Annelida/PolychaetaThe Giant Tube Worm!!

1. Allopatric speciation. The differentiation of geographically isolated populations into distinct species

2. Benthos. Organisms that live associated with the sea bottom.

3. Disturbance. A rapid change in an environment that greatly alters a previously persistent biological community.

4. Endosymbiotic. Being symbiotic and living within the body of an individual of the associated species.

5. Epibenthic (epifaunal or epifloral). Living on the surface of the bottom.

Vocabulary & Definitions

3 species are ragworms, earthworms and leeches.1. Annelida worms Can survive being frozen if not

froze to rapidly.2. Some aquatic annelids have thin-walled,

feathery gills through which gases are exchanged between the blood and the environment.

3. Adult annelid worms range from >1/2 inch 22 ft.

Species in Annelida/Polychaeta class

tubular bodies with a long red plumeThe body plan: no mouth, no digestive track,

no eyes, and the outer shell is made of chitin which is the main exoskeleton of shell fish.

Characteristics of The Giant Tube Worm

The giant tube worm lives at a minimum of 1 mile below sea level. They are most commonly found in the south pacific.

They are most commonly found in the intertidal and pelagic zones, at a temperature at around 28 degrees Fahrenheit.

They live in and around hydrothermal vets.

Habitat

Symbiotic bacteria. the giant tube worm relies on this to obtain the energy it requires for growth and development.

The bacteria in the tube worms body convert the chemicals from the hydro thermic vent like sulphide into organic material to use as food.

The giant tube worm is a heterotroph, and it is a herbivore.

Deep sea crabs and shrimp feed on the worms re plume. The crab has adapted to climbing up the worms outer shell to get to the plume, and its massive pinchers used to pick pieces off.

Shrimp have Sharp teeth

Feeding

The Giant tube worm has two major defense adaptions.

1. Its shell has doubled in with, so it would be a lot harder for a predator to get past it.

2. Another is speed. The worms can retract their plume into the safety of their shell in a second if they feel in danger.

Defense Adaptations

The giant tube worm is not mobile.They are cemented into the rock bed.

Movement

• An adult Giant Tube Worm will remain in one spot for its entire life.

• This species of worm can survive water pressure around 2,000 pounds per square inch.

• The female tube worms produce and release eggs that are rich in lipids into the water, which then float upwards.
