Some scientists have been experimenting on the intelligence of the octopus. They've been able to control the octopus's tentacles, open jar lids, and even board fishing boats. The moray eel, which is the biggest threat to the octopus, is also able to sever its tentacles in just one bite. The ink that the ink contains is made of melanin, which can be harmful to humans, but it can also be useful for writing.
