This week brought baby gorilla siblings together, death to the well-known Marsh lions in Kenya, new ways to combat shark attacks in Australia and more.

ZSL London Zoo has a new baby gorilla and has released video of the tiny primate's first meeting with its half-sibling.
Dan Simmonds, a gorilla keeper at the zoo, said in the video that the zoo is thrilled about the new male, which has been named Gernot. The new baby is the half-sibling of another infant born a year ago, a female named Alika.

He said the baby has brought the troop together and is good social enrichment for the gorillas, and while Alika was a bit jealous at first, she is now fascinated by her little half-brother. Plus, having the new baby around is helping Alika mature more quickly, according to Simmonds.
“Alika is incredibly excited.”
