Sharks, skates and rays collectively the elasmobranchs come in a wide variety of shapes and sizes, with around a thousand species known to science. Many of these are on the menu of other animals, often other sharks or rays. It may come as something of a surprise that even the most iconic of shark species, the formidable great white Carcharodon carcharias, is not immune to predation. Elasmobranchs are subject to the dangers of predation from their first moments in this world. Several fascinating papers by David Cox and Thomas Koob at Shriners Hospital for Children in Florida during the mid-to-late s described predation on elasmobranch eggs. In one particular paper to the journal Environmental Biology of Fishes in , Cox and Koob presented data on ten species of shark and ray whose eggs had drill holes from gastropods molluscs, such as snails, limpets, whelks and slugs. It seems that these molluscs use their drill-like radula tongue to bore into the eggcase and feed on the energy-rich yolk. In a paper, Cox, Koob and Paddy Walker reported on boreholes found in the eggcases of thorny skates Amblyraja radiata trawled off the Danish coast during June of
