Why be a cannibal? The benefits to cane toad, Rhinella marina  [= Bufo marinus ], tadpoles of consuming conspecific eggs Costs of eating conspecific eggs are likely to be low. The toxins of cane toads pose no danger to cannibal conspecifics, even though the same toxins are deadly to tadpoles of Australian frogs (Crossland and Alford, 1998, Crossland and Azevedo-Ramos, 1999, Crossland et al., 2008 and Crossland and Shine, 2010).1) Toxin transfer. The amount and diversity of toxins (bufadienolides) decrease from the egg stage through larval development in cane toads, such that late-stage tadpoles and metamorphs have less effective chemical defences than earlier tadpoles or (especially) eggs (Hayes et al. 2009).
