Seahorses are amazing, beautiful creatures in my opinion. In fact, raising and breeding these fabulous creatures is on my bucket list. Here's a beautiful black stallion seahorse, and an amazing crocheted seahorse (the only kind I can have right now).
If you've ever considered seahorses, as pets or objects of beauty and interest, I highly recommend "Poseidon's Steed", by Helen Scales. Here's her web address as well: http://helenscales.com/poseidons-steed/. I've learned a lot about sea horses from her! Plus the book cover is lovely, and looks great on my shelf ;)
