Despite being a common and easily studied shark, found in good numbers around most of Australia’s enormous coastline, as recently as March 2008 two new wobbegong species were discovered, bringing the total known species to nine. The two newly described species were at first thought to be juveniles of known species. One, the dwarf spotted wobbegong (Orectolobus parvimaculatus) grows to about one metre, far smaller than the two-metre spotted wobbegong.

Less rigorous on a scientific level, but no less interesting, is this observation from Julian Rocks, a popular dive spot located off Byron Bay:

Crayfish form commensal relationships with wobbegongs. Wobbegongs eat octopus, and octopus eat crayfish. By living in close proximity to the wobbegong, the crayfish serves the wobbegong as bait and in turn receives protection.57
