Introduction. Baastrup's sign, also referred to as âkissing spinesâ, is a common disorder of the vertebral column characterized by close approximation and contact of the spinous processes of two adjacent vertebrae, resulting in the formation of a new joint between them (Baastrup, 1936 and Sartoris et al., 1985)..

The most likely theory though is that the name comes from the Old English word for sea-floor shark: hurse. Nurse sharks are slow-moving bottom-dwellers and are, for the most part, harmless to humans. However, they can be hugeâup to 14 feet (4.3 meters)âand have very strong jaws filled with thousands of tiny, serrated teeth, and will bite defensively if stepped on or bothered by divers who assume theyâre docile.
Nurse sharks eat Krill, small bony fish, crabs and they live on the sea floor, (so do nurse sharks) Nurse sharks don't eat stingrays and are harmless to humans, but not to smaller sea animals. This answer might not be correct because i went on Wikipedia and it did say things like they do eat stingrays and so on so guys before listening to this guy go on wiki
