There was an error published in J. Exp. Biol. 211(19), iv.

In this Outside JEB article, the first author of the following reference was incorrectly referred to as Yoshi Watanabe:

Watanabe, Y., Wei, Q., Yang, D., Chen, X., Du, H., Yang, J., Sato, K.,Naito, Y. and Miyazaki, N. (2008). Swimming behavior in relation to buoyancy in an open swimbladder fish, the Chinese sturgeon. J. Zool.275, 381-390.

This should have read Yuuki Watanabe.

We apologise to our readers and, in particular, Dr Watanabe for this error.
