edit from ohscience: Nat Geo says: “Coral polyps can reproduce asexually, forming cloned buds that separate from the “parent.” They can also release sperm and eggs into the ocean. Fertilized eggs develop into larva, which float off to start a new colony.”

A new species of crab, called the yeti crab for the bristles covering its arms, was discovered off the coast of Costa Rica. The yeti crab cultivates gardens of bacteria on its claws as its main food source, occasionally waving its arms to stir up the water around the bacteria and therefore ensure its gardens always have fresh supplies of oxygen and sulphide.

This is the source, not my original picture. But this is a Barreleye fish (Macropinna microstoma). His head is transparent and the eyes are inside the transparent part so he can look straight up.

TRIGGER WARNING: SPIDER
I took this photo of a Jewelled spider yesterday. They’re known for their spiked abdomens and come in a variety of colors. They’re a common occurrence in central Florida but are often overlooked because they’re very small!
