learn only 3 things about them ... They are fierce predators!
Some can bore a hole through the prey's shell. It takes them a
long time to get at their prey. Don't lay large collections of
egg capsules on the rocks. Where seen? You will almost be
certain to meet this ferocious predator on our rocky shores!
Drills are commonly seen on boulders and rocks, including man-
made structures such as breakwaters and jetty Features: Among
the common drill species on our shores are Rock-shell (Thais
sp.), Drupes (Morula sp.) and Murex (Chicoreus sp.). Drills
usually have thick shells and a thick operculum made of a horn-
like material. Those with complicated spines on their shells
usually move by holding their shells above the surface as they
move along the surface. Bored to Death: Drills that live on the
rocks are predatory molluscs that bore into other shelled
creatures, To bore a hole through the victim's shell, a drilling
snail softens the shell with a weak acid secreted by a special
gland on the underside of its foot.
