Heptranchias is a genus of sharks in the family Hexanchidae.
Fossils of Heptranchias are found in marine strata from the Cretaceous period. Fossils are known from various localities in Europe, North America, South America, New Zealand and Japan. [3]
The zitting cisticola or streaked fantail warbler is a widely distributed Old World warbler whose breeding range includes southern Europe, Africa, and southern Asia down to northern Australia. A small bird found mainly in grasslands, it is best identified by its rufous rump; in addition it lacks any gold on the collar and the brownish tail is tipped with white. During the breeding season males have a zigzagging flight display accompanied by regular "zitting" calls that have been likened to repeated snips of a scissor. They build their pouch nest suspended within a clump of grass.

Abbé Pierre Joseph Bonnaterre was a French zoologist who contributed sections on cetaceans, mammals, birds, reptiles, amphibians, fish, and insects to the Tableau encyclopédique et méthodique. He is also notable as the first scientist to study the feral child Victor of Aveyron.
The Tableau encyclopédique et méthodique des trois regnes de la nature was an illustrated encyclopedia of plants, animals and minerals, notable for including the first scientific descriptions of many species, and for its attractive engravings. It was published in Paris by Charles Joseph Panckoucke, from 1788 on. Although its several volumes can be considered a part of the greater Encyclopédie méthodique, they were titled and issued separately.
The bramble shark is one of the two species of sharks in the family Echinorhinidae. Aside from the eastern Pacific Ocean, it is found in tropical and temperate waters worldwide. This rarely encountered shark swims close to the bottom of the seafloor, typically at depths of 400–900 m (1,300–3,000 ft), though it may enter much shallower water. The bramble shark has a stout body with two small dorsal fins positioned far back and no anal fin. It can be readily identified by the large, thorn-like dermal denticles scattered over its body, some of which may be fused together. It is purplish brown or black in color and grows up to 3.1 m (10 ft) long.
The kitefin shark or seal shark is a species of squaliform shark in the family Dalatiidae, and the type species in its genus. It is found sporadically around the world, usually close to the sea floor at depths of 200–600 m (660–1,970 ft). With a sizable oil-filled liver to maintain neutral buoyancy, this shark is able to cruise slowly through the water while expending little energy. The kitefin shark, the largest luminous vertebrate on record, has a slender body with a very short, blunt snout, large eyes, and thick lips. Its teeth are highly differentiated between the upper and lower jaws, with the upper teeth small and narrow and the lower teeth large, triangular, and serrated. Its typical length is 1.0–1.4 m (3.3–4.6 ft), though examples as long as 5.9 ft (180 cm) have been encountered.
Galeus is a genus of catshark, belonging to the family Scyliorhinidae, commonly known as sawtail catsharks in reference to a distinctive saw-toothed crest of enlarged dermal denticles, found along the upper edges of their caudal fins. They are found in the Atlantic, the western and central Pacific, and the Gulf of California, inhabiting deep waters at or close to the sea floor. Members of this genus are rather small, slim sharks with firm bodies and thick, rough skin. Their heads are usually fairly long and pointed, and have large mouths with well-developed furrows at the corners. They have large pectoral and anal fins, and two similar dorsal fins placed well back. Many species are ornately patterned with dark saddles and/or blotches. Sawtail catsharks feed on various invertebrates and fishes, and may be either egg-laying or live-bearing. These harmless sharks are sometimes caught as bycatch but are of minimal commercial value.
The blackmouth catshark is a species of catshark, and part of the family Scyliorhinidae, common in the northeastern Atlantic Ocean from Iceland to Senegal, including the Mediterranean Sea. It is typically found over the continental slope at depths of 150–1,400 m (490–4,590 ft), on or near muddy bottoms. The youngest sharks generally inhabit shallower water than the older juveniles and adults. This slim-bodied species is characterized by the black interior of its mouth, a marbled pattern of pale-edged brownish saddles or blotches along its back and tail, and a prominent saw-toothed crest of enlarged dermal denticles along the upper edge of its caudal fin. It reaches lengths of 50–79 cm (20–31 in), with sharks in the Atlantic growing larger than those in the Mediterranean.

The rufus snake eel is an eel in the family Ophichthidae. It was described by Constantine Samuel Rafinesque in 1810, originally under the genus Echelus. It is a marine, subtropical eel which is known from throughout the Mediterranean and the Black Sea, in the northeastern Atlantic Ocean, including Algeria, Albania, Croatia, Egypt, France, Cyprus, Gibraltar, Greece, Italy, Israel, Montenegro, Lebanon, Libya, Malta, Morocco, Monaco, Slovenia, Spain, Tunisia, the Syrian Arab Republic, and Turkey. It inhabits mud sediments on the continental shelf. Males can reach a maximum total length of 60 centimetres (24 in).
