//﻿Hypsibius dujardini //
**Domain**- Eukarya **Kingdom**- Animalia **Phylum**- Tardigrada **Class**- Eutardigrada **Order**- Parachela **Family**- Hypsibiidae **Genus**- Hypsibius **common name**- water bears and moss piglets **Description** Hypsibius dujardinia are members of the phylum Tardigrada. These species can also be known as water bears or moss piglets. They are microscopic invertebrates, and their body lengths are only between 0.05-1.2mm. long. These organisms have four pairs of legs which have four to eight claws on each. Usually they live between four months to one year. However, they can survive in difficult conditions. They shut down their metabolisms which allows them to survive in extreme temperatures, pressure, and radiation for a long time. They feed on the fluids of plant cells, animal cells, and bacteria.

 **Type of Cell-** eukaryote, which means it has complex structures enclosed within membranes

**Type of Reproduction ** - sexual, which means it can form new individuals

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 110%;"><span style="color: #88d83b; font-family: Tahoma,Geneva,sans-serif;">**Habitat-** They can be found in wet areas such as in a film on water on linches and mosses. They can also be found in sand dunes, soil, sediments, and leaf litter

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 110%;"> **Heterotroph or autotroph?-** <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 110%;">It is a heterotroph, which means it is a  n organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition. They feed on cells and bacteria. =====

<span style="color: #000000; font-family: Tahoma,Geneva,sans-serif; font-size: 110%;">Some of the organisms live in hot springs and live on the bodies of other organisms. They use a needle or a stylet to pinch the walls of plant cells. They feed on the liquid inside, it helps the organism because they are getting rid of dead tissues.
