Swimming animals that are denser than water must generate lift or adapt a benthic lifestyle. Movement of the fish to generate hydrodynamic lift is necessary to prevent sinking. Often, their bodies act as hydrofoils, a task that is more effective in flat-bodied fish. At a small tilt angle, the lift is greater for flat fish than it is for fish ...
The tails of tuna move fast enough to cause cavitation, which slows them down as vapour accumulates. [3] Tuna have bony fins without nerve endings, which prevents the fish from feeling the pain of cavitation but does not fully protect them from the implosive damage. Shortfin mako shark: 72 km/h (45 mph) [citation needed] [dubious – discuss]
The liger is the offspring of a female tiger and a male lion and the tigon the offspring of a male tiger and a female lion. [45] The lion sire passes on a growth-promoting gene, but the corresponding growth-inhibiting gene from the female tiger is absent, so that ligers grow far larger than either parent species.
In zoos, lions have been bred with tigers to create hybrids for the curiosity of visitors or for scientific purpose. [39] [40] The liger is bigger than a lion and a tiger, whereas most tigons are relatively small compared to their parents because of reciprocal gene effects. [41] [42] The leopon is a hybrid between a lion and leopard. [43]

After spending 60 days inside the reserve, Yadav finally got this image of a young female tiger, one of just a few photos captured of the black tigers. To see all 20 of National Geographic's ...
Here's how Baloo the bear, Leo the lion and Shere Khan the tiger met. "13 years ago, the trio of cubs was found in an Atlanta drug dealer's basement." The cubs were found in terrible condition ...
Lionfish are known for their venomous fin rays, which makes them hazardous to other marine animals, as well as humans. [4] Pterois venom produced negative inotropic and chronotropic effects when tested in both frog and clam hearts [32] and has a depressive effect on rabbit blood pressure. [33] These results are thought to be due to nitric oxide ...
