Seahorse is the name given to 54 species of small marine fishes in the genus Hippocampus. "Hippocampus" comes from the Ancient Greek word hippos meaning "horse" and kampos meaning "sea monster". Having a head and neck suggestive of a horse, seahorses also feature segmented bony armor, an upright posture and a curled prehensile tail. Seahorses, along with pipefish, belong to the family Synathidae. Common features include elongated bodies, protruding bony rings and a skinny tubular snout tipped with a tiny toothless mouth; seahorses feed primarily on plankton and tiny benthic animals.
The male of the species caries the babies and delivers them. The dorsal fin on the seahorse's back is its most powerful means of propulsion; fluttering up to 70 times per second. A pair of pectoral fins behind the seahorse's head help with steering and braking. Because of their inability to move quickly, seahorses live a relatively stationary existence, typically inhabiting regions of the reef where there is little or no current.
They are often territorial and stay in the same location making it easy for a dive master to remember where one was last seen.
They do not spook easily so if you are fortunate enough to find one they are relatively easy to photograph.
Good luck hunting.

Sea bunny, named Jorunna parva, lives in the waters of the Indo-Pacific Ocean. That white fur coat you see on the sea bunny slug is usually yellow or orange. What looks like fur are groups of small rods known as caryophyllidia, which cover its back. The two ears that make the creatures look like bunnies are rhinophores, and they help them to identify chemicals in the water that allow them to find food and mates
Sharks mature slowly, and reach reproductive age anywhere from 12 to 15 years. This, combined with the fact that many species only give birth to one or two pups at a time, means that sharks have great difficulty recovering after their populations have declined.
Soon after birth, sharks pups swim away to fend for themselves. They are born with fully-fledged sets of teeth and are able to feed and live on their own.
The adult queen angelfish overall body color can be described as blue to blue green with yellow rims on its scales. Their pectoral and ventral fins are also yellow but their lips and the edges of their dorsal fins and anal fins are dark blue. Queen angelfish are also known to have blue markings around each gill cover. The queen angelfish may live up to 15 years in the wild and reach up to 17 inches in length.
The queen angelfish feeds primarily on sponges, but also feeds on tunicates, jellyfish, and corals as well as plankton and algae. Queen angelfish inhabit reefs and are common in Florida, the Florida Keys, the Bahamas, the gulf of Mexico and range as far south as Brazil.
Juveniles have dark blue bodies with yellow lips, gills, and tail and vertical bars ranging in color from light blue to white. The colors of the juvenile fish help them to blend in with the reefs. Juveniles serve as "cleaners" and feed on the parasites of larger fish at cleaning stations.

A plasticus Iioness is a plastic toy from Petco.
Size: The spined pygmy shark, a deep-sea shark, is one of the smallest at only about 7-8 inches, while the whale shark is the largest shark, and fish, at about 50 feet in length. Although lifespan varies by shark species, most sharks are long-lived and generally tend to live for 20-30 years. Species like the spiny dogfish and the whale shark are believed to live for over 100 years!
Yellow Fin Grouper
The body is greenish-olive or bright red. Oval groups of dark spots form horizontal rows on the body. Outer third of pectoral fins are bright yellow. Small bright red spots are found on lower parts of large individuals.They commonly grow to 20 lbs. Live in coastal reef shallows to modestly deep offshore waters. Juveniles found in mangroves and sea grass beds. Feeds on fishes and squid. Can often be seen at cleaning stations.
The yellowfin grouper is a hearty fish, often reaching 10 kg. It is considered quite tasty and is one of the more popular Gulf game fishes. This species is one of the main catches in the fishing industry in Bermuda. It is considered over fished, and is currently threatened in several areas.

Answer: Real - Bioluminescent Dinoflagellate Plankton
In 1753, the first modern dinoflagellates were described by Henry Baker as "Animalcules which cause the Sparkling Light in Sea Water". Sometimes referred to as "Fire Algae" it is recognized usually in darkness as it has the appearance of blue glowing glitter swirling in the water when disturbed. Truly a wonder of nature. This particular Dinoflagellate looks earily like an alien spacecraft. Photo by Joe Scott
The oriental sweetlips (Plectorhinchus vittatus), is a species of grunt. Closely related to the snappers, grunts have smaller mouths and teeth and thicker fleshy lips hence the name sweetlips.
They may also grind their teeth together when caught, emitting a grunting sound, hence the name grunt.
Juvenile oriental sweetlips have an attractive brown-and-white and yellow mottled pattern. They have a curious wriggling style of swimming in which the whole body undulates, which does not completely disappear in the adults.
They can be found in found in fresh, brackish, and salt waters and tend to be in medium to large schools. Divers often are able to approach slowly and get very close as they are not very skiddish.

One simple thing you can do to help
Buoyancy Control is a little bit science and a whole lot of practice. Here are a few tips to help you master the skill. We have monthly classes on Buoyancy.
Note: So many factors affect your buoyancy that are impossible to control. So we do the best we can. Example would be the buoyancy of your suit. At 10 feet deep it is different than at 20 feet. Air in your BCD (even if you think it is empty) changes volume and lift every foot you descend. How deeply you inhale, the layers you have worn, the temperature of the water, the size tank and how full it is or isn't.
Try this in a pool. Adjust your weights to as little as you can and still stay on the bottom. The fin pivot is when your fin tips are touching the bottom and you rise from flat on your belly to about a 45 degree angle just by inhaling. When you exhale you sink back to your belly all the while your fin tips never leave the bottom. Then practice rising and falling under control using only your breathing. Try holding still.
Now, after mastering the fin pivot, try the hover. Cross your legs, grabbing your left fin with your right hand and your right fin with your left hand. Inhale just enough to rise off the bottom. Control your breathing to try and stay in one place off the bottom.
With another diver with you in the pool, practice the hover and pass a weight between you. So, you are hovering just fine and you are handed a 3 lb weight. You adjust by inhaling more deeply to become just buoyant enough to offset the 3 lbs. When you regain your control then you hand it back. Then 4 lbs, then 5 lbs.
Have fun learning.
