The Black River Lower Morass: a threatened wetland in Jamaica

The Black River Lower Morass is Jamaica's largest wetland, and is a refuge for two endangered species—the American crocodile and the West Indian manatee—as well as for a host of other plants and animals. It is internationally important for many birds and a vital economic resource for 20,000 people. Proposals for peat mining and drainage for agriculture now threaten this valuable area. The author has a long-standing interest in the wetland, having studied the American crocodile there since 1975.

West Indian Manatee

The West Indian manatee Trichechus manatus manatus has declined rapidly in many parts of its range and appears on the IUCN's list of endangered species. But in British Honduras last summer the author found an abundance of manatees all along the coast. Moreover, predation is at a minimum: the people who formerly ate manatee meat now show little interest in it, and the alligator, its only other predator, has been persecuted almost to extinction.

West Indian Manatee

ABSTRACT: The West Indian manatee (Trichechus manatus) is one of the most threatened aquatic mammals in Brazil, and is currently classified as “endangered” (MMA). The objective of this study was to characterize histologically the reproductive tract and fetal annexes of stranded manatees in northeastern Brazil. Tissue samples were collected from the reproductive tract of 23 manatees, which were fixed in 10% buffered formalin, processed using standard histological protocols and stained with hematoxylin eosin. We qualitatively described the histological and histomorphometric characteristics of each structure. Six ovaries were analyzed. In four ovaries, we found a large number of primordial and primary follicles. Two ovaries were different from the others: one had inflammatory infiltration and the other had a thickening in the cortex and absence of follicles. We also analyzed seven uteri (of which four were in the proliferative phase, two in the secretory phase, and one in the recovery phase), four placentas, one vagina, six testes (four were in the immature phase, one in the pubertal phase, and one in the mature phase), two epididymides, two penises, and one umbilical cord. The histological and morphometric findings in our work will support future analyses of the reproductive tract of T. manatus from Brazil.
