Summary
[edit]| Description |
Afrikaans: Peripatus, 'n interessante dier wat 'n skakel vorm tussen wurms en insekte. Omtrent 20 spesies is bekend, wat voorkom in Suid-Afrika, Australië, Nieu-Seeland, Suid-Amerika en in die Wes-Indiese Eilande. Hulle het 'n lang liggaam soos dié van 'n wurm of ruspe, maar die segmente of partisies is nie uitwendig sigbaar nie. Inwendig is hulle egter duidelik onderskeibaar. Daar is geen onderverdeling tussen borsstuk en agterlyf nie. Die kop dra voelers en kake. Die liggaam is toegerus met kort gelede pote (14 tot 24 pare), soos 'n duisendpootagtige. Soos die myriapode word hulle onder klippe en in verrotte hout aangetref, en voed op insekte endiesmeer. Hul inwendige struktuur is noemenswaardig. Hulle beskik oor een paar lusvormige buise in elke segment van die liggaam, soos dié van wurms, en benewens oor asemhalingsbuise soos dié van insekte en myriapode. Strukturele kenmerke van twee verskillende subkoninkryke van diere word aldus in peripatus verenig. Dis 'n soort ongespesialiseerde oorbruggingsvorm tussen wurms en myriapode, en die myriapode sluit aan by die basale insekte. Peripatus is besonder interessant vir dierkundiges as 'n oorlewende van 'n baie antieke dierefamilie en as 'n skakel tussen die wurms en geleedpotiges.
English: Perip`atus, an interesting animal connecting worms and insects. About 20 species are known, inhabiting South Africa, Australia, New Zealand, South America and the West Indies. They have a long body like a worm or caterpillar, but the segments or joints do not show on the outside. Internally however, they are well-marked. There is no division into thorax and abdomen. The head bears antennæ and jaws. The body is provided with short jointed feet (14 to 24 pairs), like a thousand-legged worm. Like the myriapods, they are found under stones and in rotting wood, and feed on insects and the like. Their internal structure is noteworthy. They possess a pair of looped tubes in each segment of the body, like those of worms, and, in addition, have breathing tubes like those of insects and myriapods. Structural peculiarities of two different subkingdoms of animals unite in peripatus. It is a sort of generalized form bridging the gap between worms and myriapods, and the myriapods connect with the lowest insects. Peripatus is of much interest to zoologists as a survivor of a very ancient family of animals and as a link between the worms and arthropods. |
