Behold the cartilaginous skeleton of a sand tiger shark (Carcharias taurus)!! The Vancouver Aquarium has a whole exhibit on the inner workings of marine creatures, from skeletons to plastinated specimens!
Wow! Genetics can be a crazy force of nature. I had to share this found photo with you guys!
“Frog with eyes in its mouth as a result of macromutation. A macromutation is a mutation that has made a significant impact on an organism, caused by a change in a regulatory gene that’s responsible for the expression of an array of structural genes.
It’s been suggested that the cause of the mutation was the result of a parasitic infection by a trematode worm (Ribeiroia ondatrae). Trematode infections have reportedly been linked to an increasing number of amphibian limb mutations, particularly missing, malformed, and extra hind legs.”
