What are the similarities between a sea urchin and a street urchin?

The word originally meant "hedgehog", you can see how that then gets to sea urchin.  Was used informally in medieval times to describe people whose appearance was hedghog-like, and over time to anyone who looked rather scruffy.

Leaf dragons are gorgeous fish! The leaf dragon is better known as leafy sea dragon.\nThey're relatives of the seahorses and pipefishes, and actually look like extremely well camouflaged seahorses. Their bodies have excrecences that simulate underwater algae and slowly move with the water, so that they seem like masses of plants just drifting by, similar to the sea weeds.\nIn other respects, their characteristics and biology are the same as other seahorses (Family Syngnathidae).

Yes it is very similar, because the norns and the fates are almost the same people, but there are enough differences in those 2 myths to make it a good comparison.

The Great White Whale like Moby Dick?\n\nThe "Great White Whale" of Melville's novel, if such an animal existed, was an albino, and white sperm whales have been reported in reality as well.

1. Studies show that during the development of the embryo, it takes different forms that "recap" the evolutionary process that has produced the animal which is about to be born. For instance, during human embryogenesis, foetus exhibit a tail, a feature that our distant ancestors have had.\n\n2. No, they do not share structural similarities. So they are not closelly related.\n\n3. It's convergent evolution: even though both organs have different origins (a fin is a bone projection, while the flipper is the equivalent of our arms), evolution tried to satisfy the same need : to move in water.

They are cousins.  The cuttlefish has a cuttlebone, the squid does not.

I'm partial to crabs. They are misunderstood. Each one has their own personality and temperament. Some even do tricks. It's a shame we execute them so quickly upon discovery.

You could compare the tides to slow, regular breathing and tsunamis to sneezes, I guess. You could say the moon is the little sister to Earth. I can't think of any analogies for the others.\n\nSince the moon causes the tides, waves batter cliffs and you are safe from waves in a bay, there is probably some grand, unifying metaphor here, but it escapes me. Sorry.

they are *extremely* different kinds of plants, so the only similarities would be that their flowers have petals, stamens and ovaries
