What animals have hemipenes?
A hemipenis (plural hemipenes) is one of a pair of intromittent organs of male squamates (snakes, lizards and worm lizards). Hemipenes are usually held inverted within the body, and are everted for reproduction via erectile tissue, much like that in the human penis.
Does a turtle have a hemipenis?
A single, fleshy penis is present in male turtles and crocodilians (Fig. 19.11a). Snakes and lizards have paired, membranous hemipenes, which lie in the base of the tail and are everted during copulation (only one hemipenis is used during copulation) (Fig. 19.11b).
Do birds have hemipenis?
Hemipenes are one of the shared derived characters of squamates (snakes and lizards), distinguishing them from other reptiles (tuataras, turtles, crocodilians, and birds), all of which have either a single or no penis.
Do crocodiles have hemipenes?
The hemipenes of lizards and snakes are elongated tubular structures lying in the tail. The penis of a crocodile or turtle is protruded through the cloacal opening wholly by means of a filling of blood space (sinuses) in the penis; protrusion of a lizard’s…
Do snakes have cloacas?
In snakes and lizards, the external genitals get a little funkier. These reptiles have paired external genitals, even though they only use one at a time during mating. But all of these genitals spring out of the same embryonic structure, called the cloaca.
How do snakes mate?
To mate, snakes need only to align the base of their tails at the cloaca, an opening serving both reproductive and excretory systems. The male extends his hemipenes, the two-pronged sex organ stored in his tail, and with each half deposits sperm into the female’s cloaca.
Do snakes fart?
And Rabaiotti did find that fart answer for her brother: yes, snakes fart, too. Sonoran Coral Snakes that live across the Southwestern United States and Mexico use their farts as a defense mechanism, sucking air into their “butt” (it’s actually called a cloaca) and then pushing it back out to keep predators away.
Do lizards have cloacas?
How do you tell if a snake is a boy or a girl?
You may be able to tell what gender your snake is by the shape of their tail. Male snakes have reproductive organs called hemipenes. The hemipenes are tubular-shaped organs that sit inside the snake’s body just below the cloacal opening. As a result, a male snake’s tail is usually thicker and longer than a female’s.
What color is a fart?
The flame from a fart where hydrogen is the primary fuel will burn yellow or orange, while an atypically high methane content will turn the flame blue.

What is the importance of Blood Morphology in hematology?
Blood Morphology. Blood morphology adds greatly to the value of a routine blood count. Skillful examination of a well-made blood smear constitutes the most valuable single procedure in the hematology laboratory. In spite of normal blood count figures, careful observation of blood morphology suggested previously unsuspected disorders.
What makes a female hemipen different from a male hemipene?
For example, species with branched hemipenes have females with branched cloacas, and species with many spikes have females with thicker cloacal walls, compared to those of species with males having little or no spines.
What kind of snake has an everted hemipenis?
An everted hemipenis of a North American rattlesnake (Crotalus adamanteus). A hemipenis (plural hemipenes) is one of a pair of intromittent organs of male squamates (snakes, lizards and worm lizards).
