This form, devoted to the vision of fish concentrates on eye pigment on the retina of fish eyes and is based on the work of Denton and Warren (1956), Munz (1964), Munz and McFarland (1973), Ali and Wagner (1975), and Hobson et al. (1981), from which all (409) records so far, pertaining to 371 fish species, were extracted.

The above authors showed that the Sensitivity of a fish eye is maximum at a certain wavelength (in l _max). This value in nm, and its 95% confidence interval (if available) are the essential entries for the table.

A yes/no field allows recording the presence of other pigments (as in Table 3 of Hobson et al. 1981).

A text field for remarks completes this small table.

Users of this table should read the above papers for details on the methods used to estimate l _max.

Updating the VISION table will involve:

• including all species covered in the above-cited papers (by identifying the valid names of several species for which the above authors used now outdated names);

• adding new records from more recent papers, to be identified using the Zoological Record, and the Science Citation Index through its citations to any of the above references; and

• adding information on the relative size of the eyes of each fish species, their activity cycle (diurnal or nocturnal), and depth range, all correlates of
