The Case of the disappearing axolotls



At the beginning of the summer holidays we had 25 baby axolotls but during the holidays they started disappearing. Finally there were only 7 left. Strangely one baby axolotl was twice as big as the others that were born the same time as him!
How could this be?
We decided to observe closely and
this is what we saw -can you see the grey tail sticking out of the axolotl's mouth?
This is the fat axolotl gobbling up one of his brothers or sisters. We have named him Chompa!
