Schemes of Xenopus laevis tadpoles

Schemes of Xenopus laevis tadpoles at developmental stage 50 and 54 in 'Individual images of Xenopus laevis tadpoles' (see references). These drawings are low detail pictograms and lack characteristics for identifying a particular developmental stage; they are therefore best used for illustrations that require Xenopus tadpole icons. The file includes several versions of each sketch, with various amounts of details.
