| Notes: |
Highly developed adhesive structures are characteristic of the eggs of Odonthestes bonariensis. At spawning each egg is connected to the other ones by four to six filaments. These are extroverted only in mature eggs, about 4–5 mm long and 10μm thick, starting from coneshaped bases at the egg's surface. Histologically, no filaments are detectable during the primary growth phase of the oocytes. At the lipidic vesicle stage, rounded eosinophilic filaments appear at the cell's surface. During the following stages they increase in volume and length, running along the whole oocyte, and lose their eosinophily. The filaments are beneath the follicular cells; according to preliminary TEM observations, they derive from the zona radiata. When the oocyte is mature, the theca externa disintegrates, freeing the filaments. These rather conspicuous and complex structures are markedly different from the adhesive egg fibrils observed in other teleosts.
