How do ocean fish survive in their habitat?
Fish that live at great depths live virtually the same as fish that live near the surface, with a few differences.
-Fish from deep waters typically lack much color, and some are completely translucent.
-Fish from deeper waters often use bio-luminescence to attract mates and their prey.
The deeper the water is, generally the less oxygen there is dissolved in the water.
To combat this, deep-water fish are often small, and have highly efficient gills. They are also relatively inactive compared to higher level fish.
As far as the pressure is concerned, they are acclimated to it. Similar to the way a diver will acclimate to depths. The oxygen in the blood compresses, nitrogen bubbles form, and basically you are fine until you decide to resurface. You start having problems when you ascend in the water column to rapidly, and the dissolved oxygen in your blood expands by as much as 10x's (this is only from very deep dives mind you), but this is very rarely experienced, as you need to dive to a thousand feet or more to experience that drastic of a change.
Any animal has to ascend slowly through the water column. When a diver dives below 40' for more than 10 minuets he or she has to pause @ 15' to acclimate to the lower pressure for several minuets. Fish have to go through the same process, but when an angler catches a deep water fish, the fish is not allowed to decompress there for it balloons up.
What adaptations does a fish need to swim against a current in a stream?
Basically the same way you walk uphill: by working a little harder.
Answer:
Fish are skilled at swimming (go figure!) and have developed a number of tricks to get upstream in rapid currents.
- The first is quite simple - strategy. The flow in a stream is not consistent. Deep pools are slow, near the shore is slower than the center of the flow, behind rocks are often quiet spots. The fish knows all of these advantageous locations.
- The second is speed. A fish can move quite quickly in water, especially in short bursts. Salmon are often seen bursting out of the water to leap up small waterfalls. For some currents this is enough to move forward for considerable periods before taking a rest. For really swift flows the "strategy" part works in. A fish swims as rapidly as it can from slow moving area to slow moving area. At each rest stop it regains energy to move forward. This same trick lets sailing boats work upstream close to shore in the slow moving currents.
- The third is cooperation. Fish often swim in schools. The front fish do most of the work of overcoming water friction, the other fish can rest and gain energy. The front fish and other fish interchange so that fresh fish can take over the lead as the front fish tire. As a result the schools overall speed increases.
Are angelfish warm blooded or cold blooded?
Most fish do not waste energy keeping themselves warmer than the water around them as this uses a lot of energy. Water is very good at conducting heat. Some larger fish do regulate their body temperature by using counter current arteries and veins and are able to hold it at a higher core temperature than the ambient water. A good example of a fish that can do this is Tuna. The advantage of being able to hold a higher temperature is that chemical reactions can happen more quickly, which makes the tuna a faster predator.

Why is the Mexican walking fish close to extinction?
The Mexican walking fish, also known as the axolotl is a pretty interesting animal. Some facts of the axolotl are: 1. The axolotl is not even a fish, it is an amphibian aquatic salamander, but people call the axolotl a "fish" anyways. 2. The axolotl is carnivore and eats small prays like worms or insects. 3. The axolotl's body can grow up to 30 cm. 4. The axolotl can regenerate, for example, if a limb is lost it can grow back in 8 weeks. 5. The axolotl contains poison glands, so any predator must think twice on eating this little salamander. 6. The axolotl has a weird social behavior. Some domestic axolotls that live in groups often eat each other or eat the other axolotl's egg, so it's preferable to house them individually. 7. The axolotl is nearing extinction. The axolotl mainly was native from Lake Xochimilco and Lake Chalco, but, unfortunately, these lakes have already disappeared or diminished, and most of these species are kept in hatcherys. Take care of the axolotl please.
What body symmetry do fish have?
Swordfish, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
What do a puffer fish do to survive?

You do not need to feed tadpoles I am pretty sure. They eat the gook in the pond. The tadpoles I had we didn't feed. I don't think they have tadpole food. They don't eat fish food. They eat gook under the water and on the sides.
