In humans, stems cells allow limited regeneration of certain cells in our body (which is why they’re central to the exploration of anti-aging therapies), however, other animals display much ...
A typical sea anemone is a sessile polyp attached at the base to the surface beneath it by an adhesive foot, called a basal or pedal disc, with a column-shaped body topped by an oral disc. Most are from 1 to 5 cm (0.4 to 2.0 in) in diameter and 1.5 to 10 cm (0.6 to 3.9 in) in length, but they are inflatable and vary greatly in dimensions.
Aiptasia is a widely distributed genus of temperate and tropical sea anemones of benthic lifestyle typically found living on mangrove roots and hard substrates. These anemones, as well as many other cnidarian species, often contain symbiotic dinoflagellate unicellular algae of the genus Symbiodinium living inside nutritive cells.

There are thousands of different species of sea anemones in the ocean with some living as far deep as 32,000 feet. ... The anemone sits still on the ocean floor atop its stem-like body. At the ...
A number of sea anemone species are commensal with other organisms. Certain crabs and hermit crabs seek out sea anemones and place them on their shells for protection, and fish, shrimps and crabs live among the anemone's tentacles, gaining protection by being in close proximity to the stinging cells.
These sea anemones exclusively reside within the shallow waters of the tropical Indo-Pacific area and are in the main family of sea anemones that hosts several varieties of clownfishes. [1] Most sea anemone species are harmless to humans, but at least some Stichodactyla are highly venomous and their sting may cause anaphylactic shock and organ ...
When a predator approaches the anemone, their reaction is to withdraw their tentacles and oral disc. These are the preferred attack sites for predators, because the concentration of anthopleurin is the lowest in these sites. The body region of the sea-anemone that is exposed to the predator contains the highest concentration of anthopleurin.
