Off the coast of Australia Macroctopus caught the shark, wrapped all its tentacles around it and soon released it. Most likely, he scraped all the parasites off her.
Cuttlefish can change color to fade into the background. It can do it amazingly fast.

The mahi-mahi or common dolphinfish (Coryphaena hippurus) is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. It is also widely called dorado (not to be confused with Salminus brasiliensis, a freshwater fish) and dolphin (not to be confused with the aquatic mammal dolphin). It is one of two members of the family Coryphaenidae, the other being the pompano dolphinfish. These fish are most commonly found in the waters around the Gulf of Mexico, Costa Rica, Hawaii and the Indian Ocean.
The name mahi-mahi comes from the Hawaiian language and means 'very strong', through the process of reduplication. By chance in Persian, mahi (ماهی) means 'fish', but the word mahi-mahi is Hawaiian. Though the species is also referred to as the common dolphinfish, the use of dolphin can be misleading as they are not closely related to dolphins; see Coryphaena for the possible etymologies of dolphinfish. In parts of the Pacific and along the English-speaking coast of South Africa, the mahi-mahi is commonly referred to by its name in Spanish, dorado. On the Mediterranean island of Malta, the mahi-mahi is referred to as the lampuka. In Indonesian, they are called ikan lemadang.
Linnaeus named the genus, derived from the Greek word, κορυφή, koryphe, meaning 'top' or 'apex', in 1758. Synonyms for the species include Coryphaena argyrurus, Coryphaena chrysurus, and Coryphaena dolfyn.
Mahi-mahi have compressed bodies and one very long dorsal fin extending from the head almost to the tail fin. Mature males have distinctive "foreheads"; it grows as the fish matures and often protrudes well above the body proper, which is streamlined by the musculature of the back. This "hump" is a sexually dimorphic feature; females have a rounded head. Their caudal fins and anal fins are sharply concave. They are distinguished by dazzling colors – golden on the sides, and bright blues and greens on the sides and back. The pectoral fins of the mahi-mahi are iridescent blue. The flank is broad and golden. Out of the water, the fish often change color (giving rise to their Spanish name, dorado, 'golden'), going through several hues before finally fading to a muted yellow-grey upon death.
Mahi-mahi can live for up to five years, although they seldom exceed four. Females are usually smaller than males. Catches typically are 7 to 13 kg (15 to 29 lb) and a meter in length. They rarely exceed 15 kg (33 lb), and mahi-mahi over 18 kg (40 lb) are exceptional. Mahi-mahi are among the fastest-growing of fish. They spawn in warm ocean currents throughout much of the year, and their young are commonly found in rafts of Sargassum weeds. Young mahi-mahi migrate past Malta where they are called lampuki and Sicily where they are known as lampuga or capone; there they are fished using nets and floating mats of palm leaves under which they collect.
Mahi-mahi are carnivorous, feeding on flying fish, crabs, squid, mackerel, and other forage fish. They have also been known to eat zooplankton. To pursue such varied pelagic prey, mahi-mahi are fast swimmers, swimming as fast as 50 knots (92.6 km/h, 57.5 mph).[citation needed]
Males and females are sexually mature in their first year, usually by the age of 4–5 months. Spawning can occur at body lengths of 20 cm (7.9 in). Females may spawn two to three times per year, and produce between 80,000 and 1,000,000 eggs per event. In waters at 28 °C/83 °F, mahi-mahi larvae are found year-round, with greater numbers detected in spring and fall. Mahi-mahi fish are mostly found in the surface water. Their flesh is grey-white when raw, cooking to an attractive white with a clean, non-fishy flavour.

NEW HAMMERHEAD SHARK JUST DROPPED
Not every day does a new shark get discovered! Meet the Shovelbill Shark (Sphyrna alleni), a newly described species of hammerhead shark named after Microsoft co-founder and philanthropist Paul Allen. This new species is found in the coastal waters of the Caribbean and southwest Atlantic.
Hammerhead sharks are easily recognized by their laterally expanded and dorsoventrally compressed heads. Genetic studies have revealed that what was once thought to be a single bonnethead species (Sphyrna tiburo) is actually a complex, with Sphyrna alleni now recognized as a separate species. A longtime advocate for wildlife conservation, Paul Allen and his Paul G. Allen Family Foundation supported Global FinPrint, an international survey of the world’s reef sharks and rays. It was during this project that scientists conducted much of the fieldwork necessary to describe this newly recognized species. The Shovelbill Shark is smaller than the bonnethead, with distinct genetic and morphological characteristics, including a different number of vertebrae, which suggest it is separate from other hammerhead species. This new species is distributed from Belize to Southern Brazil, inhabiting estuaries, coral reefs, sandy and muddy bottom beds, seagrasses, and mangroves.
The Shovelbill Shark is a common component of artisanal fisheries in many Latin American countries and currently lacks proper management or protection. Previous reports indicate that this new species is undergoing overexploitation, making it imperative to safeguard their populations and establish fisheries regulations.

very small rainbow darter fishes!! so breathtaking!!
everyone say thank you for sharing Bob Krysiak on Pinterest
Chitons formerly known as Amphineura. About 940 extant and 430 fossil species are recognized.
They are also sometimes known as sea cradles or coat-of-mail shells or suck-rocks, or more formally as loricates, polyplacophorans, and occasionally as polyplacophores.
Chitons have a shell composed of eight separate shell plates or valves. These plates overlap slightly at the front and back edges, and yet articulate well with one another. Because of this, the shell provides protection at the same time as permitting the chiton to flex upward when needed for locomotion over uneven surfaces, and even allows the animal to curl up into a ball when dislodged from rocks. The shell plates are encircled by a skirt known as a girdle.
Chitons live worldwide, from cold waters through to the tropics. They live on hard surfaces, such as on or under rocks, or in rock crevices.
Some species live quite high in the intertidal zone and are exposed to the air and light for long periods. Most species inhabit intertidal or subtidal zones, and do not extend beyond the photic zone, but a few species live in deep water, as deep as 6,000 m (20,000 ft).
Chitons are exclusively and fully marine, in contrast to the bivalves, which were able to adapt to brackish water and fresh water, and the gastropods which were able to make successful transitions to freshwater and terrestrial environments.
that eclipse the other night was spectacular huh
ok but seriously. it was pretty cool to see
