Cytochemical staining of leukocytes and platelets in the Florida manatee (Trichechus manatus latirostris): identification of a bilobed monocyte similar to other members of the Paenungulata

Frontiers in Veterinary Science, 2023
Manatees (Antillean-, Amazonian, and African-) and dugongs belong to the Order Sirenia, and when combined with elephants and rock hyraxes, form the Paenungulata. A bilobed mononuclear cell has previously been identified in elephants and rock hyraxes, but
