Scanning electron micrographs of some nematodes
|
|
Anterior and posterior ends of Cervidellus spitzbergensis seen through a scanning electron microscope (SEM). The six lips are divided into several parts and the 'labial probolae' look like small antlers in this species. |
|
Anterior end of Acrobeloides nanus. This is probably one of the most common invertebrates in the world. The species can be found on all continents, including the Subantarctic Islands. It thrives in Swedish forest and arable soils, where the numbers may reach well above one million individuals per square metre. |
|
Anterior end of Eucephalobus mucronatus. This species is found in e.g. Swedish arable soil and has six pointed lips.
|
|
Anterior end of Acrobelophis minimus, which is found in i.a. Swedish arable soil. The 'labial probolae' look like tuning forks in this species. |
|
Anterior end of Acrobeles ciliatus. This species has a world wide distribution in sandy soils. The pictured animal is from Sweden. The lips and 'labial probolae' are komplex and fringed with long tines. |
|
Anterior end of Acrolobus emarginatus. This species can be found at many places and also in Swedish arable soil. The six lips are large and leaf-like. |
|
|
Anterior end of Acromoldavicus skrjabini, which was originally found in Moldavia (in the former USSR). It has later also been recorded from Greece, Spain, Hungary and Iran. The animal on the picture is from the Greek island Samos. The lips are very komplex in this species. |
|
Anterior end of Metateratocephalus crassidens, which is common in Swedish forest soils and mires together with the two species Teratocephalus costatus and Teratocephalus lirellus. The pictured animals were found on Spitzbergen. |
|
Anterior end of Plectus rhizophilus. Species of Plectus are common in Swedish forest soils and bogs. The animal on the picture was found on the Subantarctic island South Georgia. The four appendages are sensory organs and the large opening leads to a kind of olfactory organ - there is a similar opening on the opposite side of the anterior end. |
