All clams, i do belive, start out as males and half of them turn into female or become both in there life spam. Researchers at the Marine Biological Association in Plymouth examined clams in estuaries from Southampton to the Severn and found that males at 17 of 23 sites suffered a condition called "intersex", where their testes contain both sperm and eggs. In some cases the male sexual organs contained thousands of eggs and up to 60% of clams were affected.
All clams start out as males first. Some decide to become females at some point in their lives.
Clams can be either male, female or both (hermaphroditic) depending on what stage it is on during its life cycle. For example, the hard clam (quahog) begins its life cycle as a male, then later on may become a female. The various kinds of cockles found around the world are all hermaphroditic as adults. There is no way to really tell a male from a female clam. Fortunately, either sex tastes equally good, which for most people is probably all that matters in this regard.

This is the theory because all femle ova have female chromosomes.. Sperm have male and female chromosomes. If the sperm containing female chromosomes then nothing changes during fertilization. If male chromosomes, then changes take place to cause the cells to produce a male. There is scientific theory that this may be a cause of homosexuality in that the changes do not occur as expected. But this is only theory. --- They don't necessariy start as female, but they do have female organs. It is the presence of chemicals (due to Y chromosome) that forms the male organs from the female organs later on.
It depends on the clam species. Apparently, some start out as little swimming larvae, and secrete a hard shell during one of their larval stages, or when they go through metamorphosis. Other species are released from the parent's mantle cavity as fully developed little clams.
