The lifespan of Pseudomonas is generally between 3-5 years; usually, the lifespan of Pseudomonas has a certain relationship with their living environment and feeding methods. Rat life expectancy is extended.

Then let's take a look at the pseudo bog rat living environment. Pseudospermus mainly inhabits the lowlands surrounded by mangroves and lakes and swamps. Pseudo-marsh rat's nests are built on mangrove trees, somewhat like termite mounds. They build nests of leaves and mud that can be as high as 60 cm. Nests usually have only one entrance, but have multiple compartments inside and are connected by passages. Due to the complexity of the passages, their dwellings sometimes overlap.
