Polychaete Worms

Polychaete Worms

Many of these worms are known as polychaetes - meaning ‘many bristles’, due to the fact that each body segment has a pair of fleshy protrusions called parapodia that are covered in bristles, called chaetae. Found in nearly every corner of the deep, polychaetes rule the sea, and play a vital role in the deep sea ecosystem.

At the towering, rocky structures of hydrothermal vents, we find one particular polychaete worm that has adapted to rely entirely on the vents. This is a Pompeii worm. An extremophile, and the most heat-tolerant animal on Earth, that is found only at hydrothermal vents in the Pacific Ocean. They form heat-resistant tube colonies attached to the vents, within which they reside. But what’s most unique about this worm, is the fact that their tail end rests within the superheated vent fluid at 80º C (176º F), while their feather-like heads stick out of their tubes into water that is far cooler. The advantage of doing so is that it allows Pompeii worms to form a symbiotic relationship with bacteria. The hair that lines their body is actually a thermal blanket of colonies of filamentous bacteria.

The bacteria is kept alive as the Pompeii worm secretes an enzyme-rich sugar mucus from its back to feed them. In return, the bacteria act as insulation, and as detoxifiers of the vent fluid in the worm’s tube, converting the lethal chemicals into energy that the worm requires in order to survive.

But unlike many creatures that dwell at deep sea vents, polychaete worms are abundant also in the open expanse of the deep, where they instead survive by feeding on plankton and marine snow that drifts down from above. Some secrete a giant mucus net around themselves in order to do so. Here in the midwater zone, far from both the surface and the sea floor, polychaete’s adaptations appear even more unique. Flota and swima worms both move by undulating their bodies and beating their paddle-like appendages. Far stranger is tomopteris - the dancing bristle worm - which propels itself with its large parapodia.

A common feature is that many of the worms that inhabit the open ocean are transparent. This is because there is no concealment in the midwater zone, and so some worms like the green bomber worm have adapted to use bioluminescence as a way to startle and distract predators. When threatened, they explode their light-producing organs called photophores, dropping a kind of bioluminescent bomb.

Inevitably, when these drifting worms die, or release their large mucus nets, the organic material sinks to the sea floor. But there are polychaetes there, too, feeding on this nutrient-rich supply. Every now and then, they are treated to a feast. When the carcass of marine mammals sink to the ocean floor, a whale-fall community rapidly gathers that can last for 50 years. But for the majority of this time period, it is not the large scavengers that make up this diverse community. Once the flesh has been stripped, it is the polychaetes that remain, possessing the ability to get at the otherwise inaccessible nutrients locked away within the bones. Specifically, this is the job of the bone-eating osedax worms, or zombie worms. With their deep, green roots they bore into the bones of the whale carcass to reach the lipids within, on which they rely for sustenance. In doing this task, osedax worms carry out the important role of cycling nutrients back into the deep sea ecosystem.

There you have it. The rulers of the deep, the polychaete worms, capable of colonising every corner of this harsh and barren landscape. Found burrowing into the mud, clinging to rocky seamounts, colonising vents and eating dead whales, these worms play a fundamental role in the deep sea ecosystem as detrivores, symbionts, and a source of nutrients for predators.

Into the Midnight Zone: Secrets of the Ocean Void

The Deep Sea Midnight Zone | Worlds of the Deep, a collaboration with Schmidt Ocean Institute. Thank you to Brilliant for sponsoring Natural World Facts 🧠💡 - for a 30-day free trial and 20% off an annual premium subscription visit https://brilliant.org/NaturalWorldFacts/ In the deep ocean, life is divided between very different worlds. In the midwater, pelagic wanderers tread migratory routes that span entire oceans, and planktonic drifters and their predators take part in bioluminescent light shows. It is separated into zones based on depth, including the sunlight zone (epipelagic), twilight zone (mesopelagic), midnight zone (bathypelagic), abyssal and hadal zones. And below, lies the deep sea floor. A kingdom of mud and ooze, where sessile creatures cling to any solid outcrop and corals craft kingdoms on the seamount crusts. The worlds of the deep sea could not be more different, and yet their stories are fundamentally intertwined. In this episode, we delve into the Midnight Zone, a pitch-black zone of the deep sea where life has found peculiar ways to survive the immense pressure, from anglerfish to vampire squid to giant sharks.

The experience closes on January 27th at 11:59pm PST and I promise, you don’t want to miss this! Deep sea (abyssal) gigantism demonstrates the role of natural selection in driving evolution and survival, particularly in an environment characterised by challenging conditions and limited resources. Evolution tends towards the most effective adaptations to grant animals the best chances of survival. And whether large or small, evolution selects for the best-adapted body size to survive these conditions. Though widely debated and often controversial, the research that has been done into the science behind deep sea gigantism has significant implications in the human world; it is believed that climate change may have a greater impact on ocean dwellers than any other population of animals. As the colder oceans warm up, the balance of temperature, oxygen supply, and what organisms are present, will throw the equilibrium off course. And the giants, which rely so heavily on this fine balance, may be the first to go.

Deep-Sea Food Falls | A Tale of Wood and Bone

Chemosynthetic Oases | Deep Sea Food-Falls and Wood-Falls. The first 100 people to download Endel by clicking the link below will get a free week of audio experiences! https://app.adjust.com/b8wxub6?campaign=naturalworldfacts_june&adgroup=youtube The degradation of food-falls at the bottom of the ocean can create partially chemosynthetic environments. In the case of sunken whale carcasses (whale falls), the supply of organic material supports an ecological succession of communities. But perhaps less well-documented than the scavengers at whale-falls are the creatures that rely on wood instead. When trees become uprooted by storms or ships capsize at sea, losing their buoyancy as the pressure of the ocean forces out any air trapped within, bits of wood sink to the ocean floor where they create fleeting oases of life (wood falls), including shipwrecks, like that of the Titanic. The scarcity of food in parts of the deep ocean creates an environment where very little goes to waste. The animal and microbial life that dwells down here has become resourceful, able to make the most of even unexpected resources. So it comes as no surprise that the deep ocean hosts complex biological communities adapted to thrive on this sunken wood.

Robots in the Deep Sea (ft. Schmidt Ocean Institute)

Exploring life in the deep-ocean midwater is a long-standing challenge for deep-sea research. The region between the surface and sea-floor, a space that constitutes the largest most biodiverse habitat on Earth, remains poorly understood due to the limitations of sampling its gelatinous, fragile inhabitants. Robots in the Deep documents recent innovations that allow midwater animals to be sampled in-situ, non-intrusively, with greater efficiency than ever. ROVs and new sampling systems are opening a window onto midwaters which, during these times of uncertainty surrounding deep-sea exploitation and its impacts, is crucial to how we approach stewardship in our planet's last frontier. Created in collaboration with Schmidt Ocean Institute. Written, narrated and edited by Leo Richards. Produced by Logan Mock-Bunting. Featuring interviews with: Brennan Philips (University of Rhode Island) Kakani Katija (MBARI) Peter Girguis (Harvard University) Schmidt Ocean Institute: https://www.youtube.com/c/SchmidtOcean/featured This film is being entered into the Jackson Wild film festival as a student entry. 00:00 - Introduction 01:25 - Meet ROV SuBastian 02:54 - Exploring the Auka Vent Field 04:55 - Sampling the Deep Midwaters 08:01 - Remote Imaging Systems 09:33 - In-Situ Sampling 10:19 - Digital Holotypes 11:52 - Pushing the Envelope 12:25 - Outro #worldoceanday #deepsea #wildlife #nature #documentary #ocean #marinebiology #science #biology
