As Northerners soak up the summer solstice sun, we’re reminded that the ocean has its own creatures who add a glow to seas below. Rob Spray snapped this lovely pic of a colony of Lightbulb Sea Squirts, nicknamed for the way they seem to emanate light. These sea squirts are actually transparent zooids whose larvae swim upward toward the ocean surface’s light when they are released, before settling back to the seabed.
