The most striking feature of Guildfordia aculeata is its large, globular shell adorned with prominent spines or tubercles.

The species thrives at moderate depths, typically from 20 to 200 meters, although its specific range may vary depending on local environmental conditions.

[5] As a herbivorous marine snail, Guildfordia aculeata feeds on algae and biofilm that grow on rocks and corals.

However, like many marine species, it may face threats from habitat destruction, such as coral reef degradation, pollution, and the effects of climate change.

Sustainable management and conservation of coral reef ecosystems are vital to ensuring the continued survival of species like Guildfordia aculeata.
