Parrotfish are named for their dentition, [5] which is distinct from other fish, including other labrids.Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot-like beak with which they rasp algae from coral and other rocky substrates [6] (which contributes to the process of bioerosion).
The gray whale (Eschrichtius robustus), [1] also known as the grey whale, [5] is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of 14.9 meters (49 ft), a weight of up to 41 tonnes (90,000 lb) and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age.
Blue whales eat almost 9,000 pounds of krill daily, and when it's their feeding season, they eat up to 40 million krill a day. Treehugger also shared this cool fact, "Blue whales, in fact, are the ...
But National Geographic says, "Sperm whales are known to dive as deep as 3,280 feet in search of squid to eat. These giant mammals must hold their breath for up to 90 minutes on such dives."
Whales are fully aquatic, open-ocean animals: they can feed, mate, give birth, suckle and raise their young at sea. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the
The nutrient rich waters that provide this feeding ground for the whales often do not have good visibility. The only indication of a bubble net occurring that can be sighted on the surface is a ring of bubbles coming up. It is also common to see birds flock to the area where the whales will feed hoping to catch the fish being brought to the ...
