Invertebrates

all animals have special charicteristics and adaptations that help then survive including invertebrates.

birds attract there mate by singing hope it helped

Amphibians undergo external fertilization and need to do this in the water. Both the male and female amphibians release their gametes close to each other after which fertilization will take place.

A Gila Monster can swim but for only short distances and not for very long

They produce oxygen during photosynthesis.

They hide under rocks and corals

Alligators are vertebrates because they have a backbone.

Yes, like all birds.

yes, worms are made up of cells and all cells have a nucleus.

The crab is in the crustaceans.
Crabs are grouped in various ways with other arthropods, being in a major taxonomic group called a phylum (Arthropoda) all of whom are characterized by hard exoskeletons, joint appendages, and segmented bodies. Since arthropods are such a major group, branching classifications below it also can be said to be crab "groups" or taxa. For example, they are in a subphylum Crustacea, class Malacostraca, order Decapoda, and suborder and infraorder Pleocyemata and Brachyura respectively.

An okapi is a mammal in the family giraffidae, along with giraffes. it lives in the rainforests of the democratic republic of the congo. it resembles a short a giraffe,with dark fur on its torso and stripes on its flanks. It is currently an endangered species

Anemones are a genus of up to 120 species of the flowers. They come in different shades of the following colours: green, blue, brown, red and teal. they are often sold as a mixture of colours.

Clams donÕt basically grow; they actually shed their shells through a process called molting. After a few days, a new shell will grow on the shell edge of a clam.

Female seahorse lay eggs, which the male seahorse carry in a pouch on his stomach until they hatch.

Spiders and praying mantids are examples of carnivorous (or rather, insectivorous) invertebrates.

just a big ball with legs something like that

The spiky spines of purple sea urchins range in colours depending on the exact species and the maturity of the urchin.

They can range from light blue, dark blue, royal blue, indigo, light purple, violet and dark purple.

They do not give birth. They release sperm and eggs into the water, some species retain the eggs in their shell for incubation.

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.

The structure in an echinoderm that is a bulb like sac and pushes what is called the ampulla. It is connected to the radial canal of the water-vascular system. Each ampulla controls tube feet. The tube feet can extend when water pressure is increased by the ampulla being squeezed.

Cnidereans have pressure-sensitive poison glands called nematocysts that are usually on their tentacles. When their [prey] touches these nematocysts, small "fangs" inject poison into the [prey]. The poison in the nematocysts can paralyze or even kill small animals. Once the prey is subdued, the tentacles pull the prey towards the mouth.

There are a couple of classes in the phylum Cnidaria : Schyphozoa, Cubuzoa, Anthozoa, Hydrazoa. Scyphozoa consists of the true jellyfish. Cubozoa are jellyfish with a cube/box shaped medusae stage. The main genus that make up the class Cubuzoa is the Box Jellyfish : A jellyfish with the deadliest venom in the animal kingdom. Hydrazoa's are smell marine animals including the Hydra, and the Porteguse Man of War. Anthozoa includes Sea Anomenes and Corals. These organisms are generally in the polyp stage throughout their life.

Sea cucumbers are part of Phylum Echinodermata along with starfish, sea urchins, sand dollars, crinoids

and brittle stars..
