Walckenaeria

Walckenaeria is a genus of spiders in the family Linyphiidae. It was first described in 1833 by Blackwall. As of 2017, it contains 198 species.[1] Some males in this group have eyes set up on mounds or turrets. This can reach extremes in some members of Walckenaeria, where several of the male's eyes are placed on a stalk taller than the carapace.

gollark: Isn't a u16 a "word" anyway?
gollark: What was wrong with `u64` or something?
gollark: ```c typedef uint64_t c3_d; // double-word typedef int64_t c3_ds; // signed double-word typedef uint32_t c3_w; // word typedef int32_t c3_ws; // signed word typedef uint16_t c3_s; // short typedef int16_t c3_ss; // signed short typedef uint8_t c3_y; // byte typedef int8_t c3_ys; // signed byte typedef uint8_t c3_b; // bit```Wow, this is HIGHLY readable.
gollark: Urbit contains C code for purposes, I assume.
gollark: I do not, however, have any idea why, since I only changed the multicast address.
