Although vandelliine catfishes feed exclusively on blood as adults, the recently discovered juveniles are apparently predators on small aquatic invetebrates, as is the case for most other trichomycterids from other subfamilies--and their morphology reflects this. The structure of the mouth of juvenile vandelliines resembles that of non-parasitic trichomycterids, but juvenile vandelliines undergo a metamorphosis during which their mouth structure transforms to the highly modified adult blood-feeding morphology.
