Female black-faced blenny
Territorial male black-faced blenny

The black-faced blenny (Tripterygion delaisi) is a species of fish in the family Tripterygiidae, the threefin blennies. It is found in the Mediterranean Sea and adjacent Atlantic Ocean coasts, at depths from 3 to 40 metres (10 to 130 ft), and prefers shaded areas such as rock faces and crevices. During the breeding season, territorial males develop a characteristic yellow body with a black head, while females and other males are coloured grey-brown for camouflage. The black-faced blenny produces a red fluorescent signal using specialised cells in the iris, which it can regulate in brightness. Males defend nesting territories beneath overhangs, aggressively repelling intruders and defending the eggs from predators until they hatch. These black-faced blennies, one female and the other a territorial male, were photographed in Arrábida Natural Park, off the Portuguese coast.

Articles are to be written from a neutral point of view. Wikipedia is not concerned with facts or opinions, it just summarizes reliable sources. This usually means that secular academia is given prominence over any individual sect's doctrines, though those doctrines may be discussed in an appropriate section that clearly labels those beliefs for what they are.

Objective

  • Wikipedia's goal is to build and maintain an encyclopedia covering all branches of human knowledge.[1]
  • Medical topics: Jimmy Wales response

No, you have to be kidding me. Every single person who signed this petition needs to go back to check their premises and think harder about what it means to be honest, factual, truthful.

Wikipedia’s policies around this kind of thing are exactly spot-on and correct. If you can get your work published in respectable scientific journals – that is to say, if you can produce evidence through replicable scientific experiments, then Wikipedia will cover it appropriately. What we won’t do is pretend that the work of lunatic charlatans is the equivalent of “true scientific discourse. It isn’t.

Nicely done. Wales is essentially saying, we have standards. Deal with it.[2][3]

  • Wikipedia co-founder calls alt-medicine practitioners “lunatic charlatans”[4]
  • Knowledge is often defined as justified true belief.
    Knowledge, Awareness of facts or being competent.
