Talk:Stingray

Additions

Some of my colleagues and I were thinking about adding sections on the following criteria. What do you all think about our topics of choice?

• Venom. The venom of a stingray is held in its spine. Stingrays spine can grow in the womb. The amount of toxicity varies depending on the type of stingray. The level of toxicity decreases as the stingray reaches maturity which suggests there is less of a biological need for it as it grows in size.
• Locomotion. The stingray uses Median Paired Fins (MPF) opposed to undulations where the caudal fin is the source of locomotion. MPF provides quicker and more accurate movement needed for shallower waters.
• Respiratory System. Discuss how string rays perform gas exchange. Make note of the spiracle and its usefulness for organisms such as the ray. Also, provide labeled pictures of different structures relevant to the respiratory system.
• Jaws and teeth. Discuss the the mechanics of the cartilaginous jaws and teeth (essentially rows of flat plates) in relation to feeding habits of the sting ray and include supplementary images of the jaw and teeth.

I think this one is good to be associated in the page. Since it is already overcrowded with irrelevant ones, I will just post it here. --βritandβeyonce ^{(talk•contribs)}

Removal of "largest stingray" section

I have removed the following section: Perhaps the largest stingray ever found weighed almost 1500 kilograms (3300 pounds) and measured over 5 meters (16.5 feet) in width . It was caught by fishermen near Hainan Sanya in China."Giant 3,300 Lbs Stingray Caught by Local Fisherman." Weird Asia News 04 Aug. 2008. 26 Feb. 2009 <http://www.weirdasianews.com/2008/08/11/giant-3300-lbs-stingray-caught-by-local-fisherman/> The sourced article does not list a species and the ray in the article looks just like a manta ray which to my knowledge is the only species to approach such a size.

typo

"stings" should be "stingers" in the first section of the article

Request: In section "Feeding behavior and diet" please change "Since their mouths are on the side of their bodies" to "Since their mouths are on the underside of their bodies"

Description of edit request: changing word 'side' to 'underside' to increase accuracy of description.

Manta rays are not stingrays

I noticed that there is a photo of a manta ray included in this Wiki. Manta rays are not stingrays due to the fact that they lack a barb, therefore they are unable to sting. Manta rays are simply just rays. Manta rays are in the family Mobulidae, unlike stingrays. Ashleopold (talk) 16:13, 26 July 2024 (UTC)

No link to mobulidae in the infobox on the right.

I assume because it was once covered under mylobatidae, but now it's a distinct article, it should be included. Aristaeusapiculturist (talk) 11:03, 8 October 2024 (UTC)
