genus Scylla (2022) directly explores the relationship between Man and Beast, breaching themes of ecology and ultimately essentialism of other sentient beings beyond the human realm.

Man’s arrival on the planet has introduced an unprecedented super-predator onto Earth’s ecosystem, resulting in anthro-oriented damage to different species of animals. Siew examines these changes, such as genetic modification or pollution-induced mutation, and identifies elements of Remi Astruc’s grotesque, understanding humankind’s encroachment into the beastial "other" as fundamentally existential. This is because our compounding actions as a species holes power over the reality of the biologies around us.

This is especially poignant in Siew’s selection of the crab as a focus. In palaeontology, crabs supposedly possess an ideal blueprint for crustaceans. This causes many non-crab species to eventually evolve into crab-like animals, in the theorised process of carcinisation. By hyperbolising morphological mutation and reverse carcinisation in his work, Siew insists on a speculative reality where mankind has effected change onto nature so great that even the biological tank that is the crab has to change its shape and way of life.

In Mahayana Buddhism, man and beast are both sentient creatures bound to Samsara. In addition to the philosophical grotesqueness of the chimaera and the mutant, Siew evokes spiritual grotesqueness. The devastation man affects onto the Tiryag (animal) realm resounds greatly into human consciousness, as we are thought that each animal has the potential to be reborn as a human, and each of us have the potential to be reborn as the tortured beast.
