Lipoprotein crystals in the yolk platelet of a teleost, Pelvicachromis pulcher (Cichlidae).
Yolk-platelt crystals in the oocytes of the teleost Pelvicachromis pulcher (Cichlidae) were shown, using electron diffraction and tilting of thin-sectioned specimens, to possess an orthorhombic lattice with unit-cells sides a = 8.3 nm, b = 16.6 nm and c = 18.0 nm. They thus closely resemble the crystals known for a newt (Triturus sp.) and a frog (Xenopus laevis).
