Aquatic insects or water insects live some portion of their life cycle in the water. They feed in the same ways as other insects.Some diving insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete.
Aerial predators of the Atlantic puffin include the great black-backed gull (Larus marinus), the great skua (Stercorarius skua), and similar-sized species, which can catch a bird in flight, or attack one that is unable to escape fast enough on the ground. On detecting danger, puffins take off and fly down to the safety of the sea or retreat ...
Similar to adaptation in avian flight, swimming behaviors in fish can be thought of as a balance of stability and maneuverability. [7] Because BCF swimming relies on more caudal body structures that can direct powerful thrust only rearwards, this form of locomotion is particularly effective for accelerating quickly and cruising continuously.
A great cormorant swimming. Aquatic locomotion or swimming is biologically propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, amphibians, reptiles, birds, and mammals.
The tufted puffin (Fratercula cirrhata), also known as crested puffin, is a relatively abundant medium-sized pelagic seabird in the auk family (Alcidae) found throughout the North Pacific Ocean. It is one of three species of puffin that make up the genus Fratercula and is easily recognizable by its thick red bill and yellow tufts.
Horned puffin burrows are usually about 1 meter (3.3 feet) deep, ending in a chamber, while the tunnel leading to a tufted puffin burrow may be up to 2.75 meters (9.0 feet) long. The nesting substrate of the tufted and Atlantic puffins is soft soil, into which tunnels are dug; in contrast, the nesting sites of horned puffins are rock crevices ...
The latter group swim slowly, but can turn rapidly, as is needed when living in coral reefs for example. But they can not swim as fast as fish using their bodies and caudal fins. [1] [2] Skeletal anatomy of Tilapia [3] Consider the tilapia shown in the diagram. Like most fish, the tilapia has a streamlined body shape reducing water resistance ...
Coyotes can easily reach 48 km/h (30 mph), and can sprint at 65 km/h (40 mph) when hunting. [99] Even without a front foot, a coyote can still run at around 32 km/h (20 mph). [98] Big brown bat (flight) 56–64 km/h (35–40 mph) Big brown bats are reported to be one of the fastest bats reaching speeds of up to 40 mph. [101] Common dolphin
