Organisms with external fertilization exhibit high synchrony between sexes and release numerous gametes into water to enhance chances of syngamy, as seen in bony fishes and frogs. However, their offspring are highly vulnerable to predators.
Gli organismi che esibiscono fecondazione esterna mostrano una grande sincronia tra i sessi e rilasciano un gran numero di gameti nel mezzo circostante (acqua) per aumentare le possibilità di singamia. Ciò accade nei pesci ossei e nelle rane dove vengono prodotti un gran numero di prole. Un grave svantaggio è che la prole è estremamente vulnerabile ai predatori che minacciano la loro sopravvivenza nell'età adulta.
| Text | Organisms exhibiting external fertilisation show great synchrony between the sexes and release a large number of gametes into the surrounding medium (water) in order to enhance the chances of syngamy. This happens in the bony fishes and frogs where a large number of offspring are produced. A major disadvantage is that the offspring are extremely vulnerable to predators threatening their survival up to adulthood. |
