stingray x-ray

Another in the occasional series of rather lovely biological images: an x-ray of a stingray (Heliotrygon sp.)


(from NatGeo, via Pharyngula)

The genus name means ‘sun stingray’, a name that was given for the way that the cartilage fibres that support its body (like sharks, stingrays have a skeleton that’s based on cartilage, unlike the hard, ossified skeleton of (adult) humans). 

Another cool thing about this image is that you can clearly see that this stingray is, in fact, stingless!
