Mazes for Small Aquatic Animals
The American Journal of Psychology, 1956The construction of a small, inexpensive, water-tight maze with uniform channels has offered a problem to investigators of the behavior of the protozoans and other small aquatic animals. Mazes etched in glass have gross irregularities in the channels that are detrimental especially for unicellular animals.

Cholinesterases of Aquatic Animals
1993Cholinesterases (ChE) were discovered in 1906 (Hunt and Taveaux 1906). In 1943, a hypothesis was advanced that two types of enzymes exist, referred to as “true cholinesterases” and “pseudocholinesterases.” According to the latest nomenclature, they correspond to two groups: acetylcholinesterase-acetylcholine-acetylhydrolase [EC 3.1.1.7 ...

: Carotenoids are yellow to red isoprenoid polyene pigments; approximately 650 carotenoids are known from bacteria, fungi, plants and animals. They occur not only as free forms but also as esters, glycosides, sulfates and carotenoproteins. A recent discovery of antitumor activity in carotenoids, such as vitamin A and β-carotene, has brought attention ...

Sponges are classified as the simplest metazoan phylum of the animal kingdom. They have a hollow circular body that filters out the water of the environment, retaining the food. Spongin is a protein that is the main part of the body and a “skeleton” of spikes consisting of calcium carbonate and silica hardens it.
