During frog development, the blastocoel is the first cavity to form. The zygote's cytoplasm is split into a variety of cells, known as blastomeres, during cleavage.
The embryo, which is a ball of cells around a fluid-filled cavity known as a blastocoel by the time cleavage is complete, is known as a blastula. Frog sperm from a male fertilizes a female's eggs, which she lays in the water. The ensuing zygote undergoes embryonic development to become a free-living tadpole, which later undergoes metamorphosis to become an adult frog, for example, by losing its tail due to programmed cell death, or apoptosis. It has been discovered that the initial cleavage furrow is where the blastocoel first formed.
