An international team of scientists has succeeded in artificially inseminating the last female Yangtze giant softshell turtle. Will babies be far behind?
She: “What are you writing about?” Me: “Cognition in cold-blooded animals.” She: “Hot.” Most people who study cognition focus on mammals or birds.
A sea turtle’s life begins in darkness. After about 60 days of incubation inside their eggs, turtle hatchlings use a temporary tooth called a caruncle to break out of their shells.
In a further effort to relieve Turtle Guilt (see the previous turtle-themed Tet Zoo article), I give you the following article devoted wholly to kinosternids, an exclusively American group of about 25 species of seemingly mundane and unspectacular turtles.
