal kingdom of animals occur?

Most animal phyla occur in marine environments, particularly in the oceans. This is because the marine environment offers a wide range of habitats that can support diverse forms of life and provide opportunities for evolutionary divergence.

Why are all animals in the animal kingdom separated into vertebrates and invertebrates?

They're not, really. The animal kingdom is divided into multiple phyla, such as arthropods, molluscs and roundworms. Vertebrates are only one of these phyla. They're classified according to their traits and evolutionary history, and grouped according to their relation to one another.

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.
