Gallery: Life of the Costa Rica Margin Hydrothermal Seep
Beauty of a Tube Worm
Lamellibrachia barhami, a species of tubeworm that lives at both hydrothermal vents and methane seeps. This ‘foundation’ species forms giant bushes and massive meadows at Jaco Scar on the Costa Rica Margin.
Tube Worm Bush
Mussels and tube worms cluster together in enormous bushes around the Costa Rica margin 'hydrothermal seep.' Researchers estimate that more than 14,000 tube worms make up this enormous bush.
Meadows of Tube Worms
At the methane-rich hydrothermal site, tube worms dominate the landscape.
