Re: NFC: Re: Fishy Behaviour
A possibility that exists in some breeding styles is the
consideration of parental investment. Somehow, the parent may
know which eggs are not doing so hot or will most likely not
survive. They could eat these and concentrate on rearing the
healthy ones. The thinking may be better a few definite survivors
than zillions of goners. This is what lots of terrestrial vertebrates
do, though not necessarily by eating the young. Of course, this
wouldn't apply to those that abandon the fry to survive for
themselves...
