The Squid-Worm's Scientific Classification
Classification

Annelida

Polychaeta

Sedentaria

Canalipalpata

Terebellida

Cirratuliformia

Acrocirridae

Teuthidodrilus

Samae
Kingdom: Animalia
The Squid-worm can be considered part of the Kingdom Animalia because it is a living creature that interacts with other living things and maintains homeostasis.
Phylum: Annelida
Requirements to be a member of Phylum Annelida:
Bilaterally symmetrical
Body has more than two cell layers
Body possesses 3 separate sections; a prosomium, a trunk and a pygidium
Has a closed respiratory system
Feeds on a wide variety of materials
Can live in most environments

The Squid-worm fulfills these requirements!
Order: Terebellida
Terebellida are 'bristle worms'. They can often live in extreme water environments.
The Squid-worm
Was it a squid? Or a worm? When discovered, this new species so perplexed "Census of Marine Life" researchers that they simply called it Squid-worm. With bristle-like "paddles" for swimming and with tentacles on its head, it was found about 1.7 miles under the Celebes Sea, which is near Indonesia, in 2007. The four-inch-long creature turned out to be the first member of a new family in the Polycheata class of segmented worms; its scientific
name is
Teuthidodrilus samae,
and it eats "marine
snow", which is a mix of sinking microscopic
plants, dead animals, fecal material, and cast-off
mucus.

Family
Genus
Species
Class: Polychaeta
The class Polychaeta's organisms have:
A well-developed head
Lateral appendages called parapodia
Large number of respiratory capillaries
May be particle feeders
Subclass: Sedentaria
Other creatures in Kingdom Animalia
include Lions, BlueBirds, and dolphins.
A well-known Annelid is the Earthworm
A well-Known Polychaete Worm is the fan worm.
Infraclass: Canalipalpata
Subclass Sedentaria is a subclass
of purely marine worms which are either burrowers or tube-dwellers.
Infraclass Canalipalpata's members have no teeth or jaws. Most are filter feeders.
Spaghetti Worms are members of Sedentaria and Canalipalpata.
Suborder: Cirratuliformia
A popular Terebellidian member is the Pompeii worm.
Cirratuliformian creatures have one or more pair of grooved palps on one or more segment of the body. A palp is a pair of long segmented appendages near an organisms mouth, usually pertaining to touch or taste.
suborder Cirratuliformia Boasts the Flabelligeridae.
Family: Acrocirridae
Genus:
Teuthidodrilus
"Acrocirrids are detritivores (deposit feeders), catching falling particles with numerous long tentacles (NatureWatch)." They are mainly sea-bed dwelling creatures, but a few have adapted to be able to swim.
The Acrocirrid 'Green Bomber Worm'
Teuthidodrilus
is unique as it is believed to be a transitional organism, with characteristics of both sea-bed dwelling and free-swimming organisms.
Teuthidodrilus
is closely related to the Swima genus.
Swima
Teuthidodrilus
Species: Samae
The Squid-worm's second half of its scientific name was given it in honor of the Bangsa Sama people who live in the region surrounding the initial discovery site of the squid-worm.

The
Teuthidodrilus samae
(Squid-worm) is currently the only species in the
Teuthidodrilus
genus.
