A capsule or pocket inclosing a number of spermatozoa. They are present in many annelids, brachiopods, mollusks, and crustaceans. In cephalopods the structure of the capsule is very complex.
the caudate version of sperm. When salamanders mate, there's a complicated courtship display, and it ends with the male depositing a spermatophore on the ground; the female picks it up with her cloaca. The eggs are fertilized inside the female, and then she lays the eggs.
a structure deposited on substrates by courting male salamanders that typically consists of a mass of semial fluid (sperm cap) resting upon a gelatinous base
a packet or capsule containing sperm that is transmitted to the female during copulation. Spermatophores are manufactured by the accessory glands of the male reproductive system.
A sperm-containing sac that the male passes to the female during copulation. In crickets and katydids the spermatophore is usually attached externally with the spermatophore tube inserted into the female genital opening to allow the sperm to pass from the bulb of the spermatophore into the female's spermatheca. In most crickets, the spermatophore is bare (e.g., tree crickets) but in most katydids it is surrounded by a large mass of gelatinous material known as a spermatophylax.
cone-shaped jellylike mass topped with a sperm cap, deposited by male salamanders during courtship
a packet or capsule containing spermatozoa which is produced by the male to be transferred to the female for fertilisation.
a gelantinous mass containing spermatozoa, which is deposited by the male salamander during breeding
In salamanders, males will deposit a ball of sperm, or male reproductive cells, on the ground after courtship with the female. The female will use her cloaca to grasp the spermatophore to complete copulation.
The 'parcel' of sperm that is passed from male to female during copulation.. If sp. is written as part of a species' name, as in Baculum sp. for example, this means that the genus of the species is known, but no official name has yet been given to that specific species. pp. Sometimes people write such things as Sphodromantis spp. By this they are referring generally to all species of that genus, in this instance the genus ' Sphodromantis'.
The package of sperm that a male cockroach transfers to a female for mating purposes.
In shrimp, the "packet" that contains the sperm. The spermatophore is attached to the female shrimp near the gonopore, either on the outside of the exoskeleton or under exoskeletal plates depending upon the species.
A spermatophore is a capsule or mass created by males of various invertebrate species, containing spermatozoa and transferred in entirety to the female's ovipore during copulation. It may contain nourishment for the female, in which case it is called a nuptial gift, though recent research has indicated that this "gift" provides little nutrient value.
