[89] [77] She lays one to three (usually two) small, leathery eggs (similar to those of reptiles), about 11 mm (7 ⁄ 16 in) in diameter and slightly rounder than bird eggs. [90] The eggs develop in utero for about 28 days, with only about 10 days of external incubation (in contrast to a chicken egg, which spends about one day in tract and 21 ...
Tuatara, however, lack copulatory organs, and so the male and female simply press their cloacas together as the male discharges sperm. [120] Most reptiles lay amniotic eggs covered with leathery or calcareous shells. An amnion (5), chorion (6), and allantois (8) are present during embryonic life. The eggshell (1) protects the crocodile embryo ...
Male American alligators use infrasound to attract females. Eggs are laid in a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. Young are born with yellow bands around their bodies and are protected by their mother for up to one year. [12] This species displays parental care, which is rare for most reptiles.
1) Male and female sea turtles age in the ocean and migrate to shallow coastal water. 2) Sea turtles mate in the water near offshore nesting sites. 3) The adult male sea turtles return to the feeding sites in the water. 4) Female sea turtles cycle between mating and nesting. 5) Female sea turtles lay their eggs.
If the sand is over 30 degrees Celsius, it is a female and if below 30 degrees Celsius, the egg is a male. Incubation period can last from 80 to 90 days in Florida and 110 days in South Carolina. The eggs will stay in the uterus of the female for 60 days until oviposition occurs, they will use their uterine epithelium to supply "pumping water ...

The mammalian male reproductive system contains two main divisions, the penis and the testicles, the latter of which are where sperm are produced and usually held in a scrotum. [5] In humans, both of these organs are outside the abdominal cavity , but they can be primarily housed within the abdomen in other animals.
Some reptiles use incubation temperatures to determine sex. In some species, this follows the pattern that eggs in extremely high or low temperatures become female and eggs in medium temperatures become male. [14] Within the mechanism, two distinct patterns have been discovered and named Pattern I and Pattern II.
