Description

The size of an adult shell varies between 13 mm and 159 mm and has a biconical shape. The shell consists of a protoconch of 2.5 whorls and 7-8 whorls in the teleoconch. The acuminate spire is turreted. The shoulder of each whorl is somewhat tabulate, with numerous septa crossing to the sutures. The shoulder angle is somewhat coronate. The surface of the shell is finely spirally striate. The anal sinus is broad and deep. The body whorl constitutes about half the total length. The narrow aperture is sinuous. The thick siphonal canal is short and broad. The color of the shell is whitish or yellowish. Reeve has given a drawing of a reversed shell, a rarity in this genus.[4][5]

Distribution

This marine species occurs off the Philippines, in the Pacific Ocean off Indonesia and New Guinea to Japan.

gollark: For an entirely blank image, it's *weirdly* large.
gollark: 2020, mostly.
gollark: AES-128. Apioform generation. Euler's totient function. Reversing a string. 2048 (game). 2048 (number). Parse strings to integers. Text RPG (or just a character generator). Draw a Sierpinski triangle textually (or other fractal thing). Abelian sandpile model. Fibonacci sequences. Digital signal processing which is on Rosetta code for some reason. Balanced ternary. Levenshtein distance.
gollark: I was going to use experimental gollarious esolang™ 0.3 but it would have been too obvious so I just did the algorithm. But this was also too obvious?
gollark: Yes, experience 12849127489174 congratulation.
