If you’ve managed to go to the Whales|Tohorā exhibition here at Te Papa then you’ll have come across the pieces of baleen.
Some whales have teeth – others have baleen. Baleen sort of looks like bristley paintbrushes hanging down either side in a whale’s mouth. It acts like a big sieve or tea strainer. Baleen whales scoop tiny organisms like krill and copepods in mouthfuls along with sea water. They force the sea water out of their mouths through the baleen leaving the prey behind.
The whales then use a combination of their tongues, sucking action and possibly some rinsing with sea water to dislodge the prey from the baleen (its hairy on the inside and the prey gets caught) before swallowing.
The colouration of the baleen depends on the type of whale it is – the blue whale’s is almost black.
Our pygmy right whale’s baleen is creamy white on the inside, dark grey on the outside with a stripe of creamy white along the top. Its beautiful.

Will the baleen stay this colour over time? Most examples I’ve seen in museums have been grayish but I’ve never seen one from a pygmy whale. Also, any idea how old this animal is?

Hi Lynne
I’ve just checked you out seeing as your last name coincided with Dr Cath Kemper’s – she’s all good!
Prof Fordyce thinks that the baleen will retain its colour over time, probably fading a bit. Its gorgeous isn’t it!
As for age – they say that he’s under six months.
