Blacksnout Seasnail
Paralipparis copei copei
The Blacksnout Seasnail may not look like a snail, but it does have a slimy, gelatinous substance that covers its body. It can be found at depths between 200 m to 1692 m, and adults grow up to be 17 cm in size (approximately 6.5 in). It also has an elongated body that resembles an eel. Furthermore, it can be seen rolling itself in a loop; this behavior is a defensive posture that makes it appear like a jelly. In the darkness, predators tend to avoid the Blacksnout Seasnail because its often mistaken as a hunter due to its appearance and behavior.
Glass Octopus
Vitreledonella richardi
The Glass Octopus spend its entire life in the midwater section of the ocean and found at depths between 200m to 2000m. Even though it has no protection from predators, it achieves perfect transparency. The only part of the Glass Octopus that is visible is its digestive gland. However, the digestive gland is placed vertically to minimize detection. In addition, I find this octopus to be super cute!

Black Dragonfish
Idiacanthus atlanticus
The Black Dragonfish are needle-like fish that migrate between 500m and 2000m in the deep ocean. Females are black with 6 stripes and lack a barbel, pelvic fins, and sharp teeth. Males, on the other hand, are dark brown and have a barbel, which is the light producing structure on its chin. Furthermore, it uses bioluminescence to detect prey instead of lure prey.

Jewel Squid
Histioteuthis heteropsis
The Jewel Squid is covered in color-changing photophores that resemble sparkling gem stones. They also have a light-red coloration and are about 20 cm in length. They display a unique behavioral adaptation called diel migration. During the day, they stay at depths around 400-1200 m, and then surface during night (0-400m). This behavioral pattern is designed maximize feeding at night, and avoid predators during the day. The primary predator of the Jewel Squid is the Sperm Whale.

Pyrodinium bahamense
Pyrodinium bahamense is a tropical species of dinoflagellates that is found primarily in Atlantic Ocean waters. It prefers salinity around 20 psu and blooms when there are large amounts of nitrogen in the water. The dinoflagellate glows bright blue when agitated by motion. Furthermore, even though this plankton species is beautiful to look at, it causes seafood toxicity.

Fangtooth
Anoplogaster cornuta
The Fangtooth is a ferocious predator that is found at depths between 600 m to 5000 m. It has large, needle like teeth that are used to catch prey. It also has extremely sensitive sensory canals underneath of its scales used to detect movement in the water. Furthermore, their preferred prey are crustaceans and fish.

Pigbutt worm
Chaetopterus pugaporcinus
The Pigbutt worm or the flying buttocks of the sea is spotted floating between 965 m to 1300 m in the deep ocean. It is actually a polychaete (polly-keet) worm species that burrows in the ground as an adult, and floats around the ocean as a baby. The worm feeds itself : by creating a balloon of mucus; collecting particles on the mucus; and then consuming the particles. It is the rarest and thickest worm in the deep ocean, for only ten have been spotted.

Physonect Siphonophore
Nanomia cara
The Physonect siphonophore has tiny, bubble shaped sacs that are filled with gas. The sacs are called pneumatophores and help this creature move through the deep ocean. It also has venomous tentacles that stun prey and over eighty stomachs. There are numerous amounts of these strange creatures along the east coast, and they have cause some fisheries to collapse. Furthermore, they can be found at depth between 400m to 1000m.
