### animal | vertebrate | fish:

Carp
* adapt better than most fish species to pollution caused by sewage or agricultural run-off.
* are able to tolerate poorer water quality conditions than more desirable fish
  - notorious for stirring up phosphorous on the bottom of area lakes
  - often consider stupid and easy to catch
  - omnivores, which means they eat plants and animals
  - omnivorous feeders, taking both vegetable and animal matter in their diet
  - omnivorous, meaning the eat about any type of plant and animal mater
  - strong, hard-fighting fish with an uncanny ability to find snags
  - very hardy fish and are also omnivorous
  - wild creatures - they have an instinctive fear of alien shapes, shadows and noises
* do forage on the same food items that sport species do.
* eat clams, zooplankton, insects, crawfish and plants
  - plant and animal material which they stir up by rooting around in the bottom mud
* fill our minds and govern our emotions.
* have no adipose fin, which leaves their undersides unattractively blank
  - scales and are natures garbage disposals for ponds and lakes
* prefer shallow waters with dense macrophyte cover
  - the slower water and requires less oxygen
* provide sport in the dog days of summer.
* segregate into groups in the shallows to spawn.
* tolerate lower oxygen levels, warmer water, and some chemical pollutants better than bass.

Cartilaginous fish
* All cartilaginous fishes are carnivores.
* Many cartilaginous fish have powerful jaws.
* Most cartilaginous fish have bones
  - cartilage bones
  - cartilages
  - fins
  - flexible skeletons
  - organs
  - sense organs
* are fish.
* have a skeleton that is made of cartilage instead of bone
  - rows of teeth that grow throughout life
  - skeletons made of cartilage
* includes the sharks , skates and rays.
* is fish
* reproduce partly oviparous, partly viviparous.
* use urea to elevate the osmotic concentration of their tissues.

Catadromous fish
* have a migratory pattern opposite that of salmon.
* live in freshwater, but travel to the high-salinity ocean waters to spawn.
* migrate from freshwater environments to the ocean to spawn.

Cave fish
* are long and skinny.
* provide a model system for exploring the genetic basis of regressive evolution.

Chimaera
* are almost scaleless, with a body resembling a rat
  - formed from at least two fertilized eggs or early embryos fused together
* have smooth skin that lacks scales.
+ Chimaera (genetics): Developmental biology :: Biological reproduction
  * If the different cells have come from the 'same' zygote, the organism is called a mosaic. Chimaeras are formed from at least two fertilized eggs or early embryos fused together. Each population of cells keeps its own character and the resulting organism is a mixture of tissues. Chimaeras are typically seen in animals.

Cleaner fish
* cause predators to reduce aggression toward bystanders at cleaning stations.
* drives local fish diversity on coral reefs.

### animal | vertebrate | fish:

Clown fish
* All clown fish are born male and develop female reproductive organs when needed
* Most clown fish develop female organs
* Most clown fish eat anemones
  - grow to size
* Most clown fish have bright orange skin
* Some clown fish have stripes.
* are an example of a bony fish
  - between two and five inches long
  - omnivorous animals meaning that they eat both plants and animals
  - popular tropical aquarium fishes
* are the inhabitants of tropical, subtropical and coastal waters including Mediterranean
  - most likely to host in a carpet anemone as compared to all other anemones
* eat a wide range of food such as algae, plankton, molluscs and small crustaceans
* find most of their food by mooching off the anemone.
  - hearts
* live in anemones and plants and they are poisonous to surrounding fish
  - on the ocean floor
* use the sea anemone for shelter.
