Meet a Bargibanti pygmy seahorse.

Of the various seahorse species studied, most are known for forming partnerships called pair bonds, which they tend to reinforce through a “daily greeting”—it’s tempting to interpret it as cuddling—during which they might entwine their tails and twirl, or shake and sway next to each other, while brightening in color. Bargibant’s pygmy seahorses probably engage in such greetings, according to Smith, based on research he’s done on H. denise.
