Gasteracantha has a complex taxonomic history, and many questions of species limits and distribution and generic interrelationships remain unanswered. Furthermore, challenges include the variability within individual Gasteracantha species (e.g., color polymorphism and variable length and shape of spines), a lack of male specimens and descriptions for many species, missing or damaged type ...
The spiny orb-weaving spiders in the genera Gasteracantha and Micrathena look like plant seeds or thorns hanging in their orb-webs. Some species of Gasteracantha have very long, horn-like spines protruding from their abdomens. One feature of the webs of some orb-weavers is the stabilimentum, a crisscross band of silk through the center of the web.

The Australian garden orb weaver spider (Hortophora transmarina) is a very common species of spider with many variants in size, shape, and colour across the coastal and northern regions of Australia.
Gasteracantha fornicata is a small spider that displays multiple morphs in size and colour. It has exoskeletal spines across its dorsal side. The wide cephalothorax structure of Gasteracantha may prevent it from being as mobile compared to spiders of similar size. [4] Males are typically two millimeters while females grow up to twelve millimeters.
