Phylum Platyhelminthes have three tissue layers: ectoderm, mesoderm, and endoderm.
There are thousands of species of cold-blooded animals, including reptiles such as snakes, lizards, and turtles, as well as amphibians like frogs and salamanders, and fish. Cold-blooded animals rely on their environment to regulate their body temperature, as opposed to warm-blooded animals that can internally regulate their temperature.
Toads belong to the Bufonidae family, which includes various species such as the American toad (Anaxyrus americanus), European toad (Bufo bufo), and cane toad (Rhinella marina). Each species has distinct characteristics and habitats.
There are approximately 900,000 arthropod species within the animal kingdom (insects and spiders), 100,000 species of roundworms and mollusks, and fewer than 50,000 species of vertebrates (20,000 fish, 8,700 birds, 6,000 reptiles, 2,500 amphibians, and 4,500 mammals). In total, that makes approximately 1,050,000 species within the animal kingdom.
There are approximately 65,000 species in the Chordata phylum, which includes vertebrates like mammals, birds, reptiles, amphibians, and fish, as well as some invertebrate species like tunicates and lancelets.
how many tissue layers do the phylum arthropoda have
There are three layers of embryonic tissue present in the pig. These layers are called the ectoderm, mesoderm and the endoderm.

Phylum Platyhelminthes have three tissue layers: ectoderm, mesoderm, and endoderm.

Four layers of tissue form the walls of the digestive tract. These layers are called mucosa, submucosa, muscularis externa and adventitia.
Skin consists of three layers of tissue.
Do you mean how many species, because I don't think anyone can organize a census to ask all the adult amphibians how many children they have.
There is only a single layer of cells in onion tissue. However, sometimes the tissue can fold over itself and appear to have two layers.
