Zoo hotelma

from Wikipedia, the free encyclopedia

A zoo hotelma (also zootelmal , from ancient Greek ζῷον zoon , "living being, animal" and τέλμα telma , "puddle") is a tiny body of water that is located on an animal and forms the habitat for other, mostly microscopic living beings. As with the Phytotelmata , which are tiny bodies of water in the cavities of plants, a biocenosis of aquatic organisms develops , the species of which mostly only occur in this habitat. This community is called the Zootelmos.

Bricklet with flattened pleopods on the abdomen of the abdomen, which serve as "gill bones"

A well-studied example are the gill chambers of the isopods , which are located in the abdomen of the isopods and are always supplied with water. Here, a special gills fauna has developed from nematodes (Nematoda) of the genus Matthesonema , rotifers of the genus Mniobia and various free-floating or fixed ciliates such. B. the genus Ballodora may exist. The ancestral forms of these animals originally come partly from the sea and partly from the soil of terrestrial habitats. They have specialized in the way of life in the gill chambers of the rural woodlice. During the molting of the host animals, they leave the shed cuticle of the gill space and swim into the newly formed gill space. The stuck eyelash animals have to develop swarming stages.

Another example of a zoo hotelma is the cuckoo's saliva of leafhoppers , in which ciliates live.
