[1] The species is named after the aquarium supply company Dennerle, which supported one of the describing authors' (Christian Lukhaup) study in Java.

It is common to find dennerle hiding in burrows in areas composed of muddy creek valleys, with rocks and dense vegetation.

[4] The high endemism of species within the Geosesarma genus, means there is not a great amount of geographic distribution.

Members of the Geosesarma genus commonly produce large eggs, averaging between 1.2 and 1.8 mm in diameter.

[8] Members of Geosesarma become sexually mature around 6 months of age, with breeding consisting of the male mounting the female to fertilize eggs.

[3] This species has direct development offspring: fully formed miniature versions of the adults hatch from the eggs.

They are often mistaken for aquatic crabs and kept in unsuitable conditions with excessive amounts of water, which leads to shortened life spans.

As these species live in the ground, primarily in burrows, soil is vital for their well-being, stress reduction and breeding.

Both of which can easily be met with a small water volume, enough to cover their entire body completely will suffice.
