Centrolécitos
Isolécitos or oligolécitos are eggs that contain a small amount of yolk uniformly distributed throughout the cytoplasm. They are characteristic of echinoderms and chordates.
Heterolécito or mesolécito are eggs that have about half of the cytoplasmic volume (vegetative pole) occupied by yolk, while the nucleus is located at the opposite pole (animal pole). They are characteristic of annelids, mollusks, amphibians, and some species of fish.
Telolécito or megalécito are eggs in which the amount of yolk is so large that it occupies almost the entire cytoplasm (vegetative pole), while the nucleus occupies a minimal space on the periphery (animal pole or germinal disc). They are characteristic of birds, reptiles, and some species of fish.
Centrolécitos are eggs in which the nucleus is central, surrounded by the cytoplasm. They are characteristic of arthropods, where the yolk occupies the central region.
