An iceberg in the Arctic Ocean. An iceberg is a piece of fresh water ice more than 15 meters (16 yards) long [1] that has broken off a glacier or an ice shelf and is floating freely in open water. [2] [3] Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits".
Sea lion attacks on humans are rare, but when humans come within approximately 2.5 meters (8 ft), it can be very unsafe. [26] In a highly unusual attack in 2007 in Western Australia, a sea lion leapt from the water and seriously mauled a 13-year-old girl surfing behind a speedboat. The sea lion appeared to be preparing for a second attack when ...
A sea-lion, illustrated in A Complete Guide to Heraldry (1909). In heraldry, the term sea-lion (sometimes called a morse) [1] refers to a legendary creature that has the head and upper body of a lion, but with webbed forelimbs and a fish tail. [2] These occur most frequently as supporters, but also occur as crests and occasionally as charges. [1]
Hauling out is a behaviour associated with pinnipeds (true seals, sea lions, fur seals and walruses) temporarily leaving the water. [1] [2] Hauling-out typically occurs between periods of foraging activity. [1] [3] [4] Rather than remain in the water, pinnipeds haul out onto land or sea ice for reasons such as reproduction and rest.
Ice rafting is the transport of various materials by floating ice. [1] Various objects deposited on ice may eventually become embedded in the ice. When the ice melts after a certain amount of drifting, these objects are deposited onto the bottom of the water body , e.g., onto a river bed or an ocean floor .
The 3-minute-long video shows a sea lion thrashing about with an octopus. The sea lion flings the octopus forcefully away, then dives underwater and repeats the movement.
The Australian sea lion (Neophoca cinerea), also known as the Australian sea-lion or Australian sealion, is a species of sea lion that is the only endemic pinniped in Australia. [2] It is currently monotypic in the genus Neophoca , with the extinct Pleistocene New Zealand sea lion Neophoca palatina the only known congener. [ 3 ]
Many free-swimming sea slugs, such as sea angels, flap fin-like structures. Some shelled molluscs, such as scallops can briefly swim by clapping their two shells open and closed. The molluscs most evolved for swimming are the cephalopods. Violet sea-snails exploit a buoyant foam raft stabilized by amphiphilic mucins to float at the sea surface ...
