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.
Most species of sea anemones are harmless to humans, but at least some species of the genus Stichodactyla are highly venomous and their sting may cause anaphylactic shock and organ failure (notably acute liver failure). [2] [3] In contrast, the venom of Radianthus spp. has shown potential in the treatment of lung cancer. [4]
Pachycerianthus fimbriatus is a cerianthid anemone that burrows in substrate and lives in a semi-rigid tube made of felted nematocysts. The anemone is often seen in bright orange to red. Like most anemones, the tube-dwelling anemone contains stinging cells or nematocytes along its tentacles, however, the cells are not toxic to humans.
The blue-ringed octopodes (Hapalochlaena spp.) produce tetrodotoxin, which is extremely toxic to even the healthiest adult humans, though the number of actual fatalities they have caused is far lower than the number caused by spiders and snakes, with which human contact is more common. [8]
Sea anemone neurotoxin is the name given to neurotoxins produced by sea anemones with related structure and function. Sea anemone neurotoxins can be divided in two functional groups that either specifically target the sodium channel or the potassium channel.
Actinodendron arboreum, commonly known as tree anemone or hell's fire anemone, [2] is a species of sea anemone in the family Actinodendronidae. [3] It is native to the Indo-Pacific where it grows at depths of down to 28 metres (92 ft). [ 4 ]

The following is a list of poisonous animals, which are animals that passively deliver toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested.
