These slimy creatures may look like aliens from another planet but they are actually the life teeming inside a single drop of pond water.

The colourful organisms were captured using a photography technique called high-definition microscopy in a lab in Ohio by photographer Peter Matulavich.

he pond safari pictures show everything from a single-celled paramecium organism moving through bacteria to a defecating 10mm creature called hydra and a cluster of Euglena Protozoa that are seen in such high numbers they have been known to make entire ponds and puddles appear green or red.

This image shows a microscopic view of the small freshwater animal Hydra as it defecates in a single drop of water in a lab in Ohio. The creature grows around 10mm long and biologists are keen to study them because they appear not to age or die

This pair of Blepharisma, pictured, are sharing genetic information inside a drop of pond water. Blepharismas are what's known as protists, or single cellular organisms. They are filter feeders, which means they suck in water, eat bacteria and algae and filter the clean water back out of their bodies

Amazing! Microscopic life in a single drop of pond water

Microscopy is the method of using microscopes to view samples and objects that cannot be seen by the naked eye.

Matulavich's first image shows a microscopic view of the small freshwater Hydra as it defecates in a single drop of water in a lab in Ohio.

The creature grows around 10mm long and biologists are keen to study them because they appear not to age or die.

They are found in most unpolluted freshwater ponds, lakes and streams and possess what's called radial symmetry. This means that its body has a symmetrical shape and its body parts are evenly distributed.

Matulavich managed to also capture a pair of Blepharisma. Blepharismas are what's known as protists, or single cellular organisms. They are filter feeders, which means they suck in water, eat bacteria and algae found inside this water and filter the clean water back out of their bodies.

Filter feeders can help regulate the ecosystem of the freshwater in which they live.

The Actinosphaerium is part of a small group of protists called actinophryids and are mostly found in freshwater, especially lakes and rivers, but some have been found in soil too. Each actinophryid have a single cell and are roughly spherical.

The outer portion of the cell, or ectoplasm, is filled with tiny vacuoles, or bubbles, that help the creature to float.

The Actinosphaerium variety of actinophryid are between 200-1000 micrometres in diameter.

This shot shows a high-definition microscopic view of a Planarian - a type of flatworm capable of regenerating after being cut in half. A study in July by Boston University discovered that when a Planarian regrows its head, it is also capable of regrowing memories. They live in both saltwater and freshwater ponds and rivers

Other protists caught on camera in Ohio include this cluster of Euglena Protozoa. They are seen in such large numbers that they can colour the surface of ponds and ditches completely green. Species of Euglena were among the first protists to be seen under the microscope and were recorded as early as 1674

The worms live in both saltwater and freshwater ponds and rivers and they have two eye spots that can detect the intensity of light. These spots act as photoreceptors and are used to move away from bright light sources.

This bundle of Panagrellus Nematodes is a common feature in aquariums and is also known as the microworm. It is a tiny roundworm used as food for a variety of fish, especially when they first hatch. The microworm is about 50 micrometres in diameter and just over one millimetre in length which makes it barely visible to the human eye

Cytoplasm flowing through water was captured by Matulavich, pictured. The cytoplasm is made up of everything within an organism that sits outside of the nucleus, enclosed within the cell membrane. The cytoplasm can also include the cytoskeleton - fibres that help support the cell and maintain its shape

This cluster of Micrasterias algae was photographed as it floated through a drop of pond water. It is also called green algae. Micrasterias can reproduce both asexually and sexually. During sexual reproduction two organisms fuse their haploid cells to form a zygote, or yolk. This zygote forms a thick protective wall which lets the organism remain dormant for months to survive cold winters and long droughts. When the conditions are right, the organism, known as a zygospore, is born
