The biology of zooplanktons.

1. Animal plankton; floating animal organisms collectively.
2. A small animal organism present in natural waters.
3. Microscopic animals that move passively in aquatic ecosystems; such as, protozoans.
4. Microscopic drifting animal life much of which lives on or near the surface of water but some are at greater depths.

The zoologist studies the nutritional requirements and efficiencies of food conversion of marine animals (zooplankters) feeding on marine phytoplankters or on other small animals.

These tiny animals consist of rotifers, copepods, and krill, and microorganisms once classified as animals; such as, dinoflagellates and other protozoans.

To the zooplankton belong the protozoa, the sea anemones, the corals, and the incredibly shaped jellyfishes.

Zooplankton are animals that are kept in suspension by water turbulence and dispersed more by such water movements than by their own efforts. The majority are small crustaceans (copepods, krill), arrowworms, and gelatinous creatures that feed primarily on phytoplankton.

Living substance which depends on the products of other living organisms for nutritive material.

1. The process of surgically grafting tissue from a lower animal onto the human body.
2. The surgical transplantation of an animal organ, e.g., a pig’s heart, into a human body.

A series of projected images of slides placed on a large disk onto a screen. Eadweard Muybridge spent most of 1881-1882 in Paris and London exhibiting the zoopraxiscope and lecturing on animal motion.

The zoopraxiscope (pronounced ZOH uh PRAKS uh skohp), invented by British photographer Eadweard Muybridge and first shown in 1879, was a primitive version of later motion picture devices which worked by showing a sequence of still photographs in rapid succession. Muybridge, perhaps best known today for his sequence of photographs of a race horse in motion (which proved for the first time that at top speed all feet leave the ground), studied photography in the early 1860s with daguerrotypist Silas Selleck and later achieved recognition for his photographs of the Yosemite Valley and other scenes of the American Far West.

The zoopraxiscope emerged out of his studies of motion as shown in sequences of still photographs. His eleven-volume work, Animal Locomotion, published in 1887, contained over 100,000 photographs. In 1893, he lectured at "Zoopraxigraphical Hall" at the World's Columbian Exposition in Chicago.

The zoopraxiscope, along with the zoetrope and the thaumatrope, could be considered forerunners of today's motion display technologies (including the animated GIF and video display technologies such as streaming video), all of which create an effect of motion by presenting discrete but closely-related images one after the other.
