Some females shed their cuticle and then lay their eggs inside to be fertilized later by males.Įggs take around 40 days to hatch, or as long as 90 days if they’ve been in a desiccated state. In some species, males deposit sperm inside the cuticle of a molting, egg-carrying female during an hour-long mating process. Depending on the species, the animals may reproduce asexually or sexually. Naturally, tardigrades have unusual mating habits, too. When conditions improve, they unfurl themselves and go about their business. The micro-animals squeeze all the water out of their bodies, retract their heads and limbs, roll up into a little ball, and become dormant. Their resiliency is in part due to a unique protein in their bodies called Dsup-short for 'damage suppressor'-that protects their DNA from being harmed by things like ionizing radiation, which is present in soil, water, and vegetation.Īnother amazing survival trick is cryptobiosis, a state of inactivity triggered by a dry environment. They can also live at temperatures as cold as absolute zero or above boiling, at pressures six times that of the ocean’s deepest trenches, and in t he vacuum of space. For instance, tardigrades can go up to 30 years without food or water. Tardigrades belong to an elite category of animals known as extremophiles, or critters that can survive environments that most others can't. They have four to six claws on each foot, which helps them cling to plant matter, and a specialized mouthpart called a bucco pharyngeal apparatus, which allows them to suck nutrients from plants and microorganisms. These amazing insects, ' as Sir minute French roll, a harp and a spindle, a weaver's Emerson Tennent calls them, can scarcely be distinshuttle, a music. Like those insects, tardigrades have to shed their cuticles in order to grow.

Freshwater mosses and lichens are their preferred habitat, hence their nickname, moss piglet.ĭespite looking squishy, tardigrades are covered in a tough cuticle, similar to the exoskeletons of grasshoppers, praying mantises, and other insects to which they are related. Considered aquatic because they require a thin layer of water around their bodies to prevent dehydration, they’ve also been observed in all kinds of environments, from the deep sea to sand dunes.
