"Ctenophora" Natural Recordings by Native Speakers
Ctenophora refers to a phylum of marine animals commonly known as comb jellies. They are characterized by the presence of cilia (small hair-like structures) on their bodies that they use to swim. Ctenophores are usually transparent, soft-bodied animals that range in size from a few millimeters to several centimeters in length. They are found in oceans all over the world and are an important part of the marine food chain, serving as both predators and prey for other animals.
Usage Examples for "Ctenophora"
Ctenocyst is a type of fossilized marine animal, specifically a type of extinct echinoderm that dates back to the Cambrian period, around 541-485 million years ago. Ctenocysts were likely small, pelagic animals that lived in the oceans and were characterized by their ctenoid (comb-like) appendages. They are considered important index fossils, helping scientists to date and correlate rock layers and understand the evolution of marine life during the Cambrian period.
Ctenoid refers to a type of tooth or scale found in fish, characterized by a comb-like pattern of tiny, tooth-like projections used for filtering food particles from the water. In marine biology, the ctenoid system is a key adaptation for some species of fish, such as mullets and pomfrets, allowing them to feed on plankton and small invertebrates. The word is derived from the Greek "kteis" meaning "comb" and "-oid" meaning "resembling".
Ctenoidean refers to a term used in biology, specifically in the study of marine invertebrates. It describes a type of gill or gill-like structure found in some marine animals, particularly in the phylum Ctenophora, which includes comb jellies. Ctenoidean gills are characterized by having tightly packed, hair-like cilia (long, thin hair-like structures) which aid in swimming, respiration, and feeding.
A ctenosaur is a type of lizard that belongs to the family Iguanidae. The name "ctenosaur" comes from the Greek words "ctene", meaning "comb-like", and "saurus", meaning "lizard". This refers to the spiny scales on the ctenosaur's body, which give it a comb-like appearance. Ctenosaurs are found in Central and South America and are also known as "comb-spurred iguanas".
