Vertebrates
Vertebrates belong to the subphylum Vertebrata – the largest subphylum of chordates containing several groups of large land animals including mammals, birds, reptiles, amphibians and fishes. Vertebrates have spinal columns and backbones. There are now around 58,000 species of vertebrates.

What was the last vertebrate on earth?
Vertebrates are basically animals with backbones. The "last vertebrate on Earth" doesn't make sense unless you are reading a story about the end of the world or possibly a creation myth. There are currently a vast number of vertebrate species and identifying the last one to appear would be virtually impossible.
From a scientific perspective, it makes much more sense to ask when did the first vertebrates appear on Earth, or which vertebrates have appeared most recently. Within the fossil record, there would be an oldest fossil of a vertebrate that would be a good candidate for he first vertebrate. Alternatively, you might choose a larger group of organisms like mammals and ask which was the last class of organisms to appear in the fossil record. In this case, the class of vertebrate whose oldest known fossil is the youngest or most recent could be called the last vertebrates on Earth.
On the other hand, if you are somehow taking a class or thinking in a way that combines science and religion in a nonscientific way, it might be possible to answer the question based on the Christian creation story by saying "humans" or even "Eve." In this case, the question would be better phrased as "When God created the world, which was His last creation that would today be called a vertebrate?" In this case, the question is almost a riddle.
Is a wing of a bird homologous to the wing of a cat?
In biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
Is a finch a vertebrate or invertebrate?
The goldfinch is a vertebrate. Like all birds, it has a backbone. Birds, mammals, fish, reptiles and amphibians are all vertebrates.
Fish are vertebrates as they have an internal bony skeleton and a spine.
Is a rattlesnake a vertebrate or an invertebrate?
No. All reptiles, including snakes, are vertebrates. They all have backbones. They have all the organs we do (except some snakes only have one lung).
EDIT: All snakes have one functional lung and most have a vestigial left lung.
What vertebrate group has three major groups egg-laying pouched and placental?
Mammals has these 3 groups .
Is an octopus a cold blooded vertebrate?
Octopus, as with most current invertebrates, are exothermic or cold-blooded.
How long for spider eggs to hatch?
It should take a few days or weeks, months at the max.
Improvement: I've been keeping an orbweaver spider for the last week or two and she made her nest about 5 days ago. I'll try and get back to this board when they hatch.
I copied this answer from Yahoo
Most crab spiders will have two successful hatches of eggs every year. Once the eggs are attached, the female will stay within the vicinity, like you are already observing. The time it takes for the eggs to hatch is based on several parameters, the most important being temperature. The best option in captivity is not to alter the temperature too drastically. Maybe place a small lamp near the eggs and keep them at room temperature, but turn off the light at night to better mimic natural conditions. It could be anywhere from 2 weeks to a month, but probably closer to 2 weeks.
Once the eggs hatch, the young spiderlings are still soft and fragile, and usually will not start eating each other for about 2 days or so....this is not always the case, but as a general rule, they typically need at least a day for their tiny exoskeletons to harden before they start searching for a meal. Your best option is to leave them for a day, and then release them, once outside they will disperse on their own.
You can hold onto your female because she may not be done laying eggs, many spiders are capable of storing sperm for long periods, and she may be able to producer another clutch of eggs, especially since you mentioned she is eating well.
Is an alligator a vertebrate or invertebrate?
Alligators are vertebrates because they have a backbone.
Is a walking stick invertebrate or vertebrate?
Yes a walking stick is an animal.(WaHL-kIng Stick)
Why is the animal walking stick called a walking stick?
Because in Britain they say that these creatures look like a tree branch or a walking stick.
These creatures are about 8-10 inches long!!
What are the adaptations that enable vertebrates to survive on land?
The ability for the aquatic animals' lungs to breathe the air on land. And the feet and mobility changes.
Which group of animals are invertebrates and vertebrates?
There is no animal that is both vertebrate and invertebrate, as vertebrate means that said organism has a spine. Some examples of vertebrate animals include humans, dogs, snakes, and birds. Invertebrates include organisms like jellyfish, crustaceans, insects, worms, and corals. There are different divisions of both invertebrates and vertebrates. For invertebrates, the sections are:
- Arthropods (arachnids, crustaceans, insects, and others);
- Molluscs (octopi, squids, and others);
- Echinoderms (starfish, sea urchins, sea cucumbers)
- Porifera (sponges)
- Cnidarians (jellyfish)
- Platyhelminthes flatworms)
- Nematoda (roundworms)
- Annelida - segmented worms
- Bryozoa - sea mats or moss animals (occasionally resemble coral)
- Fish
- Reptiles
- Mammals
- Birds
- Amphibians
there are six groups ofinvertebrates. There are the insects, arachnids and crustaceans. There are also mollusks, worms, and sponges.
It is a vertabrate. inverabrates have no back bones, while poodles very much so have a back.
in order to be a vertebrate you need to have a back bone. and because clowfish do have back bones they are there for vertebrates.
What makes a fish a vertebrate?
The fact that they have an internal skeleton and a backbone. because it has a back bone
okay so you want to know if shrimp are vertebrates? Well shrimp have an outer skeleton instead of an an internal one like us that is called exoskeleton how ever they do not have back bones which allows them to be more flexible animals such as the shrimp are called invertebrates (without backbone)
It is a fish, not a mammal.
- Fish lives is a aquatic vertebrate, lives in a water, breath with gills, and most of them are cold-blooded, allowing their body temperatures to vary as ambient temperatures change.
- Mammals are members of air-breathing vertebrate animals, have a placenta which feeds the offspring during gestation.
What animals with a vertebrate start with the letter A?
Basically any mammal, reptile, bird, and I guess some amphibians and fish that start with the letter A. They're things like the aardvark, armadillo alligator, ape, Adelie penguin, Alligator gar, American robin, angelfish, anaconda etc.
Is a sea lamprey an invertebrate?
Lampreys are consumers. Some species are strictly larval feeders and some are parasitic.
