Southern Right Whale (by runner_ay)
Olympia has a white lanugo coat, an indication that she was born prematurely. Tim Lebling, ASLC Stranding Coordinator, stated, “It is likely that Olympia was abandoned by her mother, as we commonly find that seals abandon their premature pups.” Olympia is currently in “good but guarded” condition, and will be cared for until she can be released back into the wild. She ASLC’s first stranded Seal in 2012. (via zooborns)
Tongue Eating Louse (Cymothoa exigua)
A pair of ocellaris clownfish (Amphiprion ocellaris) are hosts to the tongue eating louse. The parasite enters the fish through its gills where they extract blood from the tongue. It then replaces the atrophied tongue, attaching its own body to the stub. The fish is able to use the parasite just like a normal tongue. This is the only known case of a parasite functionally replacing a host organ.
