TEHRAN, Nov 23_Mothering poison frog in Madagascar helps scientists study the maternal brain
TEHRAN, Young Journalists Club(YJC)_At least two species, including Madagascar's climbing mantella, a poison frog species, are much more nurturing and attentive than the average frog mom. Both the climbing mantella and Ecuador's little devil frog lay just a few eggs in pools of water that collect in cupped leaves. The moms sit next to their offspring and feed the growing tadpoles' unfertilized eggs until they're big enough to venture off on their own.
New research, published this week in the journal Current Biology, suggests the extra motherly attention helps the young frogs develop potent chemical defenses.
When scientists tested the unfertilized eggs being fed to the newborn climbing mantellas, they found surprisingly high levels of the poison.
