Yet at least one example shows a fisher kept in captivity that lived to be 10 years old, and another living to be about 14 years old, [76] well beyond its natural lifespan of 7 years. [ 77 ] [ 78 ] In 1974, R.A. Powell raised two fisher kits for the purpose of performing scientific research.
The Sumatran tiger is one of the smallest tigers. Males measure between the pegs 2.2 to 2.55 m (7 ft 3 in to 8 ft 4 in) in head-to-body length, with the greatest skull length of 295 to 335 mm (11.6 to 13.2 in) and weigh 100 to 140 kg (220 to 310 lb).
Comparison of multiple size estimates for D. terrelli. Dunkleosteus was covered in dermal bone forming armor plates across its skull and front half of its trunk. This armor is often described as being over 2–3 inches (5.1–7.6 cm) thick, [26] [14] but this is only across the thickened nuchal plate at the back of the skull. [14]
A fisher, a mammal related to river otters and weasels, found as roadkill in Ashtabula County in 2023, was recently confirmed to be pregnant, according to the Ohio Department of Natural Resources ...
Researchers unearthed the skull of a previously unknown starling-sized bird species named Navaornis hestiae that was so well preserved they were able to digitally reconstruct its brain and inner ...
The biggest odobenid and one of the biggest pinnipeds to have ever existed is Pontolis magnus, with a skull length of 60 cm (24 in) (twice as large as the skulls of modern male walruses) [153] and having a total body length of more than 4 m (13 ft). [154] [155] Only the modern male elephant seals reach similar sizes. [154]
Its skull is massive, measuring 53 cm (1 ft 9 in) in length. [1] For comparison, in a 2007 study, a sample of 110 beef cows belonging to 9 different breeds had a maximum head length of 52.8 cm (1 ft 9 in). [13] Its skull is 65% bigger than the skull size of the previous largest identified rodent, Phoberomys pattersoni. [14]
[7] [9] A 2024 study found that all anglerfish suborders most likely diverged from one another during the Late Cretaceous and Paleocene, but the multiple families of deep-sea anglerfishes (Ceratioidei), as well as their trademark sexual parasitism, originated during the Eocene in a rapid radiation following the Paleocene-Eocene thermal maximum.
