The highest reliably measured running speed for ostriches is 61 km/h (38 mph), obtained by speedometer reading when a car was chasing an ostrich in a straight line chase to force it to move as fast as it could. [53] Although there are reports of speeds of 72–97 km/h (45–60 mph) for ostriches, none are confirmed. [54] Emu (on land)
Regardless of size of the animal, at any particular speed, maximum possible lift is proportional to (wing area) x (speed) 2. Dolphins and whales have large, horizontal caudal hydrofoils, while many fish and sharks have vertical caudal hydrofoils. Porpoising (seen in cetaceans, penguins, and pinnipeds) may save energy if they are moving fast.
The fish move upward by curving their slender body as a letter C. [5] Most of the fish jump out of water by C-start. Freshwater butterflyfish jumps out of water by curving its body. [6] The fish is known for its enlarged pectoral fins but it falls back to water instead of gliding. [6] Freshwater hatchetfish exhibits a ballistic aerial path. [6]
Because fluids are easily deformable and move in response to applied forces, efficiently locomoting in a fluid medium presents unique challenges. Specific morphological characteristics are therefore required in animal species that primarily depend on fluidic locomotion. Because the properties of air and water are so different, swimming and ...
Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about 6.8–15.9 kg (15–35 lb)) at a single feeding. Sea lions can move around 16 knots (30 km/h; 18 mph) in water and at their fastest they can reach a speed of about 30 knots (56 km/h; 35 mph). [3]
A species of mudskipper (Periophthalmus gracilis)Fin and flipper locomotion occurs mostly in aquatic locomotion, and rarely in terrestrial locomotion.From the three common states of matter — gas, liquid and solid, these appendages are adapted for liquids, mostly fresh or saltwater and used in locomotion, steering and balancing of the body.
Oceanic plants and animals easily capture what they need for their daily life, which make them 'lazy' and 'slow'. Sea water removes waste from animals and plants. Sea water is cleaner than we can imagine. Because of the huge volume of ocean, the waste produced by oceanic organisms and even human activities can hardly get the sea water polluted.
During scientific surveys with relatively fast-moving surface nets, they are caught in more than 60% of the tows (less in slow-moving tows, likely because of their ability to avoid them). [2] Studies show that densities locally can be as high as 1 individual per 19 m 2 (200 sq ft) in the oceanic species, [ 8 ] and 120 individuals per m² (11 ...
