Not really a whole lot, actually, except for some external differences. Both birds and fish share most of the same organs and cellular structure - they have backbones, hearts, lungs, brains, eyes, etc etc. They move, eat, digest, excrete waste, and are egg-bearing reproducers. Birds, for the most part have feathers and fly, and breath air, while fish have scales, swim in water, and get oxygen from their gills, but other than those three visual differences, birds and fish are very much alike. There's even cellular spots on a fish, for example, that correspond to ears on a bird. And the bones in a fish fin are very very similar to bones in a bird's wing. Now, if you think about it...you'll start to see the connections that all living things have with each other - once you make the jump from single-celled organisms to multi-cellular living things, we all share many many more similarities and characteristics than there are small minor differences between us. We all have an inner fish.
The difference between a mammal heart and a fish heart is....
fish do not have a pulmonary artery they have a dorsal artery
the blood in a fish goes in a circle and mammal blood goes in a figure of eight
one red blood cell moves through 1 time (in a fish) and twice in a mammal
mammals are warm blooded and typically furry and breath in air, while fish on the other hand are cold blooded 'scaly and breath through water with their gills.i hope that helped!
Here is the difference a mammal and a non-mammal. All mammals have an invertebrate or a backbone. All mammals except the platupus gives birth to live babies.
No. There is no fish that carries milk for the offpring. Only marine mamals can do that.
A Fish is a Vertebrate.

It's a fish. A close relative of the pipe fish.
No a dolphin is not a fish. It is a mammal.
mammal
The seahorse.
A cod is neither a reptile nor a mammal. It is a fish; class Osteicthyes
a bass is to fish as horse is to mammal
a mammal mean a animal fish bird insects and reptiles
mammal, reptile, birds, amphibians, and fish
It is a mammal: a warm-blooded, air-breathing animal that nurses its young. All cats are mammals.
The fish is a type of animal though a fish is a type same thing like mammals. confusing but worth it.
If the creature/animal has scales and a fin then it is a fish. Whales have smooth skin so it's a mammal. Dolphins have smooth skin so it's a mammal try asking him. i hear most fish are quite approachable.
It is the biggest animal in the world but it is not a fish, but it's a mammal.
Some are and some aren't. It depends on what type of mammal it is.
A mammal is a warmblooded vertebrate animal of a class that is distinguished by the possession of hair or fur, the secretion of milk by females for the nourishment of the young, and (typically) the birth of live young. This applies to porcupines, so they are mammals.
yes its a type of fish but bigger than an ordanary fish! orso an octopus is a false type of fish!!
Mammal is to lungs as fish is to gills.
