Use of bubble nets by dolphins

There was a scene in BBC's Blue Planet series that showed dolphins using bubble nets to catch sardines. Is this enough evidence to include dolphins in this article? 97.113.230.96 (talk) 01:19, 26 November 2022 (UTC)[reply]

Qustions

Hain et al.(1982) is referenced by some sentences in this article. But,

(1) "During this feeding season humpback whales actively feed for up to twenty-two hours a day." : Hain et al.(1982) have described "twenty-two hours a day" nowhere in their article.

(2) "They do this so they can store enough fat reserves to live through their breeding season when they do not eat at all." : It may be true, but it also haven't mentioned by Hain et al.(1982).

(3) "This behavior is not instinctual, it is learned; not every population of humpbacks knows how to bubble net feed." : Hain et al.(1982) have said "a given humpback whale will generally repeat a fairly rigid feeding pattern", but it doesn't mean it caused by learning or instinct.

(4) "Humpback whales use vocalizations to coordinate and efficiently execute the bubble net so they all can feed." : Hain et al.(1982) have described "The whale sounds, ...", but it's made by flukes, not vocalization. Hain et al.(1982) haven't mentioned about vocalization.

(5) "One whale will sound a feeding call, at which point all whales simultaneously swim upwards with mouths open to feed on the trapped fish." : same as above

(6) "As the whales swim up to the surface to feed they can hold up to 15,000 gallons of sea water in their mouths." : Hain et al.(1982) haven't mentioned about amount of water in mouth.

They may be confused with another citations.--240B:250:50A2:33F0:65E7:46C:52D9:C29C (talk) 06:53, 31 January 2024 (UTC)[reply]
