A Bobtail Squid (Heteroteuthis dagamensis)

Moonfish (Selene sp.)

Another immature shrimp from this morning's trawl...perhaps an Atlantic Coral Banded Shrimp?

So folks ask me all the time about the size of the deep water wildlife we see. Most are really small. One exception can be found with several species of dragonfish (this is Echiostoma barbatum). Pictured here is Katie Bowen with the dragonfish.

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

A "Swallower" (Pseudoscopelus sp.) - they have greatly expandable stomach tissue and can eat fish twice their size. Also called a "Snaketooth."

Catch of yesterday morning...a lobster larvae.

Another encounter in the afternoon trawl. A Dragonfish (Idiacanthus fasciola). This Dragonfish is sexually dimorphic. Males don't get the barbel and bioluminescent bulb hanging off of their chins. They have short lives and last just long enough to breed. This is a female. Note the bioluminescent photophores on her sides. Those spots glow in the dark and most likely aid in recognition of same species individuals and even recognition between the sexes. The bulb at the end of her barbel glows and attracts her prey items.

A deep water fish (Scopelarchus analis) with upward facing eyes that are adapted to see faint light or to key in on bioluminescence.
