# Tube Worm (*Hydroides elegans*) Tube worms are fascinating creatures that live deep in the ocean. They build long tubes out of minerals and can survive in extreme conditions where other animals can't. These worms don't have eyes or mouths but can still thrive in their unique underwater homes. - **Category:** [Invertebrate](https://www.snappit.app/explore/categories/invertebrate) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Habitat:** Deep Sea ![Tube Worm](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/%E3%82%AB%E3%82%B5%E3%83%8D%E3%82%AB%E3%83%B3%E3%82%B6%E3%82%B7.jpg&width=800) Photo: Horsehealth36, CC BY-SA 4.0 · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:%E3%82%AB%E3%82%B5%E3%83%8D%E3%82%AB%E3%83%B3%E3%82%B6%E3%82%B7.jpg) ## Appearance The Tube Worm has a hard, white, calcium carbonate tube, often coiled or twisted, with a feathery crown of colorful tentacles. Its crown can display vibrant shades of orange, red, or white, extending from the tube's opening to filter food. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Annelida - **Class:** Polychaeta - **Order:** Sabellida - **Family:** Serpulidae - **Genus:** Hydroides ## Interesting facts - Despite being stuck in one spot, their babies can swim freely to new homes. - If danger approaches, they can instantly pull their feathery head into their tube! - These worms make their own strong, chalky homes to stay safe from hungry fish. - Tube worms help keep ocean water clean by filtering tiny bits of food from it. ## Special abilities - **Tube Building Architect:** Tube Worm can quickly build a strong, protective tube made of calcium carbonate that helps them anchor securely to surfaces. - **Rapid Retreat:** Tube Worm can instantly retract its delicate feathery crown into its hard tube to escape danger. - **Regenerative Crown:** Tube Worm can regrow its feathery crown if it's damaged or lost, helping it recover from attacks. ## Measurements & details - **Length:** 3 cm - **Weight:** 0.5 g - **Lifespan:** 2 years ## Diet & Feeding These worms filter tiny plankton and organic particles from the water. - **Age differences:** null - **Primary Foods:** phytoplankton, zooplankton larvae, detritus, dissolved organic matter - **Foraging Method:** Filter feeding ## Ecological connections - **Eats:** White Sea Bream (*Diplodus sargus*) — Fish graze on their exposed feathery crowns. - **Eats:** [European Green Crab](https://www.snappit.app/explore/european-green-crab) (*Carcinus maenas*) — Crabs dislodge and consume the worms from surfaces. - **Eats:** [Sea Urchin](https://www.snappit.app/explore/sea-urchin) (*Paracentrotus lividus*) — Sea urchins can scrape and consume their calcified tubes. ## Traits - [Camouflaged](https://www.snappit.app/explore/traits/camouflaged): Camouflaged describes organisms that possess coloring or patterns that allow them to blend into their environment. - [Deep Sea](https://www.snappit.app/explore/traits/deep-sea): Deep sea habitats are characterized by extreme pressure, darkness, and cold temperatures, supporting unique life forms below the sunlit zone. - [Fossil](https://www.snappit.app/explore/traits/fossil): A fossil is the preserved remains or traces of an ancient organism embedded in rock or other geological deposits. - [Natural](https://www.snappit.app/explore/traits/natural): Natural refers to organisms, materials, or phenomena existing or produced by nature, not artificially created. ## Collections - [Marine Life](https://www.snappit.app/explore/collections/marine-life) ## Safety **Danger:** 1/5 · Very low Tube worms live in the deep ocean where it's not safe for humans to explore. It's best to admire them from pictures or videos. ## Frequently Asked Questions ### How to identify Tube Worm? Look for fins, arms, tentacles, shells and body symmetry.
