Whales are mammals ; see relevant link for additional information .
Whales have pelvic bones because millions of years ago, they were land animals, but as they evolved, they no longer needed their pelvis because over time they lost their need for legs. So now their pelvis and legs are vestigial, meaning they no longer serve their original purpose. They just kept the trait. As for fish, they never had legs, so no need for a pelvis.
The number of bones that a fish has is dependent upon the type of fish. Some fish do not have any bones, while other fish have hundreds of bones.
human s pelvic region is strong & robust frog have no ribs rabits pelvic region hung down low on the back with its limb parallel to ground in cat pelvic girdle gives strength n stability in fish pelvic girle find as pelvic fins
Yes, fish have bones. Some fish have cartilige (e.g sharks and rays)
Fish have bones. Thorns are found on plants like roses and weeds.
It's so important because it can help the fish have BALANCE to swim in the water i think they use the Pelvic fin so the can swim aswell from predetors... --ShAnNa RiMpOlA--
yes
feces. In their feces is fish bones and stuff.
Fish do not have "pelvic girdles" per se. Land animals in large majority have skeletal structures in their hips known as pelvic bones. In humans, men have a narrow pelvic size and women have a wider pelvic size. This is because women bear babies. The circular shape of these pelvic bones are referred to as the "pelvic girdle". Fish, however, don't have hip bones. Living in the water has eliminated the need for the extra physical support those bones would give during pregnancy. Since fish range in size from near-microscopic up to the immense whale shark, the equivalent to the pelvic area would vary greatly in size. Mammals too, range widely in size so comparison is difficult without a more specific question.
Because they are mammals not fish
All fish and some whales i just dont know!!
Because fishes have gills whales dont.
no, because they dont chew they swallow
fish they put it in fish food for salt water fish.
