Of course that organism changes over the course of its life (I have made this same point many times whenever this same old issue comes up again). But when I saw it, I saw it as the collection of atoms that it was when the light hit my retina.

Responding to both Stephen (who should know better, having a background
in metaphysics if not indeed in shipbuilding) and Rich.
As part of a famous quote, Darwin used the phrase "...which, from its
familiarity, does not always sufficiently strike us...". In his specific
case, he was referring to the taxonomic hierarchy, but I find the
statement generally useful in the study of biology--we often falsely
assume that familiarity equals understanding.
Senses can lie. Preconceptions can mislead. I can see a mountain, and
even attempt or succeed to climb it. I can't see the clone for the
trees. I've never seen a virus. I knew a blind man who never saw an
elephant. I've never seen a photon, nor an atom, but I have seen a
retina. I take pleasure in looking at optical illusions. I've seen a mirage.
All of this is immaterial. One either applies the same level of
scientific scrutiny to "individual" as one applies to "mountain" or
"photon", or else one leaves the world of inference and enters the world
of belief. There's nothing wrong with belief (I, for one, do it all the
time), but it's not science, and can never successfully masquerade as
science, no matter how many hands are waved.
