Abstract english

An action spectrum for photosensitivity in sponge larvae

published by Leys et al. [J. Comp. Physiol., A, 2002, 188,

199–202] was interpreted by the authors as being due to a

combination of light absorption by flavin or carotenoid in

the blue region, and another pigment such as pterin in the

long-wavelength region. Here we show here that their action

spectrum closely matches the absorption spectrum of reduced

cytochrome c oxidase that is present in sponges, and compare

with other photoreactions which are thought to be due to this

chromoprotein.
