Can spiders survive hot water?
Spiders play an important role in our entire ecosystem, so doing something to disrupt that is just not good at all. So, spiders can survive in hot water, but it’s all connected to the temperature and force of the water as to whether they will emerge unscathed, or not. Clearly, the best course of action is to not pour any water over them.
Do platypuses live underwater?
The Platypus stays underwater for between 30-140 seconds, collecting the invertebrates from the river bottom and storing them in its cheek-pouches.

“Flushed spiders will drown if they end up submerged in the sewer,” Jerome Rovner, a member of the American Arachnological Society, told Real Clear Science. “However, the drowning process for a spider can take an hour or more, as they have an extremely low metabolic rate and thus a very low rate of oxygen consumption.”
Do wolf spiders go in water?
Some wolf spider species can swim in the water because they are adapted to their habitat and can swim underwater and can survive in the water for up to 40 hours. Most wolf spiders have a respiratory system. They need air to survive, so they cannot survive underwater, but some can still swim above the water.

Transcript. BOB SUTER: The features of spiders that let them walk on water are primarily that they can't get wet, and secondarily that they have hairs on them that also can't get wet. That is, the surface of both at the molecular level are hydrophobic, and that means that water is repelled by them.
Are there spiders at the beach?
The beach wolf spider, or Arctosa littoralis, is most commonly found near beaches, though it can live almost anywhere in the United States and southern Canada. These spiders (pictured at top of article) are experts in camouflage, and they usually hide in the sand or under driftwood during the day.
Where do fishing spiders live?
Fishing spiders (genus Dolomedes) live around ponds, slow-moving streams, swampy areas, and other damp places. They are able to run across the surface of water much like water striders and will dive for prey, including small tadpoles or aquatic insects. A spider in this group can encase its body in an air bubble in order to submerge itself, often for several minutes.

What is the predator of a fishing spider?
One interesting predator of fishing spiders ( Dolomedes spp.) is a blue-black spider wasp called Anoplius depressipes. This wasp has specialized flattened front feet that are fringed with hairs, which allow it to walk on water just like its prey. When transporting a spider, this wasp grasps the spider with its middle or hind legs, faces forward, then extends its forelegs and uses them like water skis while it propels itself and its prey across the top of the water, beating its wings. This spider wasp sometimes dives down into water to chase its prey, since water spiders often swim underwater when frightened.
What is a longjawed spider?
Longjawed orbweavers (family Tetragnathidae) are often called “stretch spiders” because they often rest with their two front pairs of legs stretched straight out in front of them, and the last pair outstretched behind. Combined with their slender bodies and drab, variably marked coloration, they can hide easily while clinging to a blade of grass. They spin circular webs that are usually positioned fairly horizontally within a few feet of the water’s surface.
What are water striders?
Similar species: Water striders ( striders, not spiders) “stride” across the water surface and are sometimes seen in rather large groups. They are not spiders at all; instead, they are in the order Hemiptera (the “true bug” family of insects) so they are related to assassin bugs, water scorpions, assassin bugs, water boatmen, and stink bugs. Like other insects, they are easily separated from spiders by having 6 (not 8) legs.
Where do orbweavers live?
Longjawed orbweavers typically live in vegetation along a water’s edge — in shoreline shrubs whose branches overhang ponds, lakes, rivers, and streams, usually in shady places. They often live along the sides of docks and piers, too. They spin circular (orb) webs that are usually positioned fairly horizontally within just a few feet of the water’s surface, making them perfect nets for catching aquatic insects that have just emerged in their winged adult forms: mayflies, midges, stoneflies, and so on. When not in their web, many longjawed orbweavers hide under branches, railings, or other sheltered locations nearby. If they are startled, they typically drop immediately down. If they fall into the water, they can run across the surface like fishing spiders and water striders do.
When do spiders hatch?
As a general rule, spiders in temperate areas hatch from eggs in spring and spend the growing season eating, maturing, mating, and laying eggs. Female spiders are usually much larger than males and sometimes eat the males after mating. Females continue creating egg cases as long as the weather holds out. As temperatures cool in fall, their metabolism slows, and they generally die when it freezes. Egg cases overwinter, and spiderlings hatch in spring.

How often do spiders travel to the surface of the water?
The spiders travel to the surface of the water approximately once per day for oxygen. All other activities, such as hunting and breeding, occur underwater. The bubble that is connected to the spider has nitrogen inside it which causes it to shrink over time. The spider will resurface to create a new bubble.

Where do water spiders live?
The Water spider lives underwater, building a bell-shaped web between underwater plant stems. It can be spotted as it comes to the water's surface to trap air in the hairs on its body, which it takes down to fill the web, or 'diving bell' (hence its other common name of 'Diving Bell Spider'). It lives in this large air bubble during the day, and hunts at night. Mating takes place within the web retreat and the female builds a special egg chamber in which she lays and guards her eggs. Water Spiders can be found in weedy lakes and ponds, and very slow-flowing streams.

They feed on crickets, grasshoppers, ants, other spiders and various pest insects like aphids. Wolf spiders possess particularly large eyes, making them easy to identify.
