A newborn Mazu
Early in February 2010…[after killing the adult mother of a Congo Clawless otter pup, a hunter, named Mundweni, brought the newborn pup to two missionaries serving in the Democratic Republic of Congo (DRC), Africa.]

Glen and Rita Chapman are missionaries who have both lived most of their lives serving in the Congo. Their mission station is a small pastoral training center called Kikongo. About 170 kilometers east of Kinshasa, the capital city, their idyllic home village lies on the bank of the Wamba River (a tributary to the Kwango River) in Bandundu Province, DRC. Rita has a special gift for successfully raising wild orphans. So, Mundweni presented Rita with the newest addition to her menagerie.
 
The Congo Clawless Otter (Aonyx congicus) range corresponds to the Congo river basin. It is one of the least known otter species in the world. It has a patchy distribution across its range of occurrence and a very low density of occupation where it is found. Within their previous range, their population numbers have been reduced and they have been extirpated from areas where they may have previously been assumed to occur. There is a desperate need for conservation action and research.
Threats to Survival:  
  • the escalating demand for bush meat and skins
  • habitat loss and degradation
  • steep decline in fish populations due to overfishing by humans with improved technology and nylon fishing nets
  • pressure from development of hydro-electric power projects
  • under-representation of otter habitat in protected areas
  • pollution and deterioration of water quality resulting from large scale deforestation throughout their range
  • growing proliferation of weapons and munitions such that now otters can be shot from pirogues and river banks
  • dramatic depletion of other species (such as the hippo) who play an integral role in the food chain on which otters depend and contribute to the aquatic-ecosystem functioning that supports otter food supplies.
The Congo Clawless Otter is the most terrestrial otter species in the world and is therefore much more vulnerable to snares set on land. They are not protected by traditional taboos across their range. Some of these threats can be considered major, but more importantly is the dramatic combined effect of threats on otter populations.
 
Today (as of late 2010), the little pup is now known around the world as "Mazu" in deference to her persistent vocalizations recognized in the world of otter husbandry as the "nursing hum." Mazu means "noise" in the tribal Kikongo language. Mazu has united the interests of people around the world and in her home village. Locally and abroad Mazu has become a symbol of Congolese natural heritage and a global treasure. Through the efforts of the International Otter Survival Fund (IOSF), Mazu has been introduced to the world and on this global stage has become an unparalleled ambassador for African Otter Conservation.
 
Mazu helping to teach future conservationists
The Future for Mazu: it will be inappropriate to release her back into the wild. Congolese do not have experience distinguishing between wild animals and tamed wild animals when they are hunting. So, with the support of a group of caring individuals and organizations, Glen will be providing a safe and stimulating enclosure to meet Mazu's growing needs, Rita will continue to provide the nurturing and sensitive care under which Mazu thrives, the local community will reap the benefits of global attention and Mazu will continue to teach us all.
 
Special note: Mazu was originally thought to be male so references to Mazu's gender in this article have been updated from the original publication.

The Congo Clawless otter is listed by the IUCN Red List as a species of least concern, however little is known about its population tread.  It was originally thought to be, and at times still described as, a subspecies of the African/Cape Clawless otter (Aonyx capensis).

Congo Clawless inhabits the rainforests and swamps within the Congo River basin (see map below).  As mentioned during African Spotted-necked otter month in May, Congo Clawless otter habitat overlaps some with Spotted-necked otters as Spotted-necks are present in the Congo basin as well. 

Per the IUCN Red List, Congo Clawless otters are not considered to have major threats at this point; however, they still face habitat loss and are hunted for bushmeat and their skins.
  
Some common names include: Cameroon Clawless, Small-toothed Clawless and Zaire Clawless otter.  The official taxonomic listing is: Kingdom: Animalia; Phylum: Chordata; Subphylum: Vertebrata; Class: Mammalia; Order: Carnivora, Family: Mustelidae; Genus: Aonyx; Species: Congicus.
