The species reference

A page for each species in the logbook.

Each species page records where the animal is seen, at what depth, and how hard it is to find at each destination. The list is the same one the logbook uses on the boat.

The records cover many dives and can be used to choose a destination or a time of year.

How ratings work

Ratings are counts of logged dives.

A rating counts how many logged dives looked for one animal at one place, and how many of them found it.

None of the ratings are counts yet. All 16,955 of them are editorial estimates, and every page says so. An estimate is replaced by a count when enough dives have been logged for that species at that location.

Ratings are updated when divers log their dives.
