Description

Shell

Teralatirus roboreus has a small (~10 mm), spindle-like, richly-sculptured, uncompressed shell. Adult specimens usually have seven convex whorls in total, with an inconspicuous suture, and a tall, conical spire that corresponds to 3/4 of the total shell length.[2] The apex bears a large, inflated, dome-like protoconch with two whorls and a characteristic sculpture pattern. It initially has a smooth surface (1/3 whorl), which suddenly becomes ornamented by a series of strong axial ribs. By the second whorl, it gradually changes into a net-like pattern of axial ribs and spiral cords, bearing small nodules at the intersections. This intricate sculpture is absent in the teleoconch whorls, which are solely sculptured by strong, rounded spiral cords. The aperture outline is elliptical, with a thickened peristome and a well-marked callus. The columella bears two strong folds, and the canal is short and curved. The shell is colored light orange to dark-reddish brown, with a usually darker protoconch.[2]

Distribution

This species occurs in the Western Atlantic, from Antigua, Barbados and the Lesser Antilles to Brazil. it is usually found under coral slabs in shallow waters.[2]

gollark: Actually, for Ryzen it has a significant performance impact because the DRAM speed controls the infinity fabric speed.
gollark: I "fixed" the problem by fully downgrading my system to the package versions of about a week ago, adding everything with "qt" in the name to the "do not update" list, and updating again.
gollark: There's a relevant bug report but it just says "Fixed" and is closed, with the comment "plasma-integration 5.7.5-2/5.7.90-2 ", and others got closed as duplicates.
gollark: How I hate dynamic libraries.
gollark: I ran a broken program in `gdb` and this happened?```Program received signal SIGSEGV, Segmentation fault.0x00007ffff7fde4c1 in _dl_relocate_object () from /lib64/ld-linux-x86-64.so.2```
