The test may be repeated to see if the abnormal result persists. Chronic kidney disease is diagnosed when a person has an eGFR less than 60 mL/min/1.73m2 for more than three months. A person may have some kidney damage even with an eGFR greater than 90 mL/min/1.73m2.
Giant squid can snatch prey up to 33 feet (10 meters) away by shooting out their two feeding tentacles, which are tipped with hundreds of powerful sharp-toothed suckers. These feeding tentacles are very long, often doubling the total length of the giant squid on their own.
There are suckers on both the arms and tentacles of the colossal squid. All squid have suckers and their number, type, and arrangement is unique for each species. Squid suckers have a calcareous inner structure. In colossal squid these are sharply serrated and probably lethal to prey.
