These are very small found amidst fine gravel. Probably too big to be nematodes. Yellowish gold and translucent.
Type of worm
Found coming out of a small oak log.
Four or five of these were crawling about on the bottom of a small artificial freshwater pond.
Not sure what the host insect would have been, but there was a big dead cockroach Drymaplaneta sp. in the pond.

Poor nematode! He got stuck on some organic matter -- he is really having a bad day! The coordinates for this observation are inaccurate and have to be re-done.
The nematodes /ˈnɛmətoʊdz/ or roundworms constitute the phylum Nematoda. They are a diverse animal phylum inhabiting a very broad range of environments. Nematode species can be difficult to distinguish; and although over 28,000 have been described, of which over 16,000 are parasitic, the total number of nematode species has been estimated to be about 1 million. Unlike cnidarians and flatworms, nematodes have tubular digestive systems with openings at both ends.
