Tiger salamander

Post by sujin007 on Wed Dec 05, 2012 9:21 am

As do most amphibians, Tiger Salamanders start their lives as aquatic larvae or “tadpoles”. But they are unusual because their eggs can develop into two different kinds of tadpole.

These are the so called “normal morph” and the “cannibal morph”. The cannibal morph has a larger head, bigger mouth and more developed teeth, and is larger than its normal siblings..

Usually, the cannibal morph appears only when the pond where the eggs were laid starts to dry up, or when food is scarce.

They eat smaller tadpoles and develop more quickly as a result, metamorphosing earlier into adults. But if food is too scarce, they don’t mind gulping a few brothers or sisters, hence their inclusion in this list.

This clever, if brutal survival strategy allows Tiger Salamanders to successfully breed even when the circumstances are not the most idoneous.

The most amazing thing about these cannibalistic tiger salamanders is that they seem to recognize their siblings and will usually avoid killing them..

Instead, they go after unrelated tadpoles born in the same pond. They can even recognize their first cousins and avoid eating them as well!!!!!
