What the sources say
Beadlet AnemoneActinia equina
Every figure, record and mechanism on the Beadlet Anemone profile was written from a source, and this is the working table behind it: 35 claims checked word for word against these sources. The left column is what the page says. The right column is the source's own words, copied, not paraphrased; a ... marks a cut and[brackets] an insertion. Open any source and check it yourself.

- The page saysA red blob on the rocks
- The source says
looking like a little red blob
- The page saysAlmost anything it can catch, most often bivalves, insects and isopods
- The source says
is known for eating almost anything it can catch. The most abundant food sources for this anemone are: bivalve mollusks, insects, and isopods.
Note: 'most often' paraphrases 'most abundant food sources'; the quote names bivalve mollusks - The page saysA beadlet anemone sits on a rock
- The source says
Attaching to rocks, stones or other hard substrates
- The page saysrust-red is the most common
- The source says
The most common hue is rust-red.
- The page saysAnimal Diversity Web gives a dry weight of 0.01 to 0.84 g.
- The source says
from 0.01 to 0.84 g dry weight
Note: average 0.42 g from the 'Average mass 0.42 g' field of the same page - The page saysan anemone in the water is mostly water it has absorbed
- The source says
when anemones are in the water their body mass is primarily the amount of water absorbed in the tissue and in the gastrovascular cavity
- The page saysOut of the water it is always retracted and looks like a little red blob.
- The source says
However, it is always retracted when it is out of the water, looking like a little red blob.
- The page saysit eats almost anything it can catch, and its toxins paralyze the prey and inhibit its ability to escape
- The source says
is known for eating almost anything it can catch ... These toxins paralyze the organism, inhibiting its ability to escape.
- The page saysIt has three main defenses: inflating its body column, detaching from the rock in a bid to escape predation, and releasing stinging cells with toxins.
- The source says
have three main defensive behaviors which include: inflation of the body column to reduce damaged areas, detachment off the substrate so they might escape predation, or release of the nematocytes containing toxins.
Note: Source says 'so they might escape predation'; 'in a bid to' keeps that hedge. - The page saysThe grey sea slug still eats it, and somehow does not digest the most toxic stinging cells.
- The source says
Despite its stinging cells, the grey sea slug, Aeolidia papillosa preys on A. equina. The sea slug somehow does not digest the most toxic stinging cells.
- The page saysgenetic studies suggest the differently colored beadlets may be separate species
- The source says
Recent genetic studies suggest the different colored Actinia equina may actually be distinct species.
Note: ADW's 'recent' dropped: the account is undated and old, so the page does not call the studies recent - The page saysAnimal Diversity Web says that contact with a human can cause great discomfort and pain, and that its nematocysts hold powerful toxins.
- The source says
It has powerful toxins (e.g. equistatin and equinatoxin) in its nematocysts that it uses for feeding and defense. If a human comes in contact with it, it can cause great discomfort and pain.
- The page saysBivalve mollusks, insects and isopods are its most abundant foods, while snails, slugs, bryozoans and chitons supply the largest food mass.
- The source says
The most abundant food sources for this anemone are: bivalve mollusks, insects, and isopods. However larger organisms such as gastropods (snails and slugs), bryozoans, and chitons are what provide the largest food mass.
- The page saysThe average is 0.42 g.
- The source says
Average mass 0.42 g
Note: dry weight, same page - The page saysOut of the water a beadlet anemone pulls in and sits as a little red blob, and when its tentacles touch a neighbor's it stings.
- The source says
looking like a little red blob
Note: vibe.reason; the rest of the sentence restates body claims: is aggressive toward the anemones next to it, and a fight starts when the tentac; Out of the water it is always retracted and looks like a little red blob.

- The page sayspicks fights with its neighbors using stinging blue spots

Actinia equina displays aggressive behaviour towards neighbouring individuals. This aggressive behaviour is stimulated when the tentacles of adjacent anemones come into contact. The aggressor stings the victim with nematocysts, in the acrorhagi

- The page saysThe dose that killed half of the mice tested was 23, 35 and 83 micrograms per kilogram for equinatoxins I, II and III, injected into a vein.
- The source says
the acute i.v. LD50 in mice of equinatoxins I, II and III were 23, 35 and 83 micrograms/kg, respectively

Lethal and hemolytic toxins were purified by acetone precipitation, Sephadex G-50, CM-cellulose and CM-Sephadex column chromatography from the tentacles and bodies of the sea anemone Actinia equina.

- The page saysEquinatoxin II opens pores in cell membranes. In red blood cells that causes hemolysis, the breaking open of the cells
- The source says
Red blood cell (RBC) hemolysis by EqT-II is the result of a colloid-osmotic shock caused by the opening of toxin-induced pores.
- The page saysthe pores were estimated to have a functional radius of about 1.1 nm
- The source says
the functional radius of the lesion was estimated to be approximately 1.1 nm
How the table was made: a writer drafted the profile from these sources and logged each claim with its quote, a reviewer with nothing but this table checked every sentence said no more than its quote, and a script confirmed each quote appears word for word in the source. The method is in the site'sAbout page.
