Caenorhabditis castelli is a species of Caenorhabditis nematodes, a member of the same genus as the model organism Caenorhabditis elegans . Within this genus, C. castelli belongs to the Drosophilae super-group, and Angaria group. This species is a close relative of C. angaria [2] and was referred to as "C. sp. 12" prior to 2014. [3] C. castelli was discovered from rotting Micropholis cayennensis fruit in the Nouragues Nature Reserve of tropical French Guiana in 2008. [2] It is one of the rarest species found in French Guiana. [4]
The mean body length of adult female C. castelli was measured to be 1212.24 μm and for adult males, 827.61 μm, which is comparable to the average male body size of the model organism C. elegans (824.74 μm). [5]
The spicules of C. castelli males possess a short, stout, evenly curved, complex morphology, similar to other Caenorhabditis species within the Angaria and Drosophila groups. [2]
Like most species of Caenorhabditis, C. castelli demonstrates a gonochoristic, or male-female, mode of reproduction, as opposed to C. elegans and C. briggsae which demonstrate an androdioecious mode of reproduction, such that populations primarily include self-fertile hermaphrodites with more rare males. [2] Notably, C. castelli mates in a spiral mating style, where the male wraps around the female with its posterior end, [6] [7] a characteristic shared with other species in the Angaria group. [2]
C. castelli males contain larger sperm cells (28.81 μm2) on average compared to hermaphroditic Caenorhabditis species like C. elegans (19.55 μm2), C. briggsae (18.65 μm2) and C. tropicalis (19.81 μm2). [5]
In the lab, C. castelli can hybridize with C. angaria to produce sterile females and slow growing males. [1] Hybridization of C. castelli with C. quiockensis was attempted, but the two species failed to hybridize. [7]
Caenorhabditis is a genus of nematodes which live in bacteria-rich environments like compost piles, decaying dead animals and rotting fruit. The name comes from Greek: caeno- ; rhabditis = rod-like.
Caenorhabditis brenneri is a small nematode, closely related to the model organism Caenorhabditis elegans. Its genome is being sequenced by Washington University in St. Louis Genome Sequencing Center. This species has previously been referred to as C. sp 4 and Caenorhabditis sp. CB5161, but was recently formally described and given its scientific name. This name is in honor of Sydney Brenner, recognizing his pioneering role in starting active research in the field of C. elegans biology and development.
The Rhabditidae are a family of nematodes which includes the model organism Caenorhabditis elegans.
Caenorhabditis remanei is a species of nematode found in North America and Europe, and likely lives throughout the temperate world. Several strains have been developed in the laboratory.
Caenorhabditis angaria is a small nematode, in the same genus as the model organism Caenorhabditis elegans. The name is from the Latin after the tendency to ride weevils. Prior to 2011, the species was referred to as C. sp. 2, C. sp. 3, and C. sp. PS1010. Its genome was sequenced at the California Institute of Technology in 2010. This species is gonochoristic. It has distinct morphology and behavior compared to C. elegans; notably, C. angaria males exhibit a spiral mating behavior. Its divergence from C. elegans is similar to the distance between humans and fish. C. castelli is its closest relative, and the two species can produce F1 hybrids.
Caenorhabditis tropicalis is a species of Caenorhabditis nematodes, belonging to the Elegans super-group and Elegans group within the genus. It is a close relative of C. wallacei.C. tropicalis is collected frequently in tropical South America, Caribbean islands, and various islands in the Indian and Pacific Oceans from rotting fruit, flowers and stems. C. tropicalis was referred to as "C. sp. 11" prior to 2014.
Caenorhabditis afra is a species of nematodes in the genus Caenorhabditis. This gonochoristic (male-female) species was isolated by Matthias Herrmann in Begoro, Ghana, Africa in 2007. Its genome is being sequenced at McDonnell Genome Institute at Washington University School of Medicine.
Caenorhabditis plicata is a species of nematodes in the genus Caenorhabditis. It was described on carrion in Germany and is phoretic on carrion visiting beetles.
Caenorhabditis monodelphis is a species of nematodes in the genus Caenorhabditis. It was first collected by J. Raschka in Berlin, Germany in 2001. A second isolate was collected from Norway. It is a free-living species found in galleries inside of the fungus Ganoderma applanatum (Polyporaceae) which grew on the stump of a tree a few centimeters above ground. It is phoretic on beetles of the species Cis castaneus.
Caenorhabditis portoensis is a species of nematode in the genus Caenorhabditis. First wild isolate sample was found on a rotting apple in Portugal.
Caenorhabditis nigoni is a male-female species in the Elegans group of the genus Caenorhabditis, first identified and described as "Caenorhabditis species 9" or "C. sp. 9" before being renamed as "C. nigoni". The specific epithet is a tribute to Victor Nigon who first studied Caenorhabditis elegans in the laboratory with Ellsworth Dougherty in the 1940s. Isolates come from the Democratic Republic of the Congo and Kerala, India.
Caenorhabditis latens is a species of nematode. Prior to 2014, it was referred to as Caenorhabditis sp. 23. The reference strain VX88 was isolated from soil near a lotus pond, and strain VX85 was isolated from soil under rotten grass in Juifeng Village, Wuhan City, Hubei Province, China.
Caenorhabditis guadeloupensis is a species of nematodes, in the same genus as the model organism Caenorhabditis elegans. This species was collected from rotten Heliconia flowers on the Soufrière Forest trail, in Guadeloupe, France.
Caenorhabditis imperialis is a species of nematodes in the genus Caenorhabditis. Prior to 2014, it was referred to as C. sp. 14. The type isolate was collected in Mo'orea, French Polynesia, and other isolates were collected in Guadeloupe.

Caenorhabditis sinica, is a species of Caenorhabditis nematodes, belonging to the Elegans super-group and Elegans group within the genus. It is closely related to several species isolated from the lands adjacent to the Indian and Pacific Oceans, as well as to C. briggsae and C. nigoni. The species was known as “C. sp. 5” prior to 2014. C. sinica is known for having very high genetic diversity in its genome. Like other Caenorhabditis species, C. sinica is a ~1mm long roundworm with a transparent cuticle and that eats bacteria. Wild isolate strains of C. sinica have been collected from various rotting plant tissue substrates in temperate and tropical regions throughout China since its initial isolation in 2005.
