Talk:Tradeoffs for locomotion in air and water

Untitled

The title for this article leads one to believe that it is going to focus primarily on animals that can move in both air and water. The article however appears to spend more time on birds that have given up moving in air in order to move only in water. I think a rename with new sections based strictly on animals by locomotive strategy would be appropriate. Beach drifter (talk) 19:09, 5 May 2010 (UTC)

It would be interesting to discuss or at least mention non-bird/fish swim/flyiers. Flying squid, or perhaps swimming beetles. I don't know how exactly one would want to scope this article. — Preceding unsigned comment added by 71.46.235.82 (talk) 18:48, 21 February 2013 (UTC)

Another example: hatchetfishes

Hatchetfish are another fish with the ability to locomote in the air. The article on Thoracocharax claims they can literally fly by flapping the pectoral fins. Worth adding? — Preceding unsigned comment added by IAmNitpicking (talk • contribs) 16:57, 31 March 2016 (UTC)

Flying Squid

Most medium-sized pelagic squid are capable of aerodynamic flight using jet propulsion and forming their arms into a wing. Indeed, even smaller Humboldt squid do this although adults may not be able to reach their stall speed on jet power, instead only being able to engage in ballistic rocket-propelled locomotion above the waves.

There should be a section on the compromises of flight-capable squid. — Preceding unsigned comment added by 71.237.249.230 (talk) 11:30, 10 February 2019 (UTC)

Thrust direction

About image File:Lift-force-en.svg (used here). Why is the thrust-arrow not aligned with the wing centerline (ie, exactly the forward direction of the yellow wing)? -DePiep (talk) 10:43, 29 September 2019 (UTC)
