“…Several hematological studies have been performed for manatees, but long-period studies are still necessary. Although, the values for the marine manatee (White et al, 1976;Medway et al, 1982aMedway et al, , 1982bMedway et al, , 1982c and its subspecies inhabiting Florida (Trichechus manatus latirostris) are welldefined (; Bossart & Dierauf, 1990;Bossart et al, 2001), data for other sirenian species are considered scarce (Allen et al, 1976;Colares et al, 1992;Converse et al, 1994;Rosas et al, 1999). Recently, Silva et al (2007) reported serum chemistry values for captive Antillean manatee adults, not verifying differences between genders.…”

The Antillean manatee (Trichechus manatus manatus) is the most endangered aquatic mammal in Brazil. Sampling blood data from such critically endangered marine mammal species is extremely challenging. Although several hematological studies have been developed for captive manatees, captivity studies addressing the environmental and physiological effects on blood values are scarce. The present work describes blood biochemistry values for captive Antillean manatee adults and calves and verifies the occurrence of possible physiological adjustments due to age, sex, and dietary influences. Blood from 13 clinically healthy manatees (eight calves and five adults) were analyzed for 13 blood serum chemistry parameters using a semi-automatic analyzer. Descriptive analysis was performed for all parameters, and differences between sex and age were determined. Calves had higher means of urea (6.29 ± 5.58 mg/dL), total proteins (5.07 ± 0.94 g/dL), globulin (3.06 ± 1.32 g/dL), and alanine aminotransferase (6.19 ± 2.18 U/mL), levels, and lower means of creatinine (1.42 ± 0.64 mg/dL), aspartate aminotransferase (7.24 ± 3.21 U/mL), phosphate (3.03 ± 1.63 mg/dL), and uric acid (0.71 ±0.17 g/dL) than adults. Further studies are necessary, especially when considering handling and alimentary management in captivity, to provide important data for better monitoring and clinical management of manatees.

“…A ssis et al (1988) proposed fission and/or fusion type rearrangements of acrocentric chromosomes as a mechanism responsible for the karyotypic divergence between the Amazonian manatee and the Florida manatee, where the diploid numbers for these two species is 2n=56 and 2n=48, respectively. A ssis et al (1988) assigned a fundamental number (FN) of 82 for the Amazonian manatee, based on the description of 14 bi‐armed and 13 acrocentric autosome pairs, and implied an FN=78 for the Florida manatee, based on the use of similar terminology employed in a previously published karyotype of the Florida manatee, which described 16 bi‐armed and 7 acrocentric autosome pairs (W hite et al 1976). Unfortunately, the exact criteria utilized for the FN calculation were not provided, making speculation regarding the FN discordance and apparent variation in the numbers and sizes of metacentric or submetacentric chromosomes between these two species problematic.…”

“…Although the application of chromosome banding and/or special chromosome staining techniques, to facilitate individual homolog identification and structural chromosome features, has been attempted in some marine mammal species (A rnason 1974a,b; D uffield 1974; A ssis and B arros 1987; B ielec et al 1997), published cytogenetic data for the order Sirenia are limited. The majority of existing chromosome studies of marine mammals, primarily cetaceans, have been more commonly limited to solid stained chromosomes of a small number of individuals, or cell lines, of a given species (D uffield et al 1967; A rnason 1969, 1970a,b; L oughman et al 1970; A rnason and B enirschke 1973; W hite et al 1976, 1977; A ssis et al 1988). Most of the earlier chromosome studies were conducted at a time when chromosome‐banding techniques were in their initial stages of development.…”

Detailed chromosome studies were conducted for the Florida manatee (Trichechus manatus latirostris) utilizing primary chromosome banding techniques (G-and Q-banding). Digital microscopic imaging methods were employed and a standard G-banded karyotype was constructed for both sexes. Based on chromosome banding patterns and measurements obtained in these studies, a standard karyotype and ideogram are proposed. Characterization of additional cytogenetic features of this species by supplemental chromosome banding techniques, C-banding (constitutive heterochromatin), Ag-NOR staining (nucleolar organizer regions), and DA/DAPI staining, was also performed. These studies provide detailed cytogenetic data for T. manatus latirostris, which could enhance future genetic mapping projects and interspecific and intraspecific genomic comparisons by techniques such as zoo-FISH.

“…Solid stained chromosome studies were completed on a limited number of individual manatees, establishing the chromosome number as 2N = 48 for the Florida manatee [9,10] and 2N = 56 for the Amazonian manatee ( Trichechus inunguis ) [11]. Following solid staining, chromosome-banding procedures allowed for the identification of individual chromosome regions.…”

Chromosome painting in the manatee supports Afrotheria and Paenungulata

Background: Sirenia (manatees, dugongs and Stellar's sea cow) have no evolutionary relationship with other marine mammals, despite similarities in adaptations and body shape. Recent phylogenomic results place Sirenia in Afrotheria and with elephants and rock hyraxes in Paenungulata. Sirenia and Hyracoidea are the two afrotherian orders as yet unstudied by comparative molecular cytogenetics. Here we report on the chromosome painting of the Florida manatee.
