Leopold and son Rudolf Blaschka were 19th-century glass blowers who somehow produced perfect re-creations of sea life.
Their collection of lifelike glass sea creatures were long-forgotten, until marine biologist Drew Harvell uncovered them in a New York warehouse in the late 1980s.

Now, she's attempting to photograph the real-life counterparts to the glass models, but many of the species shaped in glass during the Blaschkas' time no longer exist.
Here's a look at some of those magnificent specimens crafted by the Blaschkas.
