Shellfish Shellfish is a culinary and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some kinds are found in freshwater.

- Boxfish are a type of fish belonging to the Ostraciidae family of fishes. They are box-shaped and usually on the small side, not often exceeding five inches (12 cm) in length. A layer of bony plates on the scales helps to protect them against attacks by larger predators.

Echinoderms Echinoderms are also called as Echinodermata and spiny skinned animals. Echinoderms are entirely marine species. They are mostly seen in the inter-tidal zones deep in the ocean and they are also found in the cold and tropical seas. Echinoderms have several unique features that are not found in any other animals.The body wall has a limestone skeletal system called as Stereom. The echinoderms have a special ligament that helps them to stiffen or loosen their body without spending much energy. The males and females echinoderms are separate.ome species of the Echinoderms like starfish are carnivorous, others like sea cucumbers are detritus foragers, and some like basket stars are plankton feeders. Echinoderms have the ability to regenerate their missing organs.

Ray-Finned Fishes (Class Actinopterygii) This separates them from the lobe-finned fishes (Class Sarcopterygii, e.g., the lungfish and coelacanth), which have fleshy fins. Ray-finned fishes make up about half of all known vertebrate species. This group of fish is very diverse, so species come in a wide variety of shapes, sizes, and colors. The ray-finned fishes include some of the most well-known fish, including tuna, cod, and even seahorses. Classification: 1  Kingdom: Animalia. 2  Phylum: Chordata.

Shellfish Although the term is primarily applied to marine species, edible freshwater invertebrates such as crayfish and river mussels are also sometimes grouped under the umbrella term shellfish. Although their shells may differ, all shellfish are invertebrates.

- The class Chondrichthyes consists of the cartilaginous fishes, including sharks, batoids (rays, skates, guitarfish, and sawfishes), and chimaeras, or ratfishes. A diverse group comprising more than 700 species, Chondrichthyans are found throughout the world's oceans and in some freshwater environments.harks, rays, and chimaeras or ratfishes make up the cartilaginous fishes (Chondrichthyes), one of the two major groups of fishes. The other major group is the ray-finned fishes (Actinopterygii). Unlike the more familiar rayfinned fishes, the cartilaginous fishes have skeletons composed entirely of cartilage.

- Material, thickness and speed of the volcanic flows The volcanic flows reached 12 -18 km from the vents in the volcano. The flows had locally sometimes a thickness of 200 meters at a distance of 5 -15 km from the top of the Pinatubo.

Starfish Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars.s well as the starfish, the echinoderms include sea urchins, sand dollars, brittle and basket stars, sea cucumbers and crinoids. The larvae of echinoderms have bilateral symmetry, but during metamorphosis this is replaced with radial symmetry, typically pentameric.

List of types of seafood Shellfish include various species of molluscs, crustaceans, and echinoderms. Historically, sea mammals such as whales and dolphins have been consumed as food, though that happens to a lesser extent in modern times.

- Cartilaginous fishes (Class Chondrichthyes, from Greek chondros, cartilage, and ichthos, fish) are a class of aquatic, gill-breathing, finned vertebrates (animals with a vertebral column or `backbone'), equivalent to the bony fishes (Class Osteichthyes: osteos, bone, and ichthos, fish).artilaginous fishes (Class Chondrichthyes, from Greek chondros, cartilage, and ichthos, fish) are a class of aquatic, gill-breathing, finned vertebrates (animals with a vertebral column or `backbone'), equivalent to the bony fishes (Class Osteichthyes: osteos, bone, and ichthos, fish).

Osteichthyes The vertebrates include various animal groups such as fish, amphibians, reptiles, birds, and mammals. A fish pertains to any gill-bearing animals lacking limbs with digits. Osteichthyes (bony fish) is one of the taxonomic superclasses of fish. The others are chondrichthyes (cartilaginous fish) and Agnatha (jawless fish). Osteichthyes includes the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii).

Crayfish Crayfish, also known as crawfish, crawdads, freshwater lobsters, mountain lobsters, mudbugs or yabbies, are freshwater crustaceans resembling small lobsters, to which they are related; taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams where there is running fresh water, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species such as Procambarus clarkii are hardier.

Chondrichthyes Chondrichthyes (/kɒnˈdrɪkθɨ.iːz/ ; from Greek χονδρ- chondr- 'cartilage', ἰχθύς ichthys 'fish') is a class that contains the cartilaginous fishes: they are jawed vertebrates with paired fins, paired nares, scales, a heart with its chambers in series, and skeletons made of cartilage rather than bone.he class Chondrichthyes has two subclasses: the subclass Elasmobranchii (sharks, rays, skates, and sawfish) and the subclass Holocephali (chimaeras).

Starfish Although starfish are invertebrates, they do have a kind of skeleton. The bodies of starfish are composed of calcium carbonate plates, known as 'ossicles'. These form the endoskeleton, which takes on a variety of forms such as spines and granules. They have a primitive nervous system, but not a brain.

What Is a Starfish? Answer: The word starfish refers to about 1,800 species of marine animals that are star-shaped. The common term starfish is confusing, though. Starfish aren't fish-finned, tailed animals with backbones-they are echinoderms, which are marine invertebrates. So scientists prefer to call these animals sea stars.Sea stars come in all sizes, shapes and colors.tarfish aren't fish-finned, tailed animals with backbones-they are echinoderms, which are marine invertebrates.
