the weird fish under the blue ocean.
The Pinecone Fish also called the Pineapple Fish and Knight-fish is a small and unusual beryciform marine fish member of the family Monocentridae, of the Order Beryciformes, Class Actinopterygii. It is an unusual armored fish of the Indo-Pacific whose body has a vaguely pinecone pattern made by the joining of hard scutes, which provide protection to the fish from her enemies. There are four species of pinecone fish which are Monocentris japonica, Monocentris meozelanicus, Monocentris reedi, and Cleidopus gloriamaris.

It is 8-15 cm long (3-6 in), and is covered with spines, and has a brilliant yellow body somewhere it can be yellow to orange in color. It has what appears to be a glowing smile due to the bioluminescent bacteria which inhabit the light organs found on the sides of the mouth. All pinecone fish have phosphorescent organs at either side of the lower jaw that can turn off and on by movement of the jaw. It has a large, blunt head, and interestingly, its dorsal fin is not situated on the center of its back like that of most fish, but is off-center and the second dorsal and anal fins are at the rear of the animal, pointing backward.

This fish generally seeks shelter by day in caves, crevices and under overhangs. It lives in tropical and sub-tropical waters. The pinecone fish is popular in tropical aquariums due to its unusual appearance, but it is considered a difficult fish to keep.

Origin from Australia, Coral Sea but their distribution is limited to tropical and subtropical waters of the Indo-Pacific.

At the maturity, the largest scientifically measured Naso tang was 46.0 cm /18 in. At the time of juvenile, the body is of a grayish brown shade and a prominent yellow line runs from the back of the mouth up to the eye. At maturity, the body takes on a darker bluish-gray tone and the juvenile striping is supplemented with additional color. The tail takes on a lyre shape and two yellow patches appear at the peduncle spines near the tail. A thin, black mask forms between the eyes and mouth, and the lips develop a yellow color.

It is found among corals, rocks and rubble in lagoons and seaward reefs. The depth range for this amazingly beautiful sea species is about 0-90 meters / 0-295 feet. Juveniles prefer shallow rocky reefs and will sometimes form small aggregations together with other similarly sized members of the family Ancanthurus but the adults typically live in small groups and sometimes large aggregations also occur.  

Origin is from Maldives but the Naso lituratus is also found in the western and central Pacific Ocean, from Honshu in Japan to New Caledonia and Australia's Great Barrier Reef. Eastwards, its range proceeds to Hawaii, French Polynesia, and Pitcairn.

Mantis shrimp – a colorful and fascinating sea creature.

a colorful and fascinating sea creature.
Mantis shrimp or stomatopods are marine crustaceans and it is the members of the order Stomatopoda. The shrimp is a fascinating creature that has the ability to punch its prey into submission with a club that accelerates underwater at around 10,400 g. It is called "sea locusts" by ancient Assyrians, "prawn killers" in Australia and now it also referred as "thumb splitters" because of the animal's ability to inflict painful gashes if handled incautiously.

They may reach nearly 30 centimeters in length but in exceptional cases it has been recorded up to 38 centimeters. The carapace of mantis shrimp covers only the rear part of the head and the first four segments of the thorax. Mantis shrimp appear in a variety of colors, from shades of browns to bright neon colors. Mantis Shrimp are crustaceans that live in shallow waters and normally grow to about a foot long. More then 400 species of mantis shrimp have currently been described worldwide. They are commonly separated into two distinct groups (Spearers and Smashers) determined by the manner of claws.

The mantis shrimp has very powerful claws that they use to attack and kill prey by spearing, stunning, or dismemberment. Although it happens rarely, some larger species of mantis shrimp are capable of breaking through aquarium glass with a single strike from this weapon. The mantis shrimp uses its formidable weapon to break the shells of its prey but, until recently, it was unclear how its club could receive such a severe, repetitive pounding without suffering too much damage. The club, in fact, handles as many as fifty thousands strikes during its lifespan.

Blue - ringed octopus - the deadliest creatures under the blue ocean.

Residing in the Pacific Ocean anywhere from Japan to Australia, the blue-ringed octopus is a tiny and beautiful sea creature which is feeds off of small crabs, shrimp and wounded fish.

Described by British zoologist Guy Coburn Robson in 1929, the blue-ringed octopuses (genus Hapalochlaena) are three or four octopus species that live in tide pools and coral reefs. At the size of a golf ball and having a yellowish/brown coloring, they are recognized as some of the world's most venomous marine animals.

Although small in size, it is easily able to camouflage itself into its surroundings and it has powerful enough venom to kill humans with just one bite and most attacks on humans occur only when the octopus has been picked out of its pool or stepped on. With no known antidote, this makes it the most toxic known sea creature. They can be recognized by their characteristic blue and black rings and yellowish skin. Normally, 50-60 blue rings cover the dorsal and lateral surfaces of the mantle.

Pterois, commonly known as lionfish, is a genus of venomous marine. It is characterized by red, white and black bands, showy pectoral fins and venomous spiky fin rays. The lionfish is one of the most venomous fish on the ocean floor. Lionfish have venomous dorsal spines that are used purely for defense. When threatened, the fish often faces its attacker in an upside down posture which brings its spines to bear.

Lionfish, also called turkey fish, dragon fish and scorpion fish, are native to the reefs and rocky crevices of the Indo-Pacific, although they've found their way to warm ocean habitats worldwide. Average life span in the wild of a Lionfish is up to 15 years and size 11.8 to 15 in (30 to 38 cm). It’s maximum weight up to 2.6 lbs (1.2 kg). A lionfish will often spread its feathery pectoral fins and herd small fish into a confined space where it can more easily swallow them.

However, a lionfish’s sting is usually not fatal to humans but a sting from a lionfish is extremely painful to humans and can cause nausea and breathing difficulties. Lionfish are popular in some parts of the world as Sea food, but are far more prized in the aquarium trade.

The Lionfish are widely distributed throughout the western Pacific from southern Japan to MicronesiaAustralia and the Philippines. Lionfish is volitions occur throughout most of Oceania (including the Marshall IslandsNew Caledonia and Fiji) east to French Polynesia.

The Moorish idol (Zanclus cornutus "Crowned Scythe" Linnaeus, 1758) is the only extant member of the family Zanclidae (order Perciformes). The Moorish idol got its name from the Moors of Africa, who purportedly believe the fish to be a bringer of happiness. One of the most beautiful sea fish - Moorish idol is a small marine fish species. Some authors and scientist place it in the family Acanthuridae (the surgeonfishes), though it differs from members of this group conspicuously in its lack of peduncular spines. It has also been placed (much more erroneously) in the family Chaetodontidae (the butterflyfishes).

The Moorish idol is a saltwater fish coming from the Indian Ocean or Pacific Ocean. A common inhabitant of tropical to subtropical reefs and lagoons, the Moorish idol is notable for its wide distribution throughout the Indo-Pacific. A number of butterfly fishes (genus Heniochus) closely resemble the Moorish idol. It is closely related to, if not a direct descendant of the extinct Eozanclus brevirhostris, from the Middle Eocene of Monte Bolca.

One of the most difficult fish to keep in a home aquarium (and very expensive as well), to most aquarists these fish are the pinnacle of the hobby. Moorish idols are also popular aquarium fish, but despite their popularity, they are notorious for short aquarium lifespan and sensitivity.

Often seen alone, Moorish idols also form pairs or occasionally small schools, especially as juveniles. They are diurnal fish, sticking to the bottom of the reef at night, adopting a drab coloration.
