Fig. 5 in Reproduction and spawning behavior in the frog, Engystomops pustulatus (Shreve 1941)

Fig. 5. Relationship (in log space) for body and testis mass among 11 species of Leptodactylinae frogs. Except for Engystomops pustulatus, data is from Prado and Haddad (2003). Open circles indicate species on which multimale spawning has been reported. Note that E. pustulatus, in which multi-male spawning apparently occurs, also has larger testis than other Leptodactylinae.
