Sousa taxonomy is based largely on small sample sizes for most populations. The several different nominal species are distinguished on several primary characters. Characters include tooth counts; number of vertebrae; form of the dorsal fin base and especially colour patterns (G. Ross, pers. comm.). G. Ross suggests that all Sousa from S. Africa to China and Australia are one species, and probably S. teuszii is also conspecific. However, "we will have a better idea when we can include more definitive genetic work" (G. Ross, pers. comm.). For the purpose of this review, I followed Rice (1998) who separates the Genus Sousa into three species.
According to Carwardine (1995) this species seems to be particularly common in southern Senegal and northwestern Mauritania.
There are signs of a probable north-south migration for this species and there is a potential exchange of individuals between known population or subpopulation distribution centres (from north to south): Dakhla Bay, Banc d'Arguin, Langue de Barbarie, Sine Saloum delta, NW bank of the Gambia River outer estuary and Guinea-Bissau archipelago (van Waerebeek et el. 2000).
all the way getting out from the village this is the kind of landscape you have for at least 150 km.
offices in Nouamghar north entrance.
you have either to give your entrance ticket to the guard or to buy one.
people here seem to do the same to fish as other people in other countries do. The sun is the same for everyone...
try to enjoy the beach once you have to wait until the tide goes down. For my experience I tell you that can be much more important to enjoy the view, the birds, the dolphins than being on the beach talking to people usualy tourist or a couple of senegalese youngters trying to get something out of you.
Favorite thing: inside the national park yard. The guard here asked us for some simple requests like clothes shoes or something useful for his children. My friend gave him some shoes.
Favorite thing: The policeman I found here at the time was quite nice. I asked him 3 times for his name and he went on telling he had no name. I'm nameless he told.
