Vertebrates

Because it has a backbone. see the excellent answer under "IS A SHARK A VERTEBRATE OR INVERTEBRATE" for more info.

1. Notochord

2. A nerve cord

3. Slits in throat area

yeahh, ur welcome.

actually those are characteristics of the phylum chordata. Vertebrates are a subphylum, vertebrata. The distinguishing characteristics of phylum chordata are:

1. A dorsal hollow nerve chord (a bundle of nerves that runs along the back side of the animal as opposed to the ventral or belly side)

2. notochord (what becomes the vertebra in vertebrates but is simply a stiff but movable "rod" in other chordates)

3. pharyngeal slits (slits in the pharynx or throat, only present in many chordates in the embryonic stages)

4. endostyle or thyroid (vertebrates have a thyroid, all other chordates have an endostyle. they both do the same basic thing only a thyroid has some functions an endostyle does not)

5. post anal tail (exactly what it sounds like. obviously many chordates only have this in the embryonic stages as well. humans have one but grow out of it very early in gestation)

Defining characteristics of vertebrates are:

1. Vertebra! (obviously but more specifically the segmented vertebral column)

2. Splanchnocranium (for all intents and purposes, a skull of some sort).

3. Sensory organs to help with balance and head movement (in humans the canals of the inner ear)

4. extrinsic eye muscles for eye movement.

yeahh, ur welcome.

Yes, Hawaiian monk seals do have spines. They are just like other mammals that are vertebrates. In other words, they have backbones.

they are neither because there plants not animals

Felis _______ (genus, specices) Felis _______ (genus, specices)

All insects are invertebrates.

A Beaver is a vertebrate and a mammal.

The octopus is not a member of phylum Chordata, so it is not a chordate.

A vertebrate.

No.

Vertebrates have an internal skeleton and a spine. Therefore, vertebrate can be herbivore (cattle, horses, etc), or carnivore (lion, tiger), or omnivore (human - except those choosing to be a vegetarian or a vegan).

No one is really sure which is the second most vicious animal. It all depends on the animal and it's attitude.

The blowfly is an insect, all insects are invertebrates, the blowfly is an invertebrate.

If we really care about the CO2 in the atmosphere then we need to cut down less trees and re-plant those we have already taken out, then plant another 6 Billion more, yes that is a Billion with a "B". Land Clearing, deforestation and other issues is a huge calamity.

The Rain Forests in Africa, Amazon and other places also at severe risk. Trees take CO2 and turn it to oxygen, and if we plant 6-8 Billion trees we might solve the Climate Change, greenhouse problems. Indeed, we are losing 2-acres a minute as has been noted. Lots of issues out there indeed.

Studying this stuff in the online think tank and all the inter-related issues makes me worry about linear thought guiding our policies, when we need a multiple variable approach and non-linear thinking approach to truly be prudent. In fact we have the technology to use UAVs to fly over and plant more trees.

An internal skeleton that houses the brain and spinal cord. It means they have a back bone.

Lanceletes are invertebrates, because they do not have any spine consisting of a chain of vertebra (vertebral column).

They are however related to vartebrates being a mamber of the fylum (major animal group) chordates (chordata) of which also vertebrates (vertebrata) are a member.

Instead of a vertebral column they have a rod at the same place made of robust connective tissue, a notochord. The spinal cord (nerve string) of this animal is not encased in this primitive spine, but lies posterior to it.

This notochord later developed to a spine consisting of a chain of vertebra in the higher species. The early stages of the embryo of all vertebrates still have a notochord which during the fetal development gives rise to a real spinal column.

Cephalochordates e.g. Amphioxus ,; tunicates , acorn worms etc. are nonvertebrate chordates , they are collctively called protochordates .

The mudskipper is a fish. It is a member of the Domain Eukarya and the Phylum Chordata. Although it is amphibious, it has all the characteristics of a fish, having scales and breathing through gills.

bat rays are fish. all fish are vertebrates.

Frogs were actually the first animals to fly, contrary to popular belief. When they first existed, frogs had large beautiful wings. Some say they were from Jupiter. The frogs had a pact with the birds, who actually didn't have wings at that time. The birds, however, envied the frogs' wings. They figured out that the frogs' power of having wings came from their possession of the spring of Red Bull (those that think that frogs came from Jupiter believe Red Bull also originates from Jupiter). The birds wanted the power of wings, so one day they made a bet with the Frog King.

The birds' favorite athlete was Brett Favre (yes, he is that old). They placed a bet saying that his team would win the championship football game, the SuperPlate. The Frog King's pride in his own favorite player led him to make the bet. If the frogs won they would be able to sing like the birds and if the birds won they would get the Red Bull spring. I won't go into detail, but obviously, the frogs lost. (On a side note, this was actually Favre's first SuperPlate win.)

Now frogs spend their days thinking of the past and trying to gain their powers back naturally. They live by the saying "You are what you eat," which is why they eat every fly they can find. They often jump, testing their powers, only to find themselves back on the ground. This is the story of how frogs, the first animals to fly, became what they are today.

Ducks breathe the same way as us humans

A speckled flying fox is most defiantly a vertebrate. All mammals are vertebrates being a part of the phylum chordata.

The first vertebrates to come onto land were fish-like animals that developed lungs and could thus stay on land for extended periods. These evolved into terrestrial amphibians (although many amphibians require water in which to lay eggs, and some are aquatic).
