Treehugger report on their site of a strange little experiment whereby a Brazilian aquarium has made a window in a shark eggcase to observe its stages of foetal development. Throughout the video you can see the tiny bamboo shark writhing around still attached to its embryo. It is rumoured that British shark specialists are to attempt a similar experiment with an endemic catshark species but are so far still trying to develop an eggcase window with double glazing.
Slightly more serious and potentially significant for the conservation success of many shark species is a report in the Journal of the National Cancer Institute that reports that shark cartilage has no positive effects to sufferers of lung cancer. The notion that eating shark cartilage has health benefits is often cited by the pro fin soup culture and so this new report, the only one of its kind, will hopefully dispell the myth that shark cartilage has any health benefit at all and hopefully the demands for sharks fin will fade a little.
