CAPTIONS FOR STILL IMAGES

**8/21 log:**

Galatheid crab (possibly a Eumunida species), showing the extremely long
claws they possess that enable them to cling to the inside of the
suction sampler so tenaciously.

Photo shows close-up of photoreceptors of crab collected from 1800 feet.
The enormous size of these eyes suggests that they are adapted for
extremely high sensitivity to light.

Another species of galatheid (squat lobster) showing distinct eyeglow,
which results when light hits the reflecting tapetum behind the retina.

launch.

Zooanthid polyps under fluorescent light setting (this is the blue
image) and under white light. (2 pictures for this caption)

Fluorescent chain cat shark at about 1820' feet deep. This shark was no
more than a meter long and "posed" for a couple of minutes lying still
on the bottom near the submersible.

shark.

"disgusting hagfish" captured in Dr. Frank's trap

**8/24 log:**

Green fluorescing eyebrow of a 5 cm. frogfish collected at 1,800 ft.
deep.

Unidentified jelly with algae which appears as red balls.

Planktonic copepod, most likely Microsetella sp., with green and yellow
fluorescence.

Unknown medusa-like plankton.

**8/26 log:**

The pontellid copepod Pontella securifer. Various parts glow fluorescent
green when viewed under blue light. TOP: Note the male\'s specialized
antenna and claw on its last leg (on the right) for grabbing females.
BOTTOM: The female has an oblong sperm packet attached at her tail.

Picture 1: Jon Cohen sets up his plankton net for a 15-minute tow
alongside the R/V Seward Johnson. Picture 2: Mikhail Matz and Jon Cohen
release the collection bottle from the base of the plankton net after
the tow.

Profile of the head of the pontellid copepod Pontella securifer. Light
passes sequentially through 3 separate lenses and then hits the
photoreceptor cells. This male copepod has one antenna that is bright
orange and modified for grabbing females, while the other antenna is
transparent. Two additional eyes are visible on the dorsal(top) surface
of the copepod, each with a small red lens. Image courtesy of Dr.
Jonathan Cohen

light (top) and polarized light (bottom). Images courtesy of Edith

**8/29 Log**:

Galatheid crab with a single visual pigment, tentatively identified as
Eumunida picta

Galatheid crab with UV sensitivity. Tentatively identified as
Gastroptychus sp

**8/30 log:**

Deep-sea shrimp. Upper left hand panel shows full color image. The other
three panels show how the shrimp appears under blue, green, and red
light.

Unlike what was seen at shallower depths, this animal is not most
camouflaged at blue wavelengths (which is what occurs naturally).
Instead it actually blends with the background best at red wavelengths,
suggesting that camouflage is less important at these deeper, dimmer
depths.

Yellow zooanthids on a glass sponge. Note that, though highly
conspicuous under full light, they blend in with the sponge at blue
wavelengths. These animals have been quite interesting because they also
have bright green fluorescence and very strong green bioluminescence.
They also stung our hands when we touched them, suggesting that some of
these signals may be warnings of toxicity.

(Cannibalized Ladder Alignment Mechanism), is closed before it is
recovered from the bottom. Image courtesy of Justin Marshall.

4 companions -- each at the end of a rope tether and each rope kept taut
by a weight and pulley system that is attached to a toilet flange.

specimens for fluorescence and bioluminescence.
