Certainly possible my friend; however, assuming that you are giving due 
consideration to the “evolutionary time” that might lead to a set of 
haplotype permutations and combinations that may result in selection of so 
called fittest ones!

On a more serious note, longevity doesn't just depend upon an organism's 
ablity to camouflage! It depende on a myriad variables that are resultant 
of various environmental and genomic factors, for instance, ROS-mediated 
accumulation of mutations in mitochondrial DNA, which may lead to several 
late-onset degenerative disorders. Reactive oxygen species are one of the 
major factors involved in cellular wear and tear. Further, more age also 
means more exposue to various environmental mutagenic or carcinogenic 
radiations or substances, for instance, solar UV radiations, for organisms 
living in a natural setting. All these factors make this hypothetical 
situation difficult to realize.

I hope that answers your query. Feel free to ask if you have any further 
queries.

Regards,
Tarun Gupta
