Amphibians have been consumed as an alternative protein source all around the world due
to their delicacy. The skin of edible amphibians, particularly frogs and giant salamanders,
always goes to waste without further utilization. However, these wastes can be utilized to
extract protein and bioactive peptides (BPs). Various BPs have been extracted and reported
for numerous biological activities such as antioxidant, antimicrobial, anticancer, antidiabetic,
etc. The main BPs identified were brevinins, bombesins, dermaseptins, esculentins …
