Dolphins are mammals, not fish Unlike fish, who breathe through gills, dolphins breathe air using lungs. Dolphins must make frequent trips to the surface of the water to catch a breath. The blowhole on top of a dolphin’s head acts as a “nose,” making it easy for the dolphin to surface for air.

What does a fish and a dolphin have in common?
Although they are very
different species
, fish and dolphins (mammals) look similar. Their
body shape
is highly streamlined: both have fins and a tail Evolution appears to have repeated itself in producing these two animals that are formed alike.
Why are dolphins and fish analogous?
Dolphins are mammals and fish are not, which means that their evolutionary paths (phylogenies) are quite separate. Dolphins probably adapted to have a similar body plan after returning to an aquatic lifestyle , and therefore this trait is probably analogous. Describe maximum parsimony.

Are fish and dolphins homologous or analogous?
Homologous- Dolphins are mammals and fish are not , thus their evolutionary paths are quite separate. They have similar body shapes because of their similar environment.
Are sharks and dolphins an example of convergent evolution?
We know that dolphins and sharks are not closely related, and they didn’t inherit their similar body shapes from a common ancestor. Their streamlined bodies, dorsal fins and flippers are the result of convergent evolution.
Are mammals and fish related?
Why Do People Think Fish Are Mammals? People may think of fish as mammals because not very long ago scientists believed that many mammals were fish.

Why are sharks and dolphins analogous?
Analogous Structures Sharks and dolphins are similar in construction because they need their “parts” to complete many of the same functions For example, the dorsal fins that are found on both sharks and dolphins are due to convergent evolution; they are not from a common ancestor.
Where did dolphins evolve from?
Dolphins, rather surprisingly, are mammals that evolved from animals that used to live on the land ; in other words they went back to live in the sea.
