Bolas: Bolas spiders are unusual orb-weaver spiders that do not spin the webs. Instead, they hunt by using a sticky 'capture blob' of silk on the end of a line, known as a ' bolas '. By swinging the bolas at flying male moths or moth flies nearby, the spider may snag its prey rather like a fisherman snagging a fish on a hook.
Animal echolocation, animals emitting sound and listening to the echo in order to locate objects or navigate; Echo sounding, listening to the echo of sound pulses to measure the distance to the bottom of the sea, a special case of sonar; Gunfire locator; Human echolocation, the use of echolocation by blind people; Human bycatch
Echolocating bats use echolocation to navigate and forage, often in total darkness. They generally emerge from their roosts in caves, attics, or trees at dusk and hunt for insects into the night. Using echolocation, bats can determine how far away an object is, the object's size, shape and density, and the direction (if any) that an object is ...
Animals that use sun compass orientation are fish, birds, sea-turtles, butterflies, bees, sandhoppers, reptiles, and ants. [15] When sandhoppers (such as Talitrus saltator) are taken up a beach, they easily find their way back down to the sea. It has been shown that this is not simply by moving downhill or towards the sight or sound of the sea.
Spiders that spin webs typically have three claws, the middle one being small; hunting spiders typically have only two claws. Since they do not have antennae, spiders use specialised and sensitive setae on their legs to pick up scent, sounds, vibrations and air currents. [6] Some spiders, such as the Australian crab spider, do not have claws.
Ballooning is a behavior in which spiders and some other invertebrates use airborne dispersal to move between locations. [ 4 ] [ 5 ] A spider (usually limited to individuals of a small species), or spiderling after hatching, [ 6 ] will climb as high as it can, stand on raised legs with its abdomen pointed upward ("tiptoeing"), [ 7 ] and then ...
Wolf spider. What they look like: With over 200 species of wolf spiders crawling around, it’s no wonder that they range in size and appearance.“The largest species can be up to an inch and a ...
Human echolocation is the ability of humans to detect objects in their environment by sensing echoes from those objects, by actively creating sounds: for example, by tapping their canes, lightly stomping their foot, snapping their fingers, or making clicking noises with their mouths.
