Crocrodile mating, and pregnancy journey

 The process begins with various behavioural interactions, such as snout rubbing and submissive displays. Once mutually satisfied, the male mounts the female, wrapping his tail and back legs around her. Mating occurs in water, where both male and female can be seen intertwined, submerging, and resurfacing.

While the typical courtship routine may last hours, copulation is very short (usually less than 30 seconds). Once the females have mated several times for the season, they begin to build a nest from mud, plants, and sticks to lay their eggs.

The morphology of crocodile spermatozoa was made up of acrosome, head, and tail which corresponded to (5.55±1.20) μm, (12.74±1.57) μm, and (70.67±4.40) μm, respectively. The total length of spermatozoa in estuarine crocodile was measured at (88.96±0.52) μm.

In Florida Bay, the majority of nests are hole nests, with a few mound nests located mainly on islands. A single female typically lays a clutch of between 30 and 60 eggs that incubate for 80 and 90 days. Temperatures of the nest during a period of incubation determine the sex of the hatchling crocodiles.
