I got 10min+ of footage of this rotifer moving through the leaf of a
Syntrichia princeps specimen I collected.

Fascinating!

The moss was gathered from Bluffs Park October 23 though these images were captured today, December 11, 2016.

This is a Bdelloid rotifer (Rotifer-19984-5-LI in the foldscope classfication) that grew in a lichen suspended in water for 2 weeks. It might be from the lichen as I have seen this at least twice independently. For more details and videos see,

Description

Rotifers are mostly freshwater animals and are some of the smallest members of multicellular animals. They are very impressive microorganisms because they have a very simplified organ system and can survive in harsh conditioned live for a very long time.(MG 2016) The most famous part about a rotifer is its Corona, a feature which looks like two spinning wheels made of beating cilia… the corona has several functions which aid in its survival by acting as the arms which bring food to the mouth and propellers which moves it rapidly from place to place.( MG 2016) Rotifers are ecologically important to aquatic systems . Two of the main ways they help is by aiding in the natural purification of water and feeding on algae. (MG 2016)

Description

Lake Proctor is a reservoirs located on the upper reaches of the Leon River (Texas Parks and Wildlife Foundation). Lake Proctor is located in Comanche county (Texas Parks and Wildlife Foundation). Water samples were collected on November 1, 2016. The organisms examined under a microscope for Lake Proctor were found in the sample that was taken from a very turbid and shallow edge of the lake. During the time of collection, the boat was being anchored on shore so there was more disturbance in the water than usual. The sample analysis for this location was perfumed on November 8, 2016 in a research lab located at Tarleton State University. The organism exposed during the sample analysis was long, slender, transparent, almost ridged looking, pointed on the end and collapsed in on itself as it moved. After researching the organisms’ morphology, it was eventually identified as a rotifer in the class Bdellocidea. There are about 460 known species of the Subclass Bdelloidea, found in a variety of habitats around the world, with very little recorded regarding the ecology and morphology of the species in this class, therefore, it was unable to be identified down to the species level (Moreira, 2016). Most bdelloid rotifers are found in profusion in freshwater bodies and in permanently or periodically damp places and has the ability to live in any aquatic habitat, even a short-lived one, because these rotifers can survive dehydration by entering into a dormant state called anydrobiosis (Moreira, 2016).

Description

Collected from littoral water in Duck Pond near the Colorado River.

Keratella is a type of Rotifer that is shaped like a cup with spines facing forward our of its mouth and one tail-like spine. Keratella are extremely small and can't be seen without a microscope. Keratella is predominately translucent and consumes by filter feeding. When keratella move they appear to be floating or gliding through water with its ciliated corona.

Keratella can be found all around the world in most types of aquatic habitats. Keratella can eat many types of food but mainly feed on phytoplankton. Keratella also serve as a food source for other organisms.

Description from Wikipedia

The rotifers (Rotifera, commonly called wheel animals) make up a phylum of microscopic and near-microscopic pseudocoelomate animals. They were first described by Rev. John Harris in 1696, and other forms were described by Anton van Leeuwenhoek in 1703. Most rotifers are around 0.1–0.5 mm long (although their size can range from 50 μm to over 2 millimeters), and are common in freshwater environments throughout the world with a few saltwater species; for example, those of genus Synchaeta. Some...
