A floating shimmering globule of translucent material perhaps containing some sort of larval creatures.

Oxidizing "stainless steel" release hook. Perhaps a remnant from an earlier exploratory expedition. Forming its own version of rusticles.

Deep sea fish seen over rock outcrop

Colony of small green octocorals on rock outcrop with one small colony of white corals as well.

rock outcrop with small green corals on left - a coral stalk with brisingid starfish on right.

Large red shrimp with white sponge and yellow-stalked sea anemone with small bluish white sponges covering vertical face of rock outrcop. This is one of the higher diversity life form images from the Cayman Trench expedition. Small tubeworms are also seen on the vertical rock face and perhaps small corals .

Tube worm with translucent stalked on rock to left and grayish white sponges on rock. Legs of a pycnogonid sea spider are visible as well.

A large pycnogonid sea spider with tube worm, sponges, and translucent stalked tunicate.

A variety of life on an rock outcrop including a stalked sponge, translucent white sponges, at least one tube worm, and small green octocorals (look hard to find).

A gouge in the seafloor. What could cause this?

A radial pattern reminiscent of lunar impact craters. However, probably caused by digging animals.

Radiating pattern in depression with burrow evident as well. A variety of animals plow up the seafloor and redistribute the sediment.

Large holes in the sandy sediment probably caused by burrowing animals

Closeup of large holes in the sediment.

Closeup of large holes in the sediment.

A large hole in the sediment showing the capacity of these sorts of features to disturb surficial seafloor sediments.

A large hole with what appears to be a tiny burrow at the bottom . The two red dots at the upper right are probably 10 cm apart. Thus the hole is at least a meter and probably more across.

Large holes and depressions in the sediment

A large hole within a hole. The red dots are 10 cm apart. Thus the bottom "squared off" hole is at least a 1/3 of a meter cross, while the larger surrounding hole is more than a meter across.

A holothurian on a mottled bright and dark sand sea floor.

A large stone and a mat of shells cover the bottom of a hole in the sediment.

A linear gouge in the seafloor. What does this?

A large hole in the sediment at the top of a ridge.

A large hole with a large burrow continuing downward at its bottom.

A hole with coarse shells and sediment as well as some marine vegetations covering its bottom.

Small shells at the bottom of a hole in the sediment

A series of very deep, very large holes that appear to be interconnected.

A gouge in the sea floor that appears to be relatively old.
