Teuthidodrilus

Seven specimens were observed and collected from the deep-water column of the seafloor) of the Celebes Sea near the Tawi-Tawi islands of the Philippines.

A similar undescribed and uncollected specimen observed from off western India by the Hercules 7 ROV in 2004 may represent a second species in the genus.

They are arranged along the upper and side ridges of the head, arising from the pair of feather-like nuchal organs which analyze chemical signals in the sea.

The fifth pair of appendages are grooved and coiled feeding palps arising from below the mouth, which is located in the front-bottom corner of the head.

The female gonads are located in the second to fourth segments with beige-colored grape-like clusters of variously-sized ova (with a maximum diameter of 1 mm (0.039 in)).

It is categorized as a suspension eater since it consumes marine snow, which consists of pieces from animals, plants, feces and other organic materials that precipitate from the higher parts of the ocean towards the abyss.

[1][5] In total, sixteen specimens were observed and seven were collected within just a few dives suggesting that this animal is a common member of the benthopelagic community of the Celebes Sea basin.
