Mammals

Well, firstly, all mammals care for their young, while only a few fish do.

Parental care in fish is also more variable in form than in mammals.

All mammals need to nurse from their mothers to survive, so obviously the mother is always involved. In most mammals, mom is the only one to care for her young, while a few mammal mothers get help from fathers, other mothers or their older offspring. However, the mother is always the most important.

In contrast, parental fish have pretty much every system imaginable. 80% of parental fish species only tend the eggs, and leave when the babies are born. Egg-tending can be done by mothers, fathers, or both, but most often it's done by fathers. (Indeed, seahorse fathers even carry their eggs in a pouch like a marsupial!) The 20% who care for their fry (baby fish) also vary a lot. Actually feeding their fry is rare, although some fish produce infertile eggs for fry to eat, and discus even produce a mucus on their skin that basically serves the same purpose as mammal milk. More often, parental care of fry involves protecting the fry from predators, either by attacking predators (usually a two-parent job) or carrying babies with them (as with mouthbrooding cichlids mothers, who hold babies in their mouth). A few species also have older fry stay and help raise younger siblings, but this is rare.

no. only birds fly south for the winter because of the cold.

elephants

The fruit bat uses sight and smell to locate fruit and navigate. It does not use echolocation (except for one species of Egyptian bat) , as do all other bats.

Some animals have tiny hair

The bat is the only mammal that has 'true' flight. All other 'flying' mammals are gliders.

i dont really know thats what im trying to fi

gure out

Either chimps, great apes, or dolphins.

People argue for all three, but chimps are probably the smartest.

1. Birds have no diaphragm so the abdomen communicates directly with the thorax, this includes the lungs, heart and air sac.

2. Birds have the ability to fly. This is a great advantage when escaping form predators

3. Mammals have the ability to be coordinated on the ground, are able to move easier.

The hollow bones and feathers of birds made them better adapted to their environment than the flying reptiles which became extinct during the Cretaceous Period.

Non-vertebrate chordates are those animals that have a notochord but no true backbone. There are two groups known as the tunicates and lancelets. Tunicates include sea squirts and salps. Lancelets are a group of burrowing filter feeders that live on the ocean floor.

otaku's that see baby's falling from the sky but just before they explode grow wings go back to the stork, get sent to japan and grow up to be like the graphic designers that made junjou romantica

it's a favorite food for deer, slugs and snails.

While in theory possible, due to the large amount of well preserved mammoth remains in the arctic tundra that has lead to a wealth of genetic information, there are still many roadblocks. Mammoth genetics has reached the point where one can in fact download a mammoth genome from researchers, and researchers have inserted mammoth genes into elephant cells in a lab, but one of the primary problems is the elephant (and presumed mammoth) reproductive system. The elephant reproductive system is complicated enough that in vitro elephants are problematic leading to conservation concerns, in vitro mammoths or elephant-mammoth hybrids could be impossible.

Dolphins are born tail first because.......they might die before they got to the surface to breathe!! They are mammals like us, and do not have gills.

There are several mammals which do not have teeth. The echidna is an Australian mammal, a monotreme which only has a sticky tongue. The platypus is another Australian monotreme which has grinding plates, rather than teeth.

Sloths, anteaters, tamanduas, pangolins, baleen whales, and adult monotremes are all toothless mammals.

Fish. They have gills.

Primates are characterized by large brains, a greater reliance on vision rather than smell, 5 digits including opposable thumbs, a tendency towards bipedal locomotion, and rounder heads compared to other mammals. Apes are large primates with no tails that spend more time on the ground than other primates, though they are still adapted to climbing trees. Humans are upright-walking apes with much less body hair and greater intelligence.

Okay, the answer I got for this question was that mammals excrete in two ways. The first was in during the digestive system. It simply means that the waste goes through the body and out the anus. The other way is that they go through chemical waste. This means whenever a mammal breathes for example, you breathe in air but you must breathe out the chemical carbon dioxide from the body.

Up to 15.67 feet long longer than the average elephants trunk

whale, dolphin, otter, sea lion, walrus, seals, iguanas, crocodiles or caymen, sea snakes but of these, only whales, dolphins and porpoises continuously live in the ocean. The others primarily live on land.

snakes, lizards, iguanas
