Mammalodon probably lived by sucking small animals up from the seafloor

Ancient whale sucked mud for food

An ancient "dwarf" whale appears to have fed by sucking small animals out of the seafloor mud with its short snout and tongue, experts say.

Researchers say the 25 million-year-old fossil is related to today's blue whales - the largest animals on Earth.

The ancient animal's mud slurping may have been a precursor to the filter feeding seen in modern baleen whales.

These whales strain huge quantities of tiny marine animals through specialised "combs" which take the place of teeth.

The research is published in the Zoological Journal of the Linnean Society.

The fossilised remains of the primitive baleen whale Mammalodon colliveri were discovered near Torquay, in Victoria, Australia.
