As pointed out- the FACT that these long-lived species shed broken down systems and genetics refutes your statement.

Some do and some don't. Amoebas have a genome many times the size of the human genome. There are bacteria having essentially zero non-coding genetic material. Mitochondria have genetic material that is very resistant to change.

It is simply counterfactual to assert that living things devolve due to entropy.

None of which you mentioned argues that species are not subject to entropy
