Huge iceberg threatens penguins

The iceberg

A huge iceberg which broke off the Antarctic could affect penguins and seals, scientists have warned.

When the iceberg broke off in early February, it changed the amount of open water in the area, which could change the types of food available there.

This means emperor penguins and seals will have to travel further to find something to eat.

The iceberg is 78km long - that's the same as 8,125 London buses! It broke off when it was hit by another iceberg.

The new iceberg has been named the Mertz Glacier by scientists.
