Virgin dogs can become quite distressed at finding themselves unable to separate during their first copulation, and may try to pull away or run. Dog breeders often suggest it is appropriate for handlers to attempt to calm the mating dogs if they show anxiety once this stage is reached. After mating, the male usually licks his penis and prepuce.
Ulva prolifera (previously Enteromorpha prolifera), also known as the branched string lettuce, is a species of seaweed algae in the family Ulvaceae that can be found worldwide. [ 1 ] Description
The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca , lactuca being Latin for "lettuce".

Green laver (/ ˈ l eɪ v ər, ˈ l ɑː v ər /), known as aonori (アオノリ; 青海苔) in Japan, sea cabbage (海白菜) or hutai (滸苔) in China, and parae (파래) and kim (김) in Korean, is a type of edible green seaweed, including species from the genera Monostroma and Ulva (Ulva prolifera, Ulva pertusa, Ulva intestinalis).
Ulva intestinalis is a green alga in the family Ulvaceae, known by the common names sea lettuce, green bait weed, gutweed, [1] and grass kelp. [2] Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the sea lettuce genus Ulva were placed in the genus Enteromorpha .
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (/ ˌ æ n ɪ ˈ m eɪ l i ə /).With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development.
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
The thallus length ranges from 1.9 –36 cm with a mean length of 18.6 cm. The thallus width ranges from 0.2 to 4.8 cm with a mean width of 1.4 cm. [5] Ulva linza can be distinguished by its smooth thallus, most with a ruffled margin. [5] Ulva linza can tolerate a wide range of salinities and water qualities. [6]
