About Sea Lobsters

Sea lobsters are invertebrates; they are the members of Crustacea of the Phylum Arthropoda. In this class you can find sea animals without backbones and having hard shells like crab, shrimp, crayfish etc. Male lobster is usually called cock and a female lobster as hen or chicken.

Physical characteristics:
Sea lobsters are ten-legged creature and are closely related to shrimp and crabs. These bottom-dwelling, creatures are found all over the world’s oceans, brackish environments and even in freshwater. Their eyesight is poor but they have highly developed senses of taste and smell. They feed on fish and mollusks, but they also consume algae and other plant life and even other lobsters. Lobster blood is a clear liquid substance. When you start boiling lobsters, the blood turns to a non-transparent whitish gel. It has no flavor and is perfectly safe to consume.

Sea lobsters are of different colors. Usually they are blue-green, including, yellow, red, or white. You can even see them in two different colors, having half of their shell one color and the other half has different color. Out of all these only the white color sea lobsters known as true albinos do not turn red when they are cooked.

Sea lobsters feed on crabs, star fish, or sea urchins. They are not cannibal, but when they are held in traps…??. Even with claws, it's not unusual to find eaten animals in the live-tank when you make it empty.

About Mollusks

The mollusks or molluscs according to American spelling and British spelling respectively are the second largest phylum, Mollusca of invertebrates after Arthropods. The molluscs are well-known for their decorative shells or as seafood. These mollusks consist of octopus, clams, snails, abalone, cuttlefish, and squid. The 50,000 species of mollusks are known to the human being.
In more simple words it can be said that a mollusk is another name for a shellfish. There are three groupings of shellfish. They are as follows:

Hatchet-footed - These live inside the two shells that are joined by a muscular hinge, which can close and open the shell. These are called as bivalves. The age of the mollusks is known by its lines on the shell. As the shell gets bigger, the shellfish gets older. Some of the examples of bivalves are clams, scallops, mussels and oysters.
Belly-footed - These species has just one spiral shell. They carry their shells on their backs and are called univalves. Some of the examples of this group are the snail, slug, conch and periwinkle.
Head-footed – These species are known as head-footed as they have a definite head surrounded by tentacles. The two of the species in this group are squid and octopus

Differences between phytoplankton and zooplankton

Basic difference: Phytoplanktons are aquatic plants and produce energy. They have the capability to covert solar energy into chemical energy. While zooplanktons are sea animals and they feed on phytoplankton. Diatoms and algae are two types of phytoplankton that are commonly found. Small fish or crustaceans are examples of zooplankton.

Difference in food habits: As phytoplankton is a plant, it is natural that they make their own food by the process of photosynthesis. On the other hand, zooplankton depends on the phytoplankton and other particulate that is found in the seawater for food. Phytoplankton is the primary source of food for the zooplankton.

Oxygen: Phytoplankton releases a lot of oxygen into the atmosphere through the process of photosynthesis as they are plants. However, zooplankton cannot produce oxygen like phytoplankton.

Sea Dragons are the most magnificent and extraordinary of all ocean fish.

Sea dragons are like seahorses, they are a type of pipe fish. Sea dragons are found in Australian waters and belong to the same family as sea horses but differ in 3 main ways - Looks, they have "appendages" from their body which look like ether weeds or leafs
Sea Dragons are arguably the most magnificent and extraordinary of all ocean fish. The sea dragon’s body is hard, almost like armor. Sea dragons like to eat tiny shrimps known as 'sea-lice', plankton and small deep sea fish. They don't have any teeth so they eat by taking in small amounts of water containing their prey.

There are two types of sea dragons Australian waters:
• Leafy Sea dragon
• Weedy Sea dragon

Leafy sea dragon

The leafy sea dragon is also called as Glauerts Sea dragon. Which belong with family Syngnathidae. It is found along the southern and western coasts of Australia. It grows about 20–24 cm (8–10 in). They feed on plankton and small crustaceans.
As with seahorses, the male leafy sea dragon cares for the eggs. Leafy sea dragons take about 28 months to reach sexual maturity.
Sea dragons are difficult to maintain in aquaria. Success in keeping them has been largely confined to the public aquarium sector, due to funding and knowledge that would not be available to the average buff.

Weedy Sea dragon :

Weedy Sea dragons are only found in southern Australian waters. It also belong with family Syngnathidae. Weedy Sea dragons can grow to about 46cm in length. They are orange/red in color with numerous whitish spots on a lot of their body and along their tube shaped snout. The weedy sea dragon is very similar to the leafy sea dragon, but some extent weedy sea dragon is double sized than Leafy Sea dragon.
Weedy sea dragon does not have as many protrusions extending from its body, and appears more streamlined and sleek.

The Atlantic Ocean is the second largest of the world's five oceans

The Atlantic Ocean appears to be the second youngest of the five oceans.
The Atlantic Ocean is the second-largest of the world's ocean divisions.
It is located between the continents of North and South America, Europe, Africa and Antarctica. Which cover total area of about 106,400,000 square kilometers (41,100,000 sq mi), The average depth of the Atlantic Ocean is 3,900 meters (12,800 ft). The ocean bed is made up of hills, mountains, tablelands and valleys just as on dry land. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between the Americas to the west, and Eurasia and Africa to the east.

The Atlantic ocean is the busiest shipping ocean. The Atlantic ocean is the major artery between the Western and Eastern hemisphers. Economic activities include fishing, dredging of aragonite sands..in The Bahamas, and production of crude oil and natural gas in the Caribbean Sea, Gulf of Mexico, and North Sea.
