Karimi's Fat-tailed Mouse Opossum

distribution

Distribution. Thylamys karimii is endemic to the Cerrado and the Caatinga, and has been recorded in the Brazilian states of Bahia, Goias, Mato Grosso, Minas Gerais, Pernambuco, Piaui, Rondonia, Sergipe, and Tocantins, and in the Distrito Federal (Carmignotto and Monfort 2006, Carvalho et al. 2009, Bruna et al. 2010, Carmignotto and Aires 2011, Bonvicino et al. 2012, Bezerra et al. 2014). The species has not been reported for Bolivia, but its presence on the Serrania de Huanchaca in the Santa Cruz department of that country might be expected (Giarla et al. 2010).

activity

Activity patterns. Karimi’s Fat-tailed Opossum is apparently nocturnal. The captive type specimen was highly active at night and lethargic during the day when a drop in body temperature to about room temperature (c. 20 - 25 ° C) was noted. It did not, however, survive a quick temperature drop to 15 ° C.
