Why is numbness experienced after eating puffer fish?
TTX (the poison in pufferfish) inhibits neurons that transmit sensory information to the brain. Since TTX prevents the generation of action potentials in sensory nerves, the ability of the neurons to transmit sensory information will be inhibited. This loss of sensory information would be experienced as a "numbness" in areas exposed to the toxin.
How do bony fish regulate temperature?
Since most fish are bony this would count for all cold-blooded fish (minus cartilaginous ones such as the shark or sting ray). Because fish are cold-blooded or exothermic they change body temperature according to the water temperature. In order to regulate their temperature they either move to warmer or colder water, or they change the blood flow to blood vessels near the surface of there skin or fins and use this to change the rate in which they change color. Since the colder the water the slower the animal (in the case of cold blooded animals) many fish live in warmer waters, but there are still fish that live as far up as the arctic or as far down as the coast of Antarctica .

What are some patterns of behavior for Mexican walking fish?
The axolotl is carnivore which eats small prays like worms or insects.
The axolotl's body can grow up to 30 cm.
The axolotl can regenerate, for example, if a limb is lost it can grow back in 8 weeks.
The axolotl contains poison glands, so any predator must think twice on eating this little salamander.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.
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.

Are there more then 20000 Species of fish or less than 20000?
Yes there is more! There is 27,000 species of fish! That is amazing.
Nope. Goldfish are Cold Blooded, which allows them to survive during the winter in nearly frozen lakes. They do prefer relatively warm water and their metabolism will slow down if they are in cold water long enough.
Most indoor tank temperatures are just fine for fish. A water heater can be used during winter or if the room temperature is especially chilly.

Where do you have to aim to hit the fish for spear fishing?
What to remember when spear fishing:
- When light passes through air, it travels in a straight line. However, when light passes from the air to the water, or water to the air, it is bent, or refracted. When light passes through any two substances of different densities, the light changes speed and is bent.
- We think we see exactly where the fish is. Actually, the fish is lower than we perceive. It appears closer to the surface than it actually is. If you put the tip of your spear in the water, it will seem bent.
- The secret of spearing fish is to know how much below the image to aim the spear. The fish isn't where you think it is!
- The greater the angle (from the vertical) the fish is viewed from, the more the light is bent. Spearing from directly above, the fish will appear to be in the same place, but will appear bigger and closer to the surface than it really is.
