Algeria is a transit and, to a lesser extent, destination country for men and women subjected to trafficking in persons, specifically forced labor and forced prostitution.
 Most commonly, sub-Saharan African men and women enter Algeria voluntarily but illegally, often with the assistance of smugglers, for the purpose of traveling to Europe.
 Some become victims of trafficking: men may be forced into unskilled labor and women into prostitution to repay smuggling debts.
 Criminal networks of sub-Saharan nationals in southern Algeria facilitate this irregular migration by arranging transportation, forged documents, and promises of employment.
 Reliable statistics on the number of potential victims are not available from the government or non-governmental organizations (NGOs).
 One NGO estimates that the populations most vulnerable to trafficking include between 10,000 and 15,000 illegal sub-Saharan African migrants.
The heaviest land mammal has a weight up to 6 short ton , the African Elephant.
 This enormous mammal measures approximately 24 ft and eats 500 lbs of vegetation like grasses and leaves a day.
 Their two elongated teeth-tusks can grow continuously during their lives and reach about 9 ft in length.
 The average walking speed of an elephant is 4.5 mph , but they can run at recorded speeds up to, and sometimes exceeding, 15 mph .
The Irvingtonian North American Land Mammal Age on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 1,800,000 to 240,000 years BP, a period of .
 Named after an assemblage of fossils from the Irvington District of Fremont, California, the Irvingtonian is usually considered to overlap the Lower Pleistocene and Middle Pleistocene epochs.
 The Irvingtonian is preceded by the Blancan and followed by the Rancholabrean NALMA stages.
The Rancholabrean North American Land Mammal Age on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from less than 240,000 years to 11,000 years BP, a period of .
 Named after the famed Rancho La Brea fossil site (more commonly known as the La Brea tar pits) in Los Angeles, California, the Rancholabrean is characterized by the presence of the genus "Bison" in a Pleistocene context, often in association with other extinct Pleistocene forms such as "Mammuthus".
 The age is usually considered to overlap the Middle Pleistocene and Late Pleistocene epochs.
 The Rancholabrean is preceded by the Irvingtonian NALMA stage.
Kolponomos is an extinct genus of carnivoran mammal that existed in the Late Arikareean North American Land Mammal Age, early Miocene epoch, about 20 million years ago.
 The genus was erected in 1960 by Ruben A. Stirton, a paleontologist at the University of California Museum of Paleontology, Berkeley, for the species "K. clallamensis", on the basis of a partial skull and jaw found on the Olympic Peninsula.
 At the time, Stirton questionably assigned it to Procyonidae, its systematic position remained problematic until the discovery of more fossils including a nearly complete cranium from the original locality of "K. clallamensis" which helped identify it as part of the group from which Pinnipeds evolved.
The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of European land mammals.
 These biozones cover most of the Neogene and Paleogene systems (i.e. rock layers which are 65.5 to 2.588 million years old).
 In cases when fossils of mammals are abundant, stratigraphers and paleontologists can use these biozones as a more practical regional alternative to the stages of the official ICS geologic timescale.
 European Land Mammal Mega Zones are often also confusingly referred to as ages, stages, or intervals.
The Museum of African Culture is a museum in Portland, Maine, United States, that specializes in Sub-Saharan African tribal art and culture.
 Changing exhibits also include art inspired by the African diaspora, and the museum's programs include music, storytelling, films, poetry, literature, healing ceremonies and other Sub-Saharan African cultural traditions.
 Collections include wooden masks, figures, textiles, household objects and tools.
 It was established in 1998 and, as of 2010 , had over 1,500 pieces of art.
 It is the only museum in northern New England devoted to African arts and culture.
The common hippopotamus ("Hippopotamus amphibius"), or hippo, is a large, mostly herbivorous and aggressive mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis").
 The name comes from the ancient Greek for "river horse" (ἱπποπόταμος ).
 After the elephant and rhinoceros, the common hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl.
 Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the Hippopotamidae are cetaceans (whales, dolphins, porpoises, etc.) from which they diverged about .
 The common ancestor of whales and hippos split from other even-toed ungulates around .
 The earliest known hippopotamus fossils, belonging to the genus "Kenyapotamus" in Africa, date to around .
This is a list of the mammal species recorded in the Balearic Islands, Spain.
 All three land mammal species once endemic to the islands (Majorcan giant dormouse, Balearic shrew and the goat-like ruminant "Myotragus balearicus") are currently extinct, while those presently found on the archipelago have been introduced voluntarily or accidentally by humans in different colonization waves beginning in the Neolithic.
The Kazinga Channel in Uganda is a wide, 32 km long natural channel that links Lake Edward and Lake George, and a dominant feature of Queen Elizabeth National Park.
 The channel attracts a varied range of animals and birds, with one of the world's largest concentration of hippos and numerous Nile crocodiles.

Question: What sub-Saharan African mammal is the third-largest type of land mammal and a large concentration of them can be found at the Kazinga Channel?
Answer: hippopotamus
