About 20cm long, 1mm wide. Firm and dry to touch. Will add video later.
Swimming in water we observed a 10cm long, very thin (probably no more than 1mm thick), worm like creature. It swam in a snake like fashion and came up for air every 30 sec or so. Head was very small and could not make out much
Very thin worm type thing, just thicker than a pin, approx 8cm long. Seen 'swimming' swaying under water. Was not sure it it was even alive or not and too small to make out any features. Looks like an old Erica flower stuck to it. Picked it up and it was a still, put it back in water and it swam against current, like an eel type movement.
Found in slow moving stream in forest on Mariepskop
Mermis nigrescens (Nematoda: Mermithidae) a parasitic nematode of the European Earwig Forficula auricularia (Dermaptera: Forficulidae). Image is of an adult female, the sex evident by the presence of the brownish string of eggs within the transparent body. Following substantial rain the female seeks a plant high point and lays its eggs on leaf tips. Species was identified through genetic analysis for a published paper titled: Morphological and molecular characterisation of Mermis nigrescens Dujardin, 1842 (Nematoda: Mermithidae) parasitising the European earwig (Dermaptera : Forficulidae) in New Zealand.
One individual on a clover leaf (found on the ground). It is are maybe 0.2 or 0.4mm wide. Note it is dark on top and light underneath. Moved in a coiling motion, writhing about and making many circles.
These were living in shallow puddles on a bare spot in our yard. They infect beetles and other insects but are harmless to humans!
Gefunden in der Regentonne beim Ablassen des Wassers. Länge gesamt ca. 10 cm
