I believe the "Undistinguished Sabertooth" (Odontostomops normalops) to be quite distinguished. The enormous teeth work to ensure prey capture - they eat other fish. This specimen trawled from between 200m depth and the surface at night, Gulf of Mexico-August 2016.

A Netdevil (Linophryne sp.)- esca detail is in the upper right hand corner, "beard" detail in the lower right. The fish makes the beard glow by way of intrinsic bioluminescence; bacterial symbionts make the esca or "lure" glow by way of bacterial bioluminescence.

Have seen some beautiful deep water amphipods on research trips out on the Gulf of Mexico. This species lives on jellyfish. Trawled from the Gulf of Mexico between 1,500 and 1,300m depth, August 2016.

The Orangeback Flying Squid (Sthenoteuthis pteropus). This species can jump out of the water and glide, just like flying fishes.

This "Barbeled Dragonfish" (Leptostomias bilobatus) has a spectacular barbel. If you look at the magnified barbel to the bottom of the composite image, there are a couple of lobes to the barbel, highlighted in pink. One is tiny, the other the entire end of the barbel.

The deep-sea or oceanic anglerfishes comprise 11 families of the superfamily Ceratioidea. Female anglerfishes have a first dorsal ray modified into a "fishing rod" - the illicium, and the "lure" at the end of the rod that accommodates bioluminescent bacteria - the esca.

The esca is an amazing structure that provides a perfect environment for the symbiotic bacteria that live there. But the complexity of these structures is outstanding in that there are tissues in place to redirect and even contain the light produced by the bacteria.

Here are a few fun shots that highlight the escas of deep water anglerfishes from the Gulf of Mexico.

(Possibly Gigantocypris sp.) - Ostracods are crustaceans, related to crabs, shrimp, lobsters, etc. The individual here is brooding eggs (or is "in berry"). Specialized eyes detect bioluminescence in the copepods that they hunt and eat. From the DEEPEND-RESTORE Project.

This is the leptocephalus of Bristletooth Conger (Xenomystax congroides).

Murray’s Blind Lizardfish (Ipnops murrayi) -As larvae, the species is pelagic (living in the water column rather than down on the sea floor): early stage larva (top) to older larval fishes (progressing downward, middle fishes) to an adult, bottom and right).

Pacific Portholefish (Diplophos taenia) are found down to 850m depth. They employ counterillumination as their ventral photophores (light producing organs) produce light and shine that light downward – effectively eliminating the silhouette from the fish to predators looking up

The "Little Tunny" is a tuna (Scombridae). The species ranges through the Mediterranean, the eastern Atlantic, the western Atlantic (including the Gulf of Mexico and the Caribbean). Described as "opportunistic predators," they feed on anything they can fit into their mouths.

A catfish is in the genus *Mastiglanis* (Siluriformes: Heptapteridae)- spends daytime hours buried in the sand with the eyes exposed, foraging for food at night by propping themselves up on their long fins (like a tripod) and waiting for small invertebrates to pass

A Texas Coralsnakes (Micrurus tener)-a "partially amelanistic" individual. The places that should be black are taupe or grey, not pink

A composite image of pellagic, deep-sea, alciopid worms (polychaeta: errantia: phyllodocida: phyllodocidociformia: alciopidae). These species have beautiful eyes; these individuals were trawled from between 600m and the surface, Gulf of Mexico.

Threadfin Dragonfish (Echiostoma barbatum) has a bioluminescent lure that dangles at the end of a short rod (a barbel) attached to its chin. The massive teeth of this species are used to grip prey items. Several series of photophores run the length of the body on this species
