Tomopteris

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. (…

Unknown scyphozoan

Cnidarians are a phylum of principally marine invertebrates that includes inter alia coral, anemones, and jellyfish. A defining feature of a cnidarian is its nematocyst or cnidocyst, the secretory subcellular capsule responsible for delivering a cnidarian’s characteristic sting. The kinetics of nematocyst discharge can occur on the nanosecond scale, providing an acceleration upwards of 5…

Crab shell

I tried to observe sand bubbler crab shell through Foldscope which i found in sand. I observed it in almost no light.

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.

What does the sand on a beach contains?

Yesterday I was at Girgaon chaupati beach. I lifted a pinch of sand to check what it contains. It had many tiny objects which gave indications of the rich marine life. I could not identify the organisms just by looking at the broken parts but nonetheless it was fsdcfascina to see so many beautiful objects…

Sea Snail Eggs – Hopkins Marine Station pt. 2

Hello everyone! I’ve been meaning to follow up on my Hopkins Marine Station post, so I’ll limit the words and get right to some videos that I’m excited about, focusing on sea snail eggs. Here’s a look at the sample. The left image is of many snail egg casings clustered together (also note the gorgeous…

A food web in a fluid droplet (algae, rotifers, and anemone)

In my ongoing quest to explore marine microfauna, I recently observed rotifers under a Foldscope. Like many motile marine invertebrates, rotifers use cilia to maneuver through the water column. They also use these cilia to feed by generating currents.  The anterior end of the animal is in the top right of the pictures, and there…

Building my first Foldscope!

Ever since I met Manu at my first TED conference in Long Beach back in 2012, I have been a wild fan of Foldscope. I still remember walking around one of the fancy cocktail parties with him as he pulled a handful of these origami microscopes out of a pouch around his neck and showed…

Help identify this worm

Part 1:  I just stumbled upon a strange “two colored worm” in algae mats on a rocky shore in Gulf of Mexico. It was a very agile worm; and I got some great videos on my Foldscope. I know the number of marine worm species is astronomical; but this is a really strange body. I…
