The diverse deep-sea communities of our New Zealand seamounts

The diverse deep-sea communities of our New Zealand seamounts, showing the branching corals (e.g., Solenosmilia variabilis), venus flower basket sponge (Symplectella sp), crinoid sea lilies, hydrocorals and two orange roughy on Ghoul Hill, around 1000m deep. The branching corals provide a 3D habitat for fish and invertebrates. Credit: NIWA
