No.
I believe you are refering to the "canine teeth" Definition of Canine Tooth: a conical pointed tooth ; especially :one situated between the lateral incisor and the first premolar
They do not have a lateral line but at least some have a lateral line analogue, the epidermal head lines, that are compromised of mechanosensory hair cells and detect water displacement (Budelmann & Bleckmann 1988, J Comp Physiol A)
No, not only mammals have nipples. Nipples are also found in some other animals, such as birds and some reptiles.
A baculum is a bone found in the penis of some mammals.
Some examples of blue mammals found in the wild include blue whales, blue monkeys, and blue poison dart frogs.
Many amphibians are born with lateral lines. As they grow older, some amphibians such as salamanders lose their lateral line because it's no longer a necessity due to the fact they also walk on land.
Fossils of dinosaurs and mammals have been found in the same strata. Mammal bones have been found in the stomachs of some predatory dinosaurs.
it depends, it can range from almost anything. but most mammals are found on land, some are in the sea, e.g. a seal. you'll have to be more specific for the right answer
There are many such features, including: 1. Mammals nourish their young with milk. 2. Mammals are warm-blooded. 3. Mammals have fur. 4. Mammals have a four-chambered heart. 5. Mammals are amniotes. 6. Mammals breathe oxygen. 7. Mammals have three middle ear bones and a neocortex. 8. Mammals have internal reproduction. Some of these characteristics are unique to mammals; others are found in some other vertebrates but not in all other vertebrates.
Problems can often be solved by some lateral thinking.
Yes some mammals can be wild.
Different mammals eat different food. Mammals occupy varying places on a food chain. Some mammals are vegetarians, they are primary consumers. Some mammals are carnivores, they are higher level consumers. Some mammals are omnivores.
