Tooth Shape:

Grey Nurse have long slender teeth for grasping prey 
such as pelagic fish.





Reproduction:

Ovoviviparous
Developing young are enclosed in egg cases within each 
uterus of the female. They hatch from the egg cases at 
around 55mm in length and then eat any unfertilised eggs 
and even their brothers and sisters. This is known as 
intra-uterine cannibalism. After around 9-12 months, 
2 young are born, one from each uterus.




Interesting Facts:

Grey Nurse sharks can swallow air at the surface and hold it in their stomachs. This provides buoyancy and enables the shark to hang almost motionless above the sea floor.

Grey Nurse sharks appear fearsome due to their protruding teeth, however they eat mostly small to medium fishes, squid and lobster.

They are harmless to humans.
