摘要：Nesting ecology of Morelet’s crocodile (Crocodylus moreletii) has been documented since 1940. However,only 2 nests constructed on floating vegetation have been recorded. Here, we presented additional information from amainland population of C. moreletii in the Ciénega de Cabezas wetland, San Luis Potosí, describing 2 nests constructedon floating mats of cattails. The nests were constructed using Typha sp., close to the main channel. One nest was lostdue to flooding, and contained 32 eggs. Seven eggs had a mean 72.6 ± 2.63 mm length (range = 70.0 -75.0 mm), 45.0± 2.30 mm width (range = 41.0-48.0 mm), and 140.7 ± 2.98 mm diameter (range = 136.0-145.0 mm). We suggest thatthe use of floating vegetation for nesting by C.
