Adineta vaga DAVIS 1873
Adineta vaga is a very common bdelloid found in many samples from soil and mosses in our region. It often occurs together with other Adineta species like A. steineri. (1)
This species is the first where the (horizontal) transfer fof genes from other organisms has been proven. Evidence for this is given here:
Adineta vaga: head in two different focal planes, ventral view. The ventral side of the head is covered with cilia (ciliary field)which accomplish the moving of the rotifer. left image: bristles at the lamella of the rostrum (yellow arrows). The red arrows point to the cingulum. Right image: the arrows point to the 4 or 5 "U-hooks" on each side that act like rakes by scraping over the surface and gathering bacteria. (1)
Adineta vaga: another specimen, focus plane on the ciliary field and the rakes.(2)
Adineta vaga: same specimen, focus plane on the dorsal side of the head.(2)
Adineta vaga, specimen from Bonampak, Mexico (3)
Adineta vaga, ventral view; focal plane on the ciliary field with 5 U-hooks (3)
Adineta vaga, ventral view; crop of the above image (3)
Adineta vaga, this image from a specimen vital-stained with Neutral Red shows the cuticularized prehensile apparatus with 5 denticles on each side of the rakes. (4)
Adineta vaga, series of 3 optical sections through the head from dorsal to ventral side; the images show the hypodermic cells with their nuclei.
