baleen

By way of comparison, previous estimates had found that all baleen whales off the Pacific coast of North America ate 2 million metric tons of seafood every year.

Savoca and his colleagues “measured all the things you need to measure to get an accurate estimate of consumption,” for baleen whales, she says.

Songs resonated with people as something that individuals did, and was not just some feature of a species like their baleen or the shape of their flippers.

That baleen is made of keratin — the same stuff as hair — and lets the whale filter krill and other small invertebrates from the water to eat.

Earlier sea ice melting and warmer surface water means more krill and other food for these baleen feeders.

The ulna and radius in the rorquals are also comparatively longer than in the baleen whales.

In this respect it differs much from the baleen whales, which have a narrow gullet.

The baleen is then cut out, and the carcase abandoned to the sharks, killer whales, and sea birds.

Many of them grow to enormous size, far exceeding any of the baleen whales.

So, also, the baleen of the whale and the teeth of the land mammalia are different organs.
