A cephalopod is any member of the molluscan class Cephalopoda (Greek plural Κεφαλόποδα (kephalópoda); "head-feet"). These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishermen sometimes call them inkfish, referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by Nautilus and Allonautilus. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been identified. Two important extinct taxa are the Ammonoidea (ammonites) and Belemnoidea (belemnites). Let me take a shot in the dark. You're more interested in the non-cephalopod creature featured in the photo.
Australian Pineapplefish:(Scientific name: Cleidopus gloriamaris. Family: Monocentrididae.) Found in caves and under ledges of rocky, occasionally coral-reef habitats. Max length of about 22cm. Found in depths from 6m to 200m.
Not just a hazard to your score, but to your life. Mommy! A half dozen Bull sharks got stranded in a small lake after a flood near Brisbane, Australia. It's said that they are fond of golf balls, birds and small mammals. The sharks are often seen trying to tempt the golf club members into the water, something about the joy of swimming.
The Bull shark, Carcharhinus leucas, also known as Zambezi shark or unofficially known as Zambi in Africa and Nicaragua shark in Nicaragua, is a shark common worldwide in warm, shallow waters along coasts and in rivers. The bull shark is well known for its unpredictable, often aggressive behavior.
The Bull shark is most famous for its remarkable ability to thrive in both saltwater and freshwater and can travel far up rivers. They have even been known to travel as far up as Indiana in the Ohio River and Illinois in the Mississippi River, although there have been few recorded attacks. As a result, they are probably responsible for the majority of near-shore shark attacks, including many attacks attributed to other species.
