Invertebrates

Invertebrates can be herbivores, carnivores or omnivores. Caterpillars are herbivores, for example, while spiders are carnivores.

snakes, lizards, iguanas

All invertebrates have no backbone and most usually have a had covering much like a wax water proof covering, also all invertebrates can be traced back to have ancestors that were once only aquatic.

they hide behind sea plants and sneak up on the prey. they attack when they see a prey. usally they cacth them but not always

no, mammals are grouped together because they all posses hair, lungs and mammary glands (hence the name) to produce milk, and a few other features. the urchin does not posses any of these quality's and therefore is not a mammal

I don't think they do...I could be wrong but I think all mollusks have a foot, visceral mass, and a mantle.

Terry Nichols was convicted for being an accomplice in the 1995 bombing of the Federal Building in Oklahoma City. The bombing killed 168 people including many children.

Diatoms are plantlike protists of the phylum Bacillariophyta.

Giant squids, like other squids, have beaks, not teeth.

Lady bugs are classified in kingdom animalia(all animals): they are part of phylum arthopoda and their class is insecta.They belong to the order of coleoptera.So yes they are invertebrates...

1. they are animals that doesn't move only the move in there recital for an inchs only and we classify it as predator because its a flower

ALL fish, amphibians, reptiles, birds and mammals are VERTEBRATES. A gerbil is a mammal.

The major difference between echinoderms and other invertebrates is that there are few examples echinoderms that do not live in ocean water and none live on land. There are examples of other invertebrates that live in both fresh and salt water and on land. Echinoderms also display radial symmetry as do the jellyfish and sea anemones. If you want to tag the one thing that echinoderms have that no other living invertebrate has, you would probably have to point to their water vascular system (see link).

If you have the McGraw Hill science textbook for 6th grade then you are all set. Look on pages A40-A48.

Fungi are neither plants or animals, they are fungi. Once again, fungi are neither invertebrates or vertebrates, they are fungi.

It's actually MOLLUSKS.

• Porifera (Sponges)
• Cnidaria (Coelenterates)
• Flatworms (Platyhelmenthes)
• Roundworms (Aschelmenthes - Nematode)
• Segmented worms (Annelids)
• Mollusks (Soft-Bodied/ hard shelled Animals)
• Echinoderms (Spiny-Skinned Animals)
• Arthropods

Vertebrates came first... all of those other creatures are vertebrates..

prior to the evolution of the spine (vertebrae) there were no fish, reptiles, mammals birds... nothing like them..

radial symmentry

starfish

They have Bilateral symmetry as a larvae but as they mature they get secondary symmetry. Starfish with five arms have pentaradial symmetry and sea cucumbers and ect. have radial symmetry

There are two main ways they protect themselves. First, anemone tentacles are venomous, and can numb small animals. This is usually more useful for stinging prey (ie tiny zooplankton) rather than predators, though. There is a useful byproduct to this venom in some species, which is symbiosis with fish that are immune to the venom and live in the tentacles. These fish can help the anemone by fending off possible predators, protecting both their interests and the anemone itself.

There's also a more rarely used behavior, which is "swimming." If an anemone is touched by a predator and the anemone recognizes a specific chemical, it will detach from its substrate and repeatedly bend in half to try and catch a current to sweep it away from danger. Unfortunately this requires a huge amount of energy, of which anemones don't have much. If they fail to catch a current or are dropped near another predator, they're pretty much out of luck.

Worms do not have an exoskeleton like insecta or crustacea, but rather a membrane that covers it's entire body. I am not sure whether or not it is hydrostatic, though I highly doubt it.
