The length of the shell attains 24 mm. The yellowish brown whorls are doubly carinated at the suture, below which the surface is concave to the periphery. The six longitudinal ribs are strong and crossed by raised revolving lines ; yellowish brown.[2]
Distribution
This marine species occurs off Senegal and Angola.
gollark: Also that.
gollark: The image is just 3 matrices of R/G/B values.
gollark: There are 129057189471894718247141491807401825701892912 random details and things but that's the gist of it.
gollark: Then, you just move it a little bit toward lower loss (gradient descent).
gollark: You have a big thing of settable parameters determining how you go from input to output. And if you know what the result *should* be (on training data), then as the maths is all "differentiable", you can differentiate it and get the gradient of loss wrt. all the parameters.
