Characteristics

The carapace, or shell, is often adorned with spines or tubercles, providing a rugged appearance. They have a distinctive pair of long, slender antennae that are used for sensory purposes. Allogalathea species also possess a prominent rostrum, a beak-like projection on the front of the carapace.

Environments

Allogalathea species are found in a wide range of marine habitats, from shallow coral reefs to deep-sea environments. They are often associated with rocky substrates, crevices, and seagrass meadows. Some species are known to be commensal with other organisms, such as sea anemones or sponges, utilizing these associations for protection or food.
