- Multicellular
- Eukaryotic animals cells
- Tissues make up organs which form complex system
- Normally are symmetrical, radial or bilateral
- Heterotrophic: they can be herbivorous,carnivorous or omnivorous
- Nervous system and sense organs
- Reproduce sexually or asexually
1.2
¿What are the fish?
Fish are primarily aquatic vertebrate animals, generally hectothermic and breathe through gills. They are usually covered by scales, and are endowed with fins that allow their continuous movement in aquatic environments, and gills, with which they capture oxygen dissolved in water.
1.3 Characteristics about the fish
The absence of eyelids in the eyes, which are therefore always open They lack an outer ear, but they are capable of perceiving sounds, since they have an inner ear. The basic difference with tetrapods is the gills

1.6 Digestive system
Although all species of fish have mouths, not all have developed jaws (an example of this is the agnate). In the case of species that did develop jaws, this allowed them access to a much wider variety of foods, including plants and other organisms.
In fish, as the food is ingested through the mouth, it is broken down in the stomach. Organs like the liver and pancreas add digestive enzymes. Nutrient absorption takes place through the intestine.
1.7 Habitat
Fish live both in the sea and in fresh waters (rivers and lakes), from the shallow waters to the depths, where the darkness is total. The existence of fish with light-producing (luminescent) organs has been found in these regions.
Vital functions
"The second largest group is herbivorous fish that obtain their nutrients from foods of plant origin. In this case it can be both plants and algae, depending on the depth at which these fish live.An exaple is cat fish .
Carnivorous fish: they feed on other smaller fish but also on a large number of invertebrates as examples of carnivorous fish are sharks and tunas.
Omnivore fish: in the feeding of fish a large number of fish are omnivores since they can feed on both vegetables and animals, depending on the occasion.Example of omnivore fish there are many, one of the most surprising being the piranhas.
There is a type of feeding of fish practically exclusive to these animals within the world of vertebrates that is known as filtration. As its name indicates, the process consists of the ingestion of large amounts of water and the subsequent filtration of it to obtain food from small microscopic or very small organisms that can inhabit the water.
A very typical example is found in animals such as sardines and anchovies.
Detritivores feed on the waste of other fish an example are coridoras .
Respiration
Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat).
Circulation and excretion
Circulation
Excretion
To maintain their water balance, marine fish drink large amounts of seawater, retain most of the water, and excrete salt. Marine fish can excrete salt by groups of special cells in the gills.
Fish have a closed-loop circulatory system. The heart pumps blood in a single circuit throughout the body. In most fish, the heart consists of four parts, including two chambers and an inlet and outlet. Blood flows to the gills for oxygenation.
8.Reproduction
What kind of reproduction do the fish have?the fish ?
Most of the fish present oviparous reproduction, that is, expelling eggs to the outside. Although there are also viviparous fish, as is the case with some sharks and some freshwater fish, in which the embryo develops inside the female's uterus.
Sense organs
Chemoreceptor
Mechanoreceptors
Photoreceptor
Inside the nasal cavity is the olfactory epithelium with sensory cells that detect molecules dissolved in water.
The fish have simple eyes that only detect light from under the sea.
In fish,vibration or movement receptors are located on the lateral line;The lateral line is The lateral line is a sensory organ of some of the marine animals. Used to detect movement and vibrations of the surrounding water.
They can swallow and taste water to complement the perceived smell and on the other hand they not only have taste buds on the tongue, like us, but in the whole mouth and also outside of it, the most common are usually on the lips, whiskers.
7. Interaction:effectors
¿What is the locomotor system?
The locomotor system is made up of bones, muscles, tendons and ligaments.There are two type of locomotor system:The locomotor system in invertebrates and the locomotor system in vertebrates.
¿What type of locomotor system have the fish?
The fish have the locomotor system in vertebrates In order to move in the best way in the aquatic environment (mainly), the fish have developed a series of fins, since the contraction and relaxation of the muscles causes movement in the extremities.
