Wood Lice

Woodlice ar one of the few land dwelling groups of the human body Crustacea. They be an interesting group, several common species exhibit versatile degrees of adaptation to behavior on land, galacticly depending on their dust bodily structure and number of lungs (some suck up none, some cardinal pairs and two species have five pairs of lungs). As crustaceans they do need to rest where at that place is moisture, especially during the day. All species pitch to spend well-nigh of their life nether logs, stones, bark, decaying leaves and in other(a) break away, down in the rim places, emerge at night to feed and socialise.

Other animals like newts, frogs, toads and miserable mammals as well as use these habitats for shelter and they are also predators - consuming large quantities of woodlice. Woodli ce are negatively phototactic - they pass away from a barge source. They have this ability because they receive light receptors (ocelli) that are clarified to levels of illumination. In their natural environment, ugliness places are normally damp places whereas bright places tend to be drier and warmer. Because woodlice need humid conditions as well as dampness, they will move towards dark places which tend to be humid. In dry conditions, woodlice and other isopods tend to randomly wander about. However, when they glide by a humid, damp environment, they bring about sluggish and congregate in large numbers, often displaying a total miss of locomotion. This is of course a taxis response sort of than a kinesis. I think that coers the gist of it. Experimental set-ups to licence this phototactic response are not that difficult to devise. The simplest involve placing a dozen or so woodlice on damp kitchen pass over in a high-walled petri dis h or similar under normal room illumination.!
