Slender sunfish

The slender sunfish (Ranzania laevis) is a mola of the family Molidae, the only extant member of the genus Ranzania,[1] found globally in tropical and temperate seas. Its length is up to 1 m (3.3 ft). Several stranding and mass stranding events have occurred on beaches near Albany, Western Australia.[2][3]

The first South Australian specimen was found at Aldinga in 1944.[4] A cast was made from it, and a replica was made, painted and prepared for display at the South Australian museum that year.[5] Several other individuals have stranded in South Australia at Port Willunga, Netley[6] and West Beach with the latter successfully returned live to deeper water.[7]

The body of this fish gives the appearance of the side view of a larger shark (an optical illusion underwater). This is most likely to ward off any would be predators.
