[216] Among living arthropods, the Japanese spider crab (Macrocheira kaempferi) is the largest in overall size, the record specimen, caught in 1921, had an extended arm span of 3.8 m (12 ft) and weighed about 19 kg (42 lb). I write about the planet Earth and science on this website, ourplnt.com. Giant Oarfish (up to 11 meters / 36 feet), 1. Top 6 Biggest Prehistoric Crocodiles A treasure trove of ancient human remains discovered in a cave in South Africa could give us a new picture of human evolution – and evidence of a previously undiscovered species. The constituent zooids form a rigid tube, which may be pale pink, yellowish, or bluish. The Chinese river dolphin, or baiji, holds the unenviable record of being the first dolphin species driven to extinction by human beings. It is strong enough to crush an automobile and even far exceeded that of the Tyrannosaurus rex, which was capable of a maximum bite force of 35,000 to 57,000 newtons at its back teeth. This specimen is still often cited as the largest invertebrate that has ever been examined.

The tentacles of this specimens were as long as 37 m (121 ft) and were projected to have a tentacular spread of about 75 m (246 ft) making it one of the longest extant animals. These great sizes mark the beluga as the largest freshwater fish in the world. The Guinness Book of Animal Facts and Feats.

We are now the only living members of what many zoologists refer to as the human … The largest such colony is Pando, in the Fishlake National Forest in Utah. Fish can be found in nearly all aquatic environments, from high mountain streams (e.g., char and gudgeon) to the abyssal and even hadal depths of the deepest oceans (e.g., gulpers and anglerfish); in environments as hot as 104°F/40°C and as cold as 28°F/-2°C. [275] Pando, a clonal colony of the quaking aspen tree, is widely considered to be the largest such organism by mass. However, it is nearly impossible to differentiate the adult male from the female using external anatomy alone. One giant squid specimen that washed ashore in 1878 in Newfoundland reportedly measured 18 m (59 ft) in total length (from the tip of the mantle to the end of the long tentacles), head and body length 6.1 m (20 ft), 4.6 m (15 ft) in diameter at the thickest part of mantle, and weighed about 900 kg (2,000 lb).
