Invertebrates

Seahorses can make wonderful aquarium pets. As long as one understands that there are few other tank occupants that can be introduced into a seahorse tank, the tank needs to be a slow moving tank and decor needs to be added for anchoring. Seahorses are not strong swimmers so the tank shouldn't be too large, fast moving or lacking in anchor spots.

These wonderful animals are not a good beginner saltwater fish. Seahorses also will not do well in an aquarium with most other fish or with stinging invertebrates (anemones, corals). They require careful feeding and very good water quality. Read up as much as you can on keeping seahorses to be successful with them.

Buy captive-bred seahorses (rather than wild caught) both to limit disease (common in wild-caught) and to ensure that they will eat frozen foods.

All save for sharks, rays and chimaeras. All other fish are bony fish (Osteichtyes).

They don't have a backbone and have all the characteristics of a chordate.

The brain is used for movement because they lack a spinal cord. Brain sends signals for movement through tissues

They are in the mollusks group.

it eats on palants

Yes.. Invertebrate animals have one type of bone and that is the skull.

a hyrax is a verterbrate

These animals are not like Arthropods and they are:

Sponges

Molluscs

Flatworms

Round Worms

Echinoderms

Cnidarians

Annelids

They are supported by their hydroskeleton.

by using vibrations in the ground

Yes, the male Black Widow has venom. But they are very shy, much smaller than the female, and much less aggressive. Their diminutive physique means they have small fangs, small amounts of venom, and they can't deliver the kind of deep bite (and high venom volume) that the female can. Unless you saw a male Black Widow in the web of a female courting it, you'd likely never notice or otherwise encounter one. A link can be found below so you can at least see a picture of a "couple" of these arachnids. You're looking "up" at them from their ventral side, and the red hourglass of the female is very apparent.

Jaguar are vertebrates because they have a backbone (spine).

Echinoderms are marine animals that are invertebrates, while Chordates are animals with backbones. Hope this helps!

Actually it is called a balance - scales are in music and on fish.

ha ha ha

Yes a black adder is very poisonous and in fact deadly. The adder is the snake Cleopatra put to her throat to bite and kill her. People should not interact with this animal.

they a hide a good enviroment

seriously? wow....... did you pass 4th grade? invertebrate

a cicada is an in vertebrate

Yes they are. To be a vertebrate you need a spinal column(a back bone) which cheetahs posses.
yes.

invertebrates are animals WITHOUT spines
