Echinodermata
The phylum that has organisms known for a hydrostatic skeleton is the phylum Mollusca. This group of animals, such as snails and squids, have a fluid-filled cavity that provides support and structure to their bodies.
Leeches belong to the phylum Annelida, which is characterized by segmented bodies, a lack of internal or external skeleton, and bilateral symmetry. Leeches also have a closed circulatory system, a well-developed nervous system, and a body covered in a layer of cuticle.
The stingray is a vertebrate, scientifically classified in the phylum Chordata. Its skeleton is made of cartilage instead of bone, but it still has a vertebrate skeleton. AND IT IS A CHORDATEStingrays are vertebrates
The phylum name Echinodermata means "spiny skin," derived from the Greek words "echinos" (spiny) and "derma" (skin). This name refers to the presence of spiny, calcareous skin covering the bodies of echinoderms, including sea stars, sea urchins, and sand dollars.
Yes, stink bugs are invertebrates since they do not have any form of internal skeleton.
The liger is a vertebrate (internal skeleton) and belongs to the Phylum Chordata.
By definition, arthropod skeletons are external, a defining characteristic of the phylum; having both an internal and external skeleton would be redundant.
Yes, all crabs are invertebrate, as they lack an internal skeleton and vertebral column (spine). This is a defining characteristic of their phylum, Arthropoda. Instead of an internal skeleton they use an outer skeleton or exoskeleton.
Its when a sea animal forms a skeleton from calcium carbonate (CaCO3). Calcium carbonate is dissolved in seawater, but less soluable at higher temperatures. The majority of animals with calcareous skeletons, such as corals, are found in the tropics where it takes less energy to get it out of the seawater
No, tigers are chordates - phylum Chordata, a different phylum than Arthropoda (the arthropods). Pretty much anything with an internal skeleton and backbone like mammals, birds, reptiles, amphibians, will be chordates. Arthropods have their skeleton on the outside (exoskeleton), like the insects or crustaceans.
No, rabbits are chordates - phylum Chordata, a different phylum than Arthropoda (the arthropods). Pretty much anything with an internal skeleton and backbone like mammals, birds, reptiles, amphibians, will be chordates. Arthropods have their skeleton on the outside (exoskeleton), like the insects or crustaceans.
It is the ossicles :)
Yes, lobsters are invertebrates, belonging to phylum Arthropoda. They have an exoskeleon (external skeleton) and no vertebrae. By contrast, vertebrates like us humans have an internal skeleton including a backbone (vertebral column).
Arthropoda
The phylum that has organisms known for a hydrostatic skeleton is the phylum Mollusca. This group of animals, such as snails and squids, have a fluid-filled cavity that provides support and structure to their bodies.
Any of numerous aquatic, chiefly marine invertebrate animals of the phylum Porifera, characteristically having a porous skeleton composed of fibrous material or siliceous or calcareous spicules and often forming irregularly shaped colonies attached to an underwater surface.
All mammals have an internal skeleton
