Agnatha are ancient jawless fish that include lampreys and hagfish. They are also probably the earliest vertebrates and have ectoderm.
The endoderm and ectoderm
The three germ layers are the endoderm, mesoderm, and ectoderm. Endoderm gives rise to the innermost tissues and organs, mesoderm forms the middle tissues and organs, and ectoderm becomes the outermost tissues and structures of an organism.
They have two layers the endoderm and ectoderm.
The three primary germ layers that form during the embryonic development of mollusks are the ectoderm, mesoderm, and endoderm. The ectoderm gives rise to the skin and nervous system, the mesoderm forms muscles and internal organs, while the endoderm forms the digestive tract.
The three main types of cells that can form during differentiation are endoderm, mesoderm, and ectoderm. Endoderm gives rise to internal organs such as the gastrointestinal tract. Mesoderm forms tissues like muscle and bone. Ectoderm develops into the nervous system and skin.
Endoderm
The three germ layers of a gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). These layers give rise to different tissues and organs in the developing embryo through a process known as gastrulation.

The endoderm and ectoderm
There are three layers: ectoderm, mesoderm, and endoderm.
The two tissue layers of diploblastic organisms are the ectoderm and endoderm. Ectoderm is the outermost layer responsible for covering and protection, while endoderm is the innermost layer involved in digestion and nutrient absorption.
ectoderm is the young epidermis, same with endoderm, it is the young gastrodermis.
The three germ layers are the endoderm, mesoderm, and ectoderm. Endoderm gives rise to the innermost tissues and organs, mesoderm forms the middle tissues and organs, and ectoderm becomes the outermost tissues and structures of an organism.
Ectoderm, endoderm, and mesoderm can produce epithelial tissues
They have two layers the endoderm and ectoderm.
