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.
Only recently have we had a glimpse into whale shark reproduction. Like their nurse shark cousins, whale sharks are live bearers. A pregnant female killed in Taiwan was found to have 300 pups inside.It is thought that whale shark babies develop like nurse shark babies inside thin, membranous egg cases which are retained in the mother s uterus.nly recently have we had a glimpse into whale shark reproduction.
