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…

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)…

Megalopola

Megalopa larva has a large un-segmented cephalothorax with all 13 pairs of appendages like those of a crab, abdomen is straight and in line with cephalothorax, it is like the abdomen of prawn with 6 pairs of well formed pleopods, In crabs the nauplius is passed in the egg, it hatches as a zoaea which…

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…

Zebrafish embryonic stage

Transition stage between Oblong to sphere stage of blastula period in zebrafish embryonic developement

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.
