The exact lifestyle of Dimetrodon (amphibious to terrestrial) has long been controversial, but bone microanatomy supports a terrestrial lifestyle, [82] which implies that it would have fed mostly on land, on the banks, or in very shallow water. Evidence also exists for Dimetrodon preying on aestivating Diplocaulus during times of drought, with ...
'to swim') is any aquatic organism that can actively and persistently propel itself through a water column (i.e. swimming) without touching the bottom. Nektons generally have powerful tails and appendages (e.g. fins , pleopods , flippers or jet propulsion ) that make them strong enough swimmers to counter ocean currents , and have mechanisms ...
There are also aquatic spiders, although they tend to prefer other modes of locomotion under water than swimming proper. Examples are: Some breeds of dog swim recreationally. Umbra, a world record-holding dog, can swim 4 miles (6.4 km) in 73 minutes, placing her in the top 25% in human long-distance swimming competitions. [35]
The teeth of Dimetrodon borealis are long, recurved, and distinctively teardrop-shaped, being widest at the middle rather than the base. The teardrop shape of the teeth is an indication that Dimetrodon borealis belongs to the family Sphenacodontidae.

The latter group swim slowly, but can turn rapidly, as is needed when living in coral reefs for example. But they can not swim as fast as fish using their bodies and caudal fins. [1] [2] Skeletal anatomy of Tilapia [3] Consider the tilapia shown in the diagram. Like most fish, the tilapia has a streamlined body shape reducing water resistance ...
