A mammal consists of a spine because it is a vertebrate and has to be warm-blooded. A coconut does not have a spine or is warm blood so there for it is not a mammal.
What makes a mammal a mammal?
What five characteristics do mammals have in common? Mammals have hair or fur; are warm-blooded; most are born alive; the young are fed milk produced by the mother’s mammary glands; and they have a more complex brain than other animals.
What is the hair on coconuts called?
coir, seed-hair fibre obtained from the outer shell, or husk, of the coconut.
Do coconuts have milk in them?
Unlike coconut water, the milk does not occur naturally. Instead, solid coconut flesh is mixed with water to make coconut milk, which is about 50% water. By contrast, coconut water is about 94% water. It contains much less fat and far fewer nutrients than coconut milk.
Is coconuts a living thing?
A coconut is a big seed. Planted,you will get a living thing-a coconut palm. Unplanted they will eventually decay though that hard shell can protect it for quite a stretch. Coconuts float well and have drifted to,and planted themselves,on many island.
Why is a shark not a mammal?
Despite names like ‘whale shark’, all sharks are fish and differ in many ways from mammals. For example, mammals breathe air through lungs, feed their young with milk and are warm-blooded. Sharks pass water over gills to breathe, don’t have mammary glands and (with the exception of mackerel sharks) are cold-blooded.
What was the first mammal on earth?
morganucodontids
The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago. They were one of several different mammal lineages that emerged around that time. All living mammals today, including us, descend from the one line that survived.
Why do coconuts have three holes?
The three “holes” are the result of the 3 carpels in coconut flowers, and three carpels is typical of the family Arecaceae (Palms). The “holes” are actually germination pores, where one is usually functional and the other two are plugged. The new coconut shoot will emerge from the functional, open, germination pore.
Do coconuts breathe?
They do not breathe but the loose texture of their cortical cells, which swell up and flare out like the powdery tissue of lenticels in tree trunks, allows the ready diffusion of gases into and out of the rootlets.
Why do coconuts have milk in them?
It’s actually what we call the endosperm of the coconut plant. That’s the stuff that gives the nutrition for the developing seed, a bit like the flesh of a banana. As the fruit ripens, the coconut water gets converted into the solid fruit that you find in there.
Can you drink water straight from a coconut?
Coconut water is a sweet, translucent fluid that you may drink straight from young green coconuts. It comes naturally within the fruit and is referred to as the liquid endosperm ( 2 ).
Why can’t I drink brown coconut water?
But since a mature, brown coconut contains little water, it may have fermented in the heat and will have a distinctly sour or alcoholic flavor. This coconut water is unsafe to drink, as the likelihood of containing bacteria is very high. If there are any signs of bubbles in the coconut water, discard it immediately.
Why do coconuts have hair on them?
At first blush, the hairy exterior of coconuts would appear similar to the furry surface of mammals, but looks can be deceiving. Instead, the fibers of coconuts are the outer layers of the husk, and the husk serves as a hard carapace protecting the nut inside.
What is a coconut classified as?
Coconuts are classified as a fibrous one-seeded drupe. A drupe is a fruit with a hard stony covering enclosing the seed (like a peach or olive) and comes from the word drupa meaning overripe olive.
What is the white ball inside a coconut?
Coconut Embryos are basically a soft, spongy formation that are found inside mature coconuts. When the coconut is ready to sprout leaves, this formation takes place on the inside. The ’embryo’ is actually a cotyledon and it is generally eaten raw.
Why is a coconut not a nut?
Due to the hard shell and its name it’s tempting to think of the coconut as a nut. However, it’s technically a special type of fruit called a drupe which contains its seed within a hard stone or shell which in turn is contained within a fleshy (or in the coconut’s case, fibrous, outer layer).
Is a dolphin a mammal?
Dolphins are mammals, not fish
Also, dolphins are different than “dolphinfish,” which are also known as mahi-mahi. Like every mammal, dolphins are warm blooded. 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.
Are sharks afraid of dolphins?
Just like we check under our beds for monsters, sharks check for dolphins before nodding off. That’s right, the toughest kids on the undersea block swim in fear of dolphins. Here, we’ve compiled a splash of facts to tell you why. Flexibility Gives Dolphins the Upper Fin.
Are octopus mammals?
It’s a great guess, but an octopus is not a mammal. An octopus is an invertebrate animal, which means it has no spine. More specifically, an octopus is a cephalopod, like squid and cuttlefish. They’re some of the smartest invertebrates.
What existed before dinosaurs?
For approximately 120 million years—from the Carboniferous to the middle Triassic periods—terrestrial life was dominated by the pelycosaurs, archosaurs, and therapsids (the so-called “mammal-like reptiles”) that preceded the dinosaurs.
Did humans and dinosaurs coexist?
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
