If the runt of the litter is in anyway sick or injured it is possible that the adult females will abandon it, leaving it to die, yes. Chances are that if the runt has been torn apart as (grusome as it may be) it was already dead or it was accidently killed when to females were fighting over who would care for it.
Not always, but it's very likely. Some females kill males ;)
the female praying mantis is famous for eating the male after mating that's life
If you try to keep a male and female (or females) in the same tank permanently, the outcome is always going to be seriously injured or dead females. You cannot keep males with females. Under very carefully controlled circumstances during breeding the male will not kill the female (he will usually nip at her, but not seriously harm her.) But male and female in same tank = dead female.
People do kill members of other ethnic groups, and members of ethnic groups also kill members of their own ethnic groups.
The female always wants to be superior but the male dog wont let her becasue the male wants to be the PACK leader
You cant the male would kill the female unless you have already a female then the female would kill the male
no it will kill another male for domanancy Yes, the male will most likely kill the female. This is not always true, though. When mating they will be vicous (in most cases) but not kill each other. Any other time it is not ideal to stick a male and female betta together. -Raz
no because they will fight and kill each other..................sorry;/
No. Two totally different species. In fact, the gerbil will kill the mouse. They shouldn't be housed together.
The Jews
no
Any other Betta can kill a female. Bettas are so agressive that they will even kill their babies if they wanter to. Also, larger predators can kill.
