After courtship, the male newt deposits a spermatophore. The female newt is supposed to pick it up, but this poor guy's date fled.

And finally after dropping a spermatophore, the female castaneiceps moves in and picks it up.

This male pursued the female by standing in front of her, raising his wings to expose his metanotal gland, and then sang to get her attention. Watch as the female feeds from the metanotal gland -- then curls her abdomen down so the the distal tip is within reach of the distal tip of the male's abdomen. Note how the male grabs her with the two projections (cerci) at the tip of his abdomen -- pulls her tightly against him -- and then there is a sudden release as the two separate. If you look closely, you can see the small pinkish gold orb - the spermatophore - now attached on the far left side of the female's abdomen. It has a slender tubelike port which has been inserted into the female, and the sperm begins draining immediately. Watch as the female backs away from the male -- he frantically starts singing again to bring her back to feed from his metanotal gland. This is to distract her from plucking the spermatophore off before the sperm has completely emptied into her.

Yellow-spotted salamanders inciting each other to reproduce. The white things are packets of sperm left by the males, to be picked up by the females for internal fertilization later. Filmed and narrated by Joe Britton

This pair was filmed in an indoor enclosure. The male began singing to the female almost the instant they were placed together. At the start of the clip you see the two distal ends of their abdomens quickly separate. Look for the tiny yellowish sac now attached at the back of the female. The female continues to feed from the male's metatnotal gland. More than 3/4 through the clip you will see the female push one leg against the male's wings and she stops feeding. The male immediately begins singing to entice her back. This strategy delays the female from plucking the spermatophore off before all the sperm have emptied into her.

Spawning is initiated by the male, who swims around, raising its tail and making vigorous writhing motions. The male nudges the female's vent occasionally and then leads her around the tank. The spermatophore is a common "device" in the salamander and newt world (an old one, about 12 hours old, is pictured beside this paragraph). It is a packet of sperm attached to the top of a cone of jelly. The male deposits between 5 and 25 of these around the tank and attempts to lead the female over them. She picks up the sperm cap (from one or more spermatophores) in her cloaca - fertilisation takes place internally. She may also nudge the male's vent, and this can lead to a prolonged "dance" around the tank. Between a few hours and two days later, she commences spawning, laying each egg individually. She will lay them on the leaves of plants, if available, but if not, she will place them about the tank, attaching them to rocks, pipes and any other object available. There may be between 100 and over a thousand eggs laid in one spawning, depending on the size of the female and if she is in optimal condition at spawning. After the female has finished laying, it's best to remove her and the male.

This is some eastern newt breeding behaviour and spermatophore depostion.

The grasshopper's reproductive system consists of the gonads, the ducts which carry sexual products to the exterior, and accessory glands. In males, the testes consist of a number of follicles which hold the spermatocytes as they mature and form packets of elongated spermatozoa. After they are liberated in bundles, these spermatozoa accumulate in the vesicula seminalis (vas deferens). In females, each ovary consists of ovarioles. These converge upon the two oviducts, which unite to create a common oviduct which carries ripe eggs. Each of the ovarioles consists of a germarium (a mass of cells that form oocytes, nurse cells, and follicular cells) and a series of follicles. The nurse cells nourish the oocytes during early growth stages, and the follicular cells provide materials for the yolk and make the eggshell (chorion). During reproduction, the male grasshopper introduces sperm into the ovipositor through its aedeagus (reproductive organ), and inserts its spermatophore, a package containing the sperm, into the female's ovipositor. The sperm enters the eggs through fine canals called micropyles. The female then lays the fertilized egg pod, using her ovipositor and abdomen to insert the eggs about one to two inches underground, although they can also be laid in plant roots or even manure. The egg pod contains several dozens of tightly-packed eggs that look like thin rice grains. The eggs stay there through the winter, and hatch when the weather has warmed sufficiently. In ...

My 2 centruroides margaritatus beginning the mating dance. It took over 13 hours for them to successfully mate, mainly because it took the male a while to find a suitable place to deposit his spermatophore, which the female absorbs. Also, they're siblings, but inbreeding scorps is ok

The California newt (Taricha torosa) is a newt. It is also referred to as the Oregon newt or orange bellied newt. They can grow to be 8 inches (20 cm) in length, which is larger than most salamanders. T. torosa adult length can range from 5 inches (13 cm) to 8 inches (20 cm). [1] The difference between these two seems to be only in the location in which the newt is found. California newts exist primarily on the California coastline and in the Sierra Nevada. This is because they prefer less humid climates than the rough skinned newts. During the non-breeding season the newts are land dwelling, preferring rock crevices and logs. While breeding, the subspecies torosa torosa prefers slow moving pools in coastal streams. Reproduction occurs generally between December and early May. Typically the adult newts will return to the pool in which they hatched. After a mating dance, the male mounts the female and rubs his chin on her nose. He then attaches a spermatophore to the substrate, which she will retrieve into her cloaca. The egg mass released by the female contains between 7 and 30 eggs, and is roughly the consistency of a thick gelatin dessert. Typically the egg masses are attached to stream plant roots or to rocky crevices in small, slow moving pools. But they have also been known to be attached to underwater rocks or leaf debris. While shallow in a wide sense, these pools are rather deep relative to the average depth of a Southern California stream, varying in depth from ...

Copulation in Octopus chierchiae. The male on the right inserts his third right arm (hectocotylus) into the female's mantle cavity. (The female is on the left.) If you look carefully, you can see a groove running the length of the hectocotylus. During insemination a packet of sperm (spermatophore) is transported along this groove and is deposited in the female's genital opening. Octopus chierchiae is a rare dwarf octopus from the Pacific coast of Central America that is iteroparous meaning that unlike most octopus, the female does not die after brooding her young.
