Kassina senegalensis - The Senegal land frog is a common species found throughout the savannah regions of Africa. It is a small frog, 25 to 40 millimeters in size, without noticeable differences between male and female. The Senegal land frog has several sub-species distributed over a wide area. Coloration varies by region, but is normally grey with a black dorsal strip, some spotting, and additional striping along the flanks. The call of the frog rises above other sounds during the African rainy season.

Slavery had existed throughout the world, but it took on a new dimension with the beginning of the trans-Atlantic slave trade. The African slave trade began in the 16th century and continued far into the 19th century. The area along the mouth of the Gambia River was one staging area among several others on the West African coast serving as holding camps and shipping centers. More than 3,000,000 people were shipped out as slaves from this area of Africa; the majority were bound for the Americas.
