The carpet sharks or wobbegongs (Orectolobidae) are a family of sharks in the order of the nurse shark-like (Orectolobiformes).

Wobbegongs are strongly flattened dorsoventrally and mostly patterned. They wear membranous rags and barbels around their mouths . The nostril is connected to the mouth by nasal pits. Their young give birth to these sharks alive. They inhabit the shallow water areas of warm, mostly tropical waters and bury themselves there in the silty seabed.

Genera and species

Carpet sharks comprise three genera - the most species-rich are the real carpet sharks ( Orectolobus ) with the common carpet shark or wobbegong ( Orectolobus maculatus ) and nine other species. The genre is currently in an intensive systematic process, so that statements about the internal relationships cannot be made. With the western carpet shark ( O. hutchinsi ) described scientifically in 2006 , the O. floridus O. reticulatus and O. parvimaculatus described in 2008 as well as the Orectolobus leptolineatus described in 2010, four new species have been described in recent years, described during the 1840 and as a synonym for O. halei regarded ornamented carpet shark again in 2006 as a separate species.

The other genera are Eucrossorinus with only one species ( Eucrossorinus dasypogon ) and Sutorectus also with only one species ( Sutorectus tentaculatus ).

Hunting behavior

Carpet sharks primarily eat invertebrates and bottom fish. In individual cases it happens that a carpet shark eats other sharks such as a bamboo shark .
