Why can amphibians and reptiles stay underwater longer than birds and most mammals?
Mammals like humans are not very good at staying underwater but whales and porpoises are remarkable at staying under water. Equally some birds like cormorants and penguins are well adapted to being underwater and can stay there for a long time.
There are several reasons why amphibians and reptiles can stay underwater for a long time. One is because they are poikilotherms which means that they do not waste energy trying to keep warm. This will save a lot of oxygen. They may also be adapted to be able to have high concentrations of waste materials like carbonic acid and lactic acid in their blood without having any ill-effects. Most animals that go underwater also have strategies where metabolic function slows down. As this is temperature dependent and amphibians and reptiles can survive getting much colder they can slow right down and conserve energy. Some reptiles are also adapted to have wrinkly skin through which they can absorb oxygen from the water that can mean they don't need to go to the surface very much at all.

What is the smallest fish int he world?
Scientists have discovered the smallest known fish in the world. Found in swamps on Sumatra, Paedocyprisis only 7.9mm long. Unfortunately, their diverse habitat, home to other species that aren't found anywhere else, is threatened by logging, agriculture, and the spread of cities. From London's Natural History Museum: 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.
'This is one of the strangest fish that I've seen in my whole career', said Ralf Britz, zoologist at the Natural History Museum.
'It's tiny, it lives in acid and it has these bizarre grasping fins. I hope we'll have time to find out more about them before their habitat disappears completely.'
When did star fish first appear on earth?
Fossil records suggest that starfish came about in the Cambrian period. This was about 500 to 570 million years ago. This is part of the Cambrian burst, a period of time when there was sudden explosion complex lifeforms on the planet.
The Kalinagos practised fishing/caught fish by shooting the fish that came to the surface with bows and arrows. They also used nets,traps and fishing lines with hooks made of shell.
Why are crustaceans called shell fish?
Crayfish belong to phylum arthropoda because they, like all arthropods, are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages. Crustaceans like crayfish, lobsters, and crabs are all arthropods.

That would all depend on the language you use and what you mean by a 'Fish Home'. Some fish are territorial in their 'habitat' and defend a 'territory' but most fish do not have a home as such. If however you mean what do people call a container into which they place and keep fish, then in English that would commonly be called a 'Fish Bowl' 'Fish Tank' or 'Aquarium'.
