Invertebrate

multiple branches of science to come to his conclusion. A lot of his ideas were similar to those of Jean Baptiste Lamarck, an obscure character in evolutionary history. Lamarck was appointed professor of invertebrates. In that moment, there was few study on insects. He wrote a series of books about invertebrate zoology and paleontology. Though other scientists in his day hinted at the possibility of evolution, Lamarck declared it forthright. He was discredited by his peers and died a poor man.…

Coral Reef Bleaching Coral reef bleaching, which is the whitening of diverse invertebrate taxa. The cause of the whitening is “from the loss of symbiotic zooxanthellae and/or a reduction in photosynthetic pigment concentrations in zooxanthellae residing within the gastrodermal tissues of host animals.” (P.W.Glynn) The reason why coral reef bleaching is such a concern is because the “consequences of bleaching large numbers of reef-building scleractinian corals and hydrocorals.”(P.W.Glynn)…

aboard the oceanographic research vessel Glomar Challenger. An objective of this particular cruise was to investigate the floor of the Mediterranean and to resolve questions about its geologic history. One question was related to evidence that the invertebrate fauna (animals without spines) of the Mediterranean had changed abruptly about 6 million years ago. Most of the older organisms were nearly wiped out, although a few hardy species survived. A few managed to migrate into the Atlantic.…

differences such as anatomy, size, reproduction and lifespan, location, and behavioral patterns. The biggest and most notable characteristics that octopi and squid share in terms of anatomy is that both have a beak to eat with and are invertebrates. Invertebrates are animals that do not possess a single bone in its body. This is a characteristic that all animals belonging to the Cephalopoda class share, although, “Squids possess a stiff structure known as a pen that acts as a flexible…

Welcome to the most colossal biome on Earth, the marine! This ginormous place on Earth is home to many plants and animals within its many oceans and three different levels. Pacific, Atlantic, Arctic, Southern, and Indian are the five main oceans on this planet. Each ocean is separated into three levels, known as euphotic, disphotic, and aphotic. The euphotic zone is also known as the sunlight zone, this is the top layer of the ocean and it receives almost all of the sun's rays. The next section…

Jellyfish is a free-swimming animal with a jellylike- bell or saucer shape body. Typically they are transparent and have stinging tentacles around the edge and considered as invertebrate species, meaning that they do not have backbones. The kingdom they are classified to is animalia(eukaryotic and multicellular organism) and belongs to phylum cnidaria, which is a taxonomic rank below kingdom and above class. Theoretically, members of Cnidaria have life cycles that alternate between asexual…

The first process is when nerves in the skin sense something harmful and communicate that information to the spinal cord. There the motor neurons activate movements that cause us to react; this is the physical recognition of harm known as nociception. Nearly all animals even those with simple nervous systems experience it because without it animals would be unable to avoid harm and their survival becomes threatened . The second process is called conscious recognition. In humans, this will occur…

Comb Jellies are a type of jellyfish that have eight “comb rows” of cilia that are fused together and arranged along their sides. In Figure 1, the fused cilia can be seen easily along the length of the red lines. The cilia are used to propel the animal through the water. Some of them move through the water by doing a flapping motion with their lobes or undulations of the body. They usually have two tentacles, but lack stinging cells. To capture their prey by using sticky cells, called…

Most people are familiar with the Venus flytrap. Small and ominous-looking, the plants are commonly sold as novelties, and many a curious child (or adult) has triggered its ..……. (baneful, sinister, doomful, malevolent) traps with a pencil to see its amazingly rapid response. However, carnivory in plants is not limited to the famous Venus flytrap. In fact, there are more than 600 carnivorous plant species, and the ability to catch and digest ………(dupe, prey, victim, quest) has evolved…

Allan and Flecker’s study notes that, “the greatest invertebrate diversity is located within a few groups, including several minute, interstitial phyla… these taxa are both the least well described and most difficult to identify” (Allan and Flecker 1993). Because of the secluded nature of the ponds, and the…
