Tomopteris is a marine planktonic group of polychaete worms. They are very common in all they oceans and seas, many of them living in the deep-sea. All of these tomopteris species emit blue light, called luminescence. Tomopteris helgolandica emits also a yellow light. All Tompteris are transparant . It feeds on other plankton members. (…

Rhabditiform larvae of Hook Worm under Foldscope
Early developmental larval stages (first and second) of soil-borne nematodes such asNecator, Ancylostoma, andStrongyloides, which precede the infectious third-stage filariform larva.
Curvularia spp.
Curvularia is a dematiaceous filamentous fungus. Most species of Curvularia are facultative pathogens of soil, plants, and cereals in tropical or subtropical areas, while the remaining few are found in temperate zones. As well as being a contaminant, Curvularia may cause infections in both humans and animals. Curvularia produces rapidly growing, woolly colonies on potato dextrose agar at 25°C….

Obelia colony
Obelia is a marine colony of hydroid organisms. Each colony of Obelia consists of a horizontal thread-like root called hydrorhiza which is attached to a weed or any substratum ,Obelia is a marine colony of hydroid organisms.
Ameoba
An amoeba, is a term generally used to describe a single celled eukaryotic organism that has no definate shape and that moves by means of pseudopodia. Pseudopodia or pseudopods are temporary projections of the cell and the word literally means “false feet”. The cell uses the pseudopodia as a means of locomotion. The plural of amoeba is…
Cyclops
Cyclops are tiny crustaceans of the family Cyclopidae, also called water fleas. They are usually found in stagnant bodies of fresh water such as wells and ponds in poor agricultural communities in rural or periurban areas. Cyclops are just visible (0.5–2 mm) and can be recognized by their jerky mode of swimming. They feed on…
Oikopleura
Oikopleura dioca, the appendicularians are hermaphrodites and the gonads occupy a relatively large part of the body in mature individuals, sometimes producing the curvature of the trunk of the animal. The length of the tail is three times the length of the body. The tail has a neural chord or notochord, covered by a well-developed…
Embryonic stages of frog
The frog has been historically been used as an amphibian animal model of development due to the ease of observation from the fertilized egg through to tadpole stage. The later metamorphosis of the tadpole to frog has also been studied for hormonal controls and limb development. There have also been many different species used in these developmental…

Chick embryo vertebral development is during the period from 3 to 19 days of incubation.
T.S of liver of rat
The liver is the largest gland in the body. It is located in the upper three regions in the abdomen . Hepatocytes are arranged in hexagon-shaped lobules (classical lobules) about 2 mm in length and 700 μm in diameter.
T.S of Rat Ovary
The paired ovaries of the rat are grape-like structures that vary in gross appearance and size, depending on the stage of the oestrous cycle. The subgross anatomy of the rodent ovary. Covering its surface is a single layer of modified peritoneal mesothelium, the ovarian surface epithelium (OSE), which is continuous with the broad ligament (mesovarium)…
Cypris
Cypris are ostracods (a type of crustacean) and related to mussels and shrimp. They are small, about 1/2 – 2mm long, with a hard outer shell. In freshwater ponds they are usually found scuttling around among the debris at the shallow edges. They swim smoothly with appendages extended from between the two halves of their carapace…

Skin of Octopus
Chromatophores are organs that are present in the skin of many cephalopods, such as squids, cuttlefish, and octopuses, which contain pigment sacs that become more visible as small radial muscles pull the sac open making the pigment expand under the skin.
Radula of Octopus
In molluscs a rasp-like structure of tiny teeth used for scraping food particles off a surface and drawing them into the mouth. The radula is analogous to a tongue and is used to aid in feeding and rasping through the shells of its prey.
