O. rastrosus was possibly the largest member of the family Salmonidae, rivalling or exceeding the largest living salmonid Hucho taimen in size, [5] with estimates varying from standard length (without tail fin) of 1.9 m (6 ft 3 in) and 177 kg (390 lb) [1] to total length of 2.4–2.7 m (7 ft 10 in – 8 ft 10 in) and 200 kg (440 lb).
In the wild, alligator snapping turtles are also recorded eating a wide range of plant matter such as seeds, tubers, stalks, American persimmons, wild grape, water hickory, pecans, and locust. Between March and October, stomach samples of 65 turtles showed that 56% of their diet by volume was composed of acorns of water, overcup, and willow ...
The megamouth has a stout body and a long, wide bulbous head. Megamouths are large sharks, able to grow to 5.49 metres (18 ft 0 in) in length. [16] [17] [18] Mature males average at 4 m (13 ft) and females at 5 m (16 ft). Weights of up to 1,215 kg (2,679 lb) have been reported. [19]
The best-preserved specimen of Helicoprion is IMNH 37899 (also known as "Idaho 4"), referred to Helicoprion davisii. It was found in Idaho in 1950 and was originally described in 1966 by Svend Erik Bendix-Almgreen. [8] A 2013 redescription by Tapanila and colleagues was accompanied by CT scanning, to reveal the cartilaginous remains in more ...
Like all sauropods, Nigersaurus was a quadruped with a small head, thick hind legs, and a prominent tail. Among that clade, Nigersaurus was fairly small, with a body length of only 9 m (30 ft) and a femur reaching only 1 m (3 ft 3 in); it may have weighed around 1.9–4 t (2.1–4.4 short tons), comparable to a modern elephant.
In Africa, this catfish has been reported as being second in size only to the vundu of the Zambesian waters, [4] although FishBase suggests the African sharptooth catfish surpasses that species in both maximum length and weight. [5] [6] C. gariepinus has an average adult length of 1–1.5 m (3 ft 3 in – 4 ft 11 in).
The wide mouth is positioned terminally on the head. The jaws contain 10 upper and 9 lower tooth rows on each side, with toothless gaps at the middle. Each tooth has a broad base and a single pointed cusp with smooth edges. There are five pairs of gill slits located on the sides of the head. [4] [5]
