The interior of the brood chamber of a sponge, Amphimedon queenslandica, showing embryos in the early phases of development. Though the slow moving purple sea urchin may look oblivious, lacking a head, eyes and ears, this prickly creature has an impressive suite of sensory receptors to detect outside signals. And don't overlook this animal's self-defense abilities: it has much more ammunition to activate its innate immune system than humans have. The starlet sea anemone lives in coastal areas that face increasing pollution, and it is better equipped than many land, ocean, and freshwater animals to tolerate environmental stress.
