Why aquatic animals release hundred of eggs and millions of sperms?

Answer»

They are protandric; during their first year they SPAWN as males by releasing sperminto the water. ... An increase in watertemperature prompts a few OYSTERS to spawn. This TRIGGERS spawning in the rest, clouding the water with MILLIONS of eggsand sperm. A single female oyster canproduce up to 100 million eggs annually
