Big fishes tale see more
This "fish tale" is generally a nice story about a father who tells tall tales for years to everyone and has a son who has resented those stories, thinking his father was nothing but hot air. The big pluses for this film were the colorful scenes and the fact that is was simply a nice story. Since this is a Tim Burton film, it's no surprise that the visuals are so entertaining but it is a surprise that the story isn't a dark one. I guess that disappointed a lot of his fans but thought it was a Irefreshing change of pace from him, and I appreciated his effort here. It's the kind of movie many folks wish they made more of today.
Human Friends Fishes on Sea Dolphins
Dolphins are social animals, living in so called schools of up to a dozen animals. In places with high abundance of food, schools can join temporarily forming aggregations of over 1000 dolphins. The individuals communicate using a variety of klicks, whistles and other vocalizations. They also use ultrasonic sounds for echolocation.Membership in schools is not rigid, interchange is common. However, the animals can establish strong bonds between each other. This leads to them staying with injured or ill fellows for support.Dolphins are predators, chasing their prey at high speed. The dentition is adapted to the animals they hunt: Species with long beaks and many teeth forage on fish, whereas short beaks and lesser tooth count are linked to catching squid. Some dolphins may take crustaceans. Usually, the prey is swallowed as a whole.
Most Expensive Aquarium Fish - Platinum Arowana = $80,000
The most expensive aquarium fish for your designer aquarium would be the rare platinum Arowana. This 15" platinum Arowana is owned by the Aro Dynasty, Singapore based breeder of fishes. Wondering what makes this platinum Arowana so pricey? There is a special reason for it. The Platinum Arowana has to be perfectly white without any flecks of other color anywhere else on its body to become one of the most expensive aquarium fish in the world.
What makes this the most expensive aquarium fish in the world is that platinum Arowana has the rarest white color which is a result of some kind of natural mutation. Arowanas generally are not so costly, but this aquatic exception is unique in its own way. This fish is of the species Osteoglossum that are mostly found in South America.

World's smallest fish
Scientists have discovered a fish living in forest swamps on the Indonesian island of Sumatra that is only 7.9mm long.
The species of fish belongs to the carp family and is called Paedocypris progenetica . It is the world's smallest vertebrate or backboned animal.

Living in acid
The tiny, see-through Paedocypris fish have the appearance of larvae and have a reduced head skeleton, which leaves the brain unprotected by bone.
They live in dark tea-coloured waters with an acidity of pH3, which is at least 100 times more acidic than rainwater.

Fish Change the Different Colours
Some fishes cannot change colour. Examples include many of the uniformly dark-pigmented and some unpigmented cave fishes.
Many species of fishes however can change colour. The changes can be slow or fast. Slow changes of colour (eg breeding colouration) are generally under the control of hormones and are usually semi-permanent.
Rapid colour changes (eg stress responses) are largely under control of the nervous system although hormones may also be involved. The colour of fishes can also vary with the seasons, between day and night and even with changes in habitat and food.
There are two kinds
