It lives on deep-sea hydrothermal vents. Cocoons are small, lemon shaped and yellowish gold colored. Describe flatworms and roundworms? Population genetics data indicate the occurrence of a microscale level of population differentiation that does not increase with increasing geographical distances, thus suggesting the occurrence of a metapopulation-like system and/or the possibility that enzyme loci evolve under stabilising selective driving forces inherent to the vents’ highly variable conditions. The cocoons then close and fertilization takes place. Some hermaphroditic round worms reproduce by exchanging sperm. This animal is 2 inches (5 cm) long. Red worms eat lots of organic material, but these ravenous little eating machines are particularly fond of some naturally sweet food treats.

The functional role of dominant epibiotic bacteria is discussed in the light of recent biochemical and molecular data: the tube-worm–bacteria system can be considered as a symbiotic entity where carbon is probably metabolised and recycled. How do Pompeii worms reproduce? The chemosynthetic bacteria within the trophosome convert nitrate to ammonium ions, which then are available for production of amino acids in the bacteria, which are in turn released to the tube worm.

Temporal instability possibly also plays an important role in the ability for these worms to colonise such an extreme habitat. Once the sperm is transferred a layer of cocoon forms over their intertwined body. The microhabitat is characterised by high temporal and microscale spatial variability, with temperature values in the range of 20°–45°C at the immediate periphery of tubes but reaching higher, still undetermined, values inside the tubes. Google it. What are the release dates for The Wonder Pets - 2006 Save the Ladybug?
