The Yucatec Maya etymology is attractive and often cited by Internet sources, but the little-known attestation of shark in a mid-15th-c. English document rules out any such hypothesis. The word is embedded in a Latin text as le Shark. The ostensibly French definite article simply tags the quoted word as non-Latin (according to the Anglo-Latin conventions of the time) and does not imply a French etymology.

In Arabic the word is Krsh (the mirroring of SHARK) It's in the Arabic dictionary Lisan Al-Arab, written during the 13th century, long before the English usage of the word. --Mando Salama (talk) 10:52, 2 February 2015 (UTC)
Also attractive, but proves very little. Arabic had no major influence on Middle English at the time and besides, there is no explanation as to why they would straight up invert the word if they did borrow it. Bataaf van Oranje (Prinsgezinde) (talk) 12:59, 10 May 2016 (UTC)
Could someone explain the following? Seems to contradict.
-Buoyancy: Most sharks need to constantly swim in order to breathe and cannot sleep very long without sinking (if at all).
-Respiration: While at rest, most sharks pump water over their gills to ensure a constant supply of oxygenated water. A small number of species have lost the ability to pump water through their gills and must swim without rest.188.8.131.52 (talk) 16:33, 11 June 2016 (UTC)
It is the buoyancy section section that is misleading. Fixed

For shark lifespans strange the Greenland shark's not mentioned as possibly longest lifespan it is believed to live 200years, even the wikipedia entry for that shark says that. Suggest that gets edited. — Preceding unsigned comment added by 184.108.40.206 (talk) 11:53, 12 July 2016 (UTC)
The spiny dogfish has the longest lifespan at more than 100 years
The spiny dogfish has one of the longest lifespans at more than 100 years
Then add the following (just after "Whale sharks (Rhincodon typus) may also live over 100 years"):
Earlier estimates suggested the Greenland shark (Somniosus microcephalus) could reach about 200 years, but a recent study found that a 5.02-metre-long (16.5 ft) specimen was 392 ± 120 years old (i.e., at least 272 years old), making it the longest-lived vertebrate known.
