The catshark is a nocturnal shark, rarely
seen by divers. They lay their eggs on
the ocean fl oor, using the coiled tendrils
at the end of the egg case to attach it to
fi xed objects. The developing shark lives
off the yolk sac but once born the shark
must fend for itself. There are 21 species
of catsharks found along Western
Australia’s coast, so it is hard to
determine what species (or type)
of catshark the egg case has
come from.
