Classification Tree

This is a picture of Koi fish swimming in Blue Pond, Japan.

Classification of koi

There is a classification tree for every species to organize their characteristics and there is one for koi fish. There are 5 subgroups of vertebrates; Amphibians, birds, reptiles, mammals fish. The subgroup that Koi fish falls under is fish, which falls under vertebrates. There are 5 kingdoms; Animal, plant, fungi, monera and protista. Vertebrates falls under the animal kingdom.

These are some pictures of koi fish from the outside and the inside.

Structural Adaptations of Koi fish;

There are many structural characteristics of a koi fish. Koi fish is a vertebrate because it is a type of fish. They are also cold blooded so this means they can not survive in a cold weather because their body temperature is in the same temperature as the environment they are in. so basically they can not generate international body heat. Did you know that koi fish is fully formed when its hatched? They are. For example a frog. They are not fully grown when they hatched. They are tadpoles. But koi is koi as soon as it hatches. They are fully formed.

These are photos of different colored koi fish.

Behavioral adaptations of Koi:

There are just some behavioral characteristics of koi fish. Koi fish lays eggs and does not give live birth. Most importantly, they lay their eggs in water, the safest place for them. In addition, they are omnivores. This means that they eat other animals and plants. These are just some of the behavioral characteristics of koi.

Physical adaptations of Koi fish:

There are so many physical characteristics of Koi fish. They have a layer of shiny skin which makes them obvious under water. Their scale's color is usually silver, white and red which some people might think it's orange but it is actually red. It can grow to be between 2 and 3 feet in length. These are just some of the physical characteristics of koi fish.

Habitat and ecosystems of a koi fish:

The habitat of a koi fish is water. They live in ponds and waters that is not salty because they can't survive in salt water. They swim in a water temperature of between 1 and 32 degrees Celsius, which is between 34 degrees and 90 degrees Fahrenheit. This is the habitat they belong to and the temperature they need to be in.

Migration of koi.

Koi fish can only migrate to a new area by travelling through water such as pond, river, etc. and it is really important that they travel to somewhere that doesn't have salt water in it because salt water makes them blind and kills them. This is how a koi fish migrates from one place to another.

Koi fish positive impacts:

There are many positive and negative impacts that koi fish might have on you and on the environment. Let's start with the positives. The positive impact that koi fish might have on you is that people thinks that it brings luck and success just like a ladybug. That might have an impact on you if you are getting ready for a test. It is also hard to find like a clover so this means it is a combination of the luck that a clover brings and the luck that a ladybug brings. Koi fish also has a positive impact on the environment. When there is a lot of invasive species in an ecosystem, koi fish will eat the invasive species and their eggs, that lives under water, to decrease their population. These are just some of the positive impacts that koi fish has on you and on the environment.

Koi fish negative impacts:

There are also negative impacts that koi fish has on the environment. If people puts too much koi fish in the river so that it can eat the invasive species and it's eggs that is found under water, this time, koi fish's species will increase and this will create a problem by eating endangered species. Their population will increase unusually and this is one of the biggest negative impact koi fish has on the environment.

How to control a Koi fish:

To decrease the population of koi fish that is unusually increased, you can bring a couple of herons in to that ecosystem that will eat the koi fish that will control their population. In addition, you can fish them. If you go to a pond or a river, you can try to fish a koi. It is hard to find them but it's better then noting. Both of these has negative impacts. For example the first one, the herons population might get out of control so that's why you should bring less amount of herons because 1 heron can eat as much as koi fish as they find in 1 day. For the second one, when you try to fish a koi you might accidentally catch an endangered species so when you catch it, before it dies, you should throw them back in before they die. These are just some if the ways how you can control the population of koi fish.
