Cyrtobagous salviniae is a species of weevil known as the salvinia weevil. It is used as an agent of biological pest control against the noxious aquatic plant giant salvinia (Salvinia molesta). The adult weevil is about 2 millimeters long. It is brown in color during its first few days of adult life and soon turns shiny black. The female lays over 300 eggs one by one in the lower leaves and rhizomes of the salvinia plant. The larva is white in color and about 4 millimeters long. It burrows through rhizomes and feeds voraciously on new buds, warping and stunting the plant until it eventually sinks. The larva pupates underwater amongst the rhizomes of the plants in a cocoon it weaves from root hairs. Adults also damage the buds and leaves of the plant during feeding, but do less damage than the larvae. This weevil is native to South America. It has been introduced to areas where giant salvinia is a problem. Early experimental successes occurred in parts of Africa and southeast Asia, and the weevil is now established in the southeastern United States and parts of Australia, along with the moth S. multiplicalis, as biological control for invasive water weeds. In many cases the weevil has cleared salvina infestations by 90% or more in under one year. Entire waterways have been unclogged by the weevil's feeding. It also feeds upon Salvinia minima, a similar but less dramatic aquatic weed. It is similar to the closely related Cyrtobagous singularis, but the two weevil species have slightly different ecologies and C. singularis is generally an ineffective substitute for C. salviniae.

Cyrtochiloides, a genus of orchids described in 2001 by Norris H. Williams and Mark W. Chase, is designed to provide a small group of Neotropical epiphytes, previously included under a broad concept of Oncidium Sw., with a new, more accurate identity based on DNA. Cyrtochiloides is akin to the mainly South American Cyrtochilum Kunth, a genus described in 1815. After having found its species scattered in Oncidium and several other genera, recently Cyrtochilum received notable acceptance by botanists, primarily based on the molecular discoveries made by Williams and Chase, as well as morphological analyses carried out by Stig Dalström. DNA samples illustrate that Oncidium ochmatochilum Rchb.f. and several other species have only a diluted concection with the core of the Oncidium species. This new genus forms part of a well-supported clade including Otoglossum (Schltr.) Garay & Dunsterville, Cyrtochilum, the Andean group of Caucaea Schltr. (also previously retained under Oncidium as the section Cucullata), and Miltoniopsis God.-Leb.

Cyrtochiloides ochmatochila is a species of orchid. The genus Cyrtochiloides N.H.Williams & M.W.Chase (2001) comprises a small group of Neotropical epiphytes, previously included under a broad concept of Oncidium Sw., with a new, more accurate identity based on DNA. Cyrtochiloides is akin to the mainly South American Cyrtochilum Kunth (1815). After having found its species scattered in Oncidium and several other genera, recently Cyrtochilum received notable acceptance by botanists, primarily based on the molecular discoveries made by Williams and Chase, as well as morphological analyses carried out by Stig Dalström. DNA samples illustrate that Oncidium ochmatochilum Rchb.f. and several other species have only a diluted connection with the core species of Oncidium. This new genus forms part of a well-supported clade including Otoglossum (Schltr.) Garay & Dunsterville, Cyrtochilum, the Andean group of Caucaea Schltr. (also previously retained under Oncidium as the section Cucullata), and Miltoniopsis God.-Leb.

Cyrtogomphoceras is a genus of nautiloid cephalopods, recognized by its large breviconic shell with a notable endogastric curvature. The shell is fusiform in profile, reaching maximum width at or near the base of body chamber, which narrows toward the aperture. The siphuncle is large and slightly removed from the ventral side, that with the concave longitudinal profile. Siphuncle segments are short, as are chambers; septal necks recurved, connecting rings thick, bullettes at the apical end of the rings swollen. Cameral deposits are lacking. Cyrtogomphoceras seems to be derived from Strandoceras by a reduction in the degree of endogastric curvature and may have given rise to Landeroceras by a further evolutionary straightening of the shell. Cyrtogomphoceras, named by Foeste, 1924, has been found in middle and upper Ordovician beds in North America and Greenland. Fossils identified as such have also been found in the Silurian of Estonia. The type species is Oncoceras magnun Whiteaves 1890.

Cyrtobagous salviniae is a species of weevil known as the salvinia weevil. It is used as an agent of biological pest control against the noxious aquatic plant giant salvinia (Salvinia molesta). The adult weevil is about 2 millimeters long. It is brown in color during its first few days of adult life and soon turns shiny black. The female lays over 300 eggs one by one in the lower leaves and rhizomes of the salvinia plant. The larva is white in color and about 4 millimeters long. It burrows through rhizomes and feeds voraciously on new buds, warping and stunting the plant until it eventually sinks. The larva pupates underwater amongst the rhizomes of the plants in a cocoon it weaves from root hairs. Adults also damage the buds and leaves of the plant during feeding, but do less damage than

Cyrtocycloceras is a genus of orthocerids from the Middle Silurian of Europe included in the Paraphragmitidae. The shell, or conch, of Cyrtocycloceras is a moderately expanding annulated exogastric cyrtocone, with curvature like that of a rocking chair rocker. Annulations, encircling ribs, are close spaced and transverse and the surface is transversely striated. Calocyrtoceras from the Middle Silurian of both Europe and North America is striated both transversely and longitudinally while Gaspocyrtoceras is striated only longitudinally. Moreover the annulations on Calocyrtoceras and Gaspocyrtoceras tend to be thicker and further apart than on Cyrtocycloceras.
