The horseshoe crab is an example of an animal that has both vertebrate and invertebrate features. It has a hard exoskeleton like an invertebrate, but also possesses a primitive form of a segmented backbone similar to vertebrates.
A wasp is a predatory animal and not a parasite.
A mollusk (mollusc) is an invertebrate. Some mollusks (e.g. snails, shellfish) have hard exoskeletons.
spiky skin, hard scales shark
Yes, they do. They have hard scales for protection.
Approximately 5% of animal species have a backbone, classifying them as vertebrates. The vast majority, around 95%, are invertebrates, which do not possess a backbone or bones. While some invertebrates, like certain mollusks, have hard structures, they do not have a skeletal system like vertebrates. In summary, only a small fraction of animal species have bones.
backbone
The Answer would be invertebrate : ) ... !
No, starfish do not have a backbone. They belong to a group of animals known as echinoderms, which have a hard, calcareous exoskeleton made up of plates called ossicles. This exoskeleton provides structure and support, but it is not a true backbone like vertebrates have.
Amphibians do not have hard scales. Their skin is smooth. It is covered in a thin layer of mucus to keep it moist.
No they do not. They have a hard shell (exoskeleton) instead.
Rough and scaley.
