A preliminary report on the fine structure of Tripneustes esculentus eggs.
The fine structure of Tripneustes esculentus eggs was studied with the aid of an electron microscope. Cells obtained from this West Indies sea urchin showed cortical granules, mitochondria forming a rosette around lipid granules, endoplasmic reticula, Golgi apparatus and annulated lamellae. These structures appear identical to those seen in eggs of the Atlantic sea urchin: Arbacia punctulata.
