When sea urchins die, they leave behind their 'test', which is essentially a skeleton.
#Urchins and their tests come in many forms. Here, a selection of three urchins – (L-R) Microcyphus zigzag, Goniocidaris tubaria, and Protenaster australis – demonstrate this incredible variety.

Beneath their spiny exterior, #urchins are immaculately sculptured.
Here is a composite showing the urchin species Holopneustes purpurascens, both alive and in its skeletal state.

Kerunia cornuta is a hydrozoan fossil that lived in Wadi Hitan of Egypt 40 million years ago. From this view, its shape resembles the ankh, the famous symbol of life in ancient Egyptian times.

A daffodil inside.
The faint yellow and orange of a daffodil abstracted by condensation on the glasshouse window, brought into sharper focus in some of the larger drops.

Why Pigeons Make Bad Nests: A defense of pigeon aesthetics
A six-panel comic. In panel 1, there's a pigeon standing awkwardly next to a pile of sticks with two eggs on it, and the panel is titled "Why pigeons make bad nests: A defense of pigeon aesthetics." In panel 2, a pigeon sits on a pile of sticks: "Many people think that pigeons are bad at making nests. Here are three good reasons why pigeon nests look bad." In panel 3, there's "Reason 1: Some birds, like orioles, nest in tree branches, so they weave elaborate structures that can withstand the elements..." And there's a female Baltimore Oriole weaving an elaborate hanging nest in a silver maple tree. In panel 4, "...but rock pigeons evolved to nest in crevices in cliffs, safely tucked away." And there's a pigeon sitting on a nest in a hole in a cliff. In panel 5, "Reason 2: People domesticated pigeons ages ago. Pigeons didn't need fancy nests because they had human-built homes." A beautiful dovecote shelters a flock of pigeons. In panel 6, "Reason 3: Less time making nest = more time eating seed." A pigeon pecks a seed near its nest, and says "It's called math."
