Sea anemone
* Many sea anemones reproduce by cloning, literally splitting in two.
* Most sea anemones are predacious, immobilizing their prey with the aid of their nematocysts
  - attach themselves to hard surfaces, such as rocks and other animals
  - eat crabs
* Most sea anemones have microscopic algas
  - mouths
  - organs
  - sense organs
* Some sea anemones can even burrow.
* Some sea anemones have brains
  - digestive enzymes
  - disks
  - necessary digestive enzymes
  - kill prey
  - live in symbiosis with other animals
* Some sea anemones provide food
  - homes
* Some sea anemones reproduce sexually while others reproduce asexually
  - through another form of asexual reproduction called pedical laceration.
  * Some sea anemones live in symbiosis with other animals. Clownfish, Bucchich's goby, and Sipder crabs find shelter among the tentacles of the anemone. Hermit crabs often have sea anemones on the shell they inhabit
* allow for both clownfish and juvenile damselfish to live within their tentacles.
* anchor themselves to substrates and wait to catch prey in their outstretched tentacles.
* are a group of water-dwelling, predatory animals of the order Actiniaria
  - anthozoans
  - carnivorous
  - close relatives of corals
  - coelenterates, and their tentacles have numerous stinging cells called nematocysts
  - part animal, part plant at the genetic level
  - polyp-shaped, sedentary sea creatures that tend to resemble flowers
  - related to corals and more distantly to jellyfishes
  - sessile organisms
  - solitary animals but can form dense concentrations
* can be dangerous depending on their sizes and their level of toxic
  - change their shape because of their skeletal system
  - close up, pulling all their tentacles insidse their bodies
  - reproduce sexually or asexually
  - vary in frequency from year to year
* come in different sizes and many different colors.
  - fish whole and where they caught it
  - prey to supplement the food that marine algae create in their tissues
* feed on various invertebrates and fish.
* filter the bacteria from the water.
* fold themselves up when the tide is low to preserve the moisture inside their bodies.
* grow in the pools on the cavern floor.
* harbor resident pink anemonefish.
* have algas
  - poisonous sting that only clownfish and certain damselfish can tolerate
* lives in all the oceans and at different depths.
* look like plants, but they are really meat-eating animals.
* polypeptides mimic anthopleurins in producing a digitalis-like cardiac action.
* position themselves in a way as to increase light exposure to their symbionts.
* provide an aquarium with bright pops of color as well as with shelter for clownfish
  - shelter to the fish and other creatures in the reefs
* reproduce asexually by slowly pulling themselves in half.
* show significant potential as sentinel organisms with respect to biological endpoints.
* spend most of their lives in one place.
* stay in one place, using tentacles to catch small animals that drift through the water.
* use their stinging tentacles for defence
  - tentacles to catch food
  - two types of asexual reproduction

Sea pen
* are colonial octocorals which exhibits polyp dimorphism
  - fenced off portions of open either seawater or a lagoon
  - soft-sediment dwelling soft corals that are often found in great beds
  - suspension-feeding animals
* inhabit soft-bottomed aquatic environments.

Common animal
* are brown snake, field sparrow, red-winged blackbird, and American goldfinch
  - crabs, chitons, brittle stars, and sea anemones
  - giraffes, lions, elephants, jackals, hyenas, and monkeys
  - lizards, rats and donkeys
  - prairie dogs, gophers, and ground squirrels
* belong to the deer family such as moose, elk, and regular deer.
