Angola
marine fauna data recording form |
|
The
occurrence of marine mammals and turtles off Angola is poorly-known,
and we welcome opportunistic sightings from the public and offshore
personnel which can provide valuable information on the distribution
and seasonality of species. Ketos Ecology maintains a sighting
database of incidental records reported by sports fishermen, rig
workers and coastal observers in Angola. To report a sighting
of a marine mammal/turtle, please download and complete the data
recording form:
