@Bactrian Deer I came in touch with another Zoochatter (who uses these pictures in his own productions), and he sent me some vector images.
Please send me a private message for more informations.
@Bactrian Deer@Haliaeetus in case you're also looking for more specific (and high quality) images there's also PhyloPic, a site that has silhouettes for a wide range of life forms! PhyloPic
