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. (…

Fungus grown on bark

I came across this fungus growing on dead bark of betel nut tree. I picked few fungus, observed there and then using paper slide and cello-tape which I carry in my foldscope kit. I collected the bark sample to prepare the slide of the fungus using Lactophenol blue stain for identification.

Holotrich Protozoa identification in a field setting

DBT Foldscope scheme – “Foldscope for diagnosis of Rumen acidosis and Parasitic infection in cattle”. This post is in response to Manu Prakash’s comment on our previous post (Holotrich protozoa – from Rumen fluid). Rumen fluid was collected from an healthy cow  (Figure 1) in a sterile container (figure 2).  A drop of rumen fluid was…

Spores of Fern

Ferns are reproduced from spores that are gathered in clusters called sori, which are usually on the underside of the fronds. The spores can be yellow, green, brown, or black. The sori are sometimes covered with a membrane called an indusium, which will lift up when the spores are ripe.

Foldscopes at UCT Youth Open Day – 4/30/19

Last Tuesday, the University of Cape Town (UCT) opened its doors to some eager high school students from local township schools for a Youth Open Day outreach event. This event was organized by a lovely UCT medical student I met recently, Theodora, who is part of the Career Development UCT Surgical Society. I met Theo…

Embryonic development of human lice

If you have kids, you probably already know all about lice. Or maybe you think you know all about lice – and you just want to crush it. But wait, just wait a second, pull out your foldscope next time anyone talks about lice and give it a good strong look. And you can crush…

Pollen of Wild almond flower

Wild Almond Tree is a soft wooded tree that can grow up to 115 feet tall. The origin of the name of the bad-smelling Sterculia genus comes from the Roman god, Sterquilinus, who was the god of fertilizer or manure. 

Aphids from Fenugreek plant

I found these while inspecting what looked like white specs of dust on fenugreek (Methi in India) leaves of my garden. The video also shows a larger aphid with what could possibly be an egg in its hind. Thanks to the Foldscope team that replied and guided me on Instagram. I learned something new!

Larval stages of Filarial nematodes

One milliliter of blood was mixed with nine milliliter of 2% formalin. The mixture was centrifuged at 5,000 rpm for 5 min and the supernatant was discarded. To the sediment, few drops of methylene blue solution was added. A drop of the solution was placed on slide with a cover slip above and examined under…

Wiggly Water Bears

This charismatic creature is called a tardigrade (also known as a water bear). The scientific name for the animal shown here is Hypsibius exemplaris. These amazing animals were kindly provided to the Marine Biological Laboratory’s Embryology Class during Summer 2018 by Dr. Bob Goldstein from UNC Chapel Hill. Dr. Goldstein’s lab has turned these resilient…

Brine shrimp

I got some brine shrimp cyst (Artemia salina) for fish feeding and got to witness its hatching.

Brachiolaria larva

Brachiolaria is the second stage of larval development in many starfishes. it has bilateral symmetry.

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.

Ovule of Hibiscus and its transverse section

These are the flower’s eggs, located inside the ovary. Upon fertilization by pollen, they will eventually grow into a seed. In fruit plants, pollen will not only spark the growth of a seed, but a surrounding fruit as well.

An Aurelia scyphistoma

The scyphistoma is a sessile, larval (non-reproductive) stage of Aurelia, which in time turns into a strobila. Scyphistoma sometime multiplies by budding from stolons. After some time scyphistoma undergoes transverse fission at its oral end, a process called strobilation.  .


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 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 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…

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.
