It is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended. In addition to hemocytes, the plasma also contains many chemicals. It is the major tissue type of the open circulatory system characteristic of arthropods (for example, arachnids, crustaceans and insects).
Hemocytes are phagocytes of invertebrates. Hemocytes in Drosophila melanogaster can be divided into two categories: embryonic and larval. Embryonic hemocytes are derived from head mesoderm and enter the hemolymph as circulating cells. Larval hemocytes, on the other hand, are responsible for tissue remodeling during development.
Colloidal vital dyes, such as ammonia carmine and trypan blue, are rapidly and preferentially taken up by insect pericardial and garland nephrocytes. [10] Nephrocytes, but not hemocytes of the common blow fly (Calliphora) avidly endocytose and degrade ligands that are also recognized by stabilin-2 of mammalian scavenger endothelial cells. [11]
Paddle-tailed sea snakes prey on fish eggs extracted from coral reef crevices. Some tree snakes have specialized jaws to extract snails from their shells, and use special chemicals to "de-slime" them.
The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.

The Western terrestrial garter snake species is common in most habitats but spends a lot of time in water. These snakes are typically gray-brown or black with a checkered pattern and yellow ...
Winter-Themed Christmas PieCakes. He created a cake and pie dessert that features three desserts in one: pecan pie, pumpkin pie, and spice cake.
Fat body is a highly dynamic insect tissue composed primarily of storage cells. It is distributed throughout the insect's internal body cavity (the haemocoel ), in close proximity to the hemolymph as well as organs such as the epidermis , digestive organs and ovaries .
