Rene Ismail McKenna - C 9th Grade Biology PBA American Lobster - Homarus americanus Ecosystem/Ecology of Homarus americanus Adult American lobsters tend to dwell in depths of below 50 meters. However, some can live at depths of about 750 meters. They can weigh up to 44 pounds and reach a length of about 25 inches, however they are typically around 2 feet long and weigh 3 pounds. The American lobster’s preferable habitat is on rocky surfaces covered with algae, because algae attract animals that the lobsters prey on. This habitat allows the lobster to hide within the cracks, where it can hide from predators in its environment such as flounder, cod, crabs and eels.
Cephalopoda Introduction: Invertebrate animals which belong to mollusks which means “head foot” and characterized by large head and modified feet. This group includes octopuses, squid, cuttlefish and nautiluses. Members of cephalopods are characterized by their ability to quick change their color as well as changing the texture and shape of their bodies as a means of camouflage. Today there are about 800 living marine species of cephalopods which are found in all of the world’s oceans, from the tropics to the near freezing water at the poles. Description: The name cephalopods which means head-armed were given this name because these animals have several arms around their protruding mouth.
Fortunately their small size means that two or three can be kept comfortably in a 2 or 3 gallon aquarium. Of all the fish discussed here, these are probably the best for a large unheated bowl or small unheated aquarium. Zebra Danio, Brachydanio rerio: Not Ideal Most danios are small, the zebra danio being 1¾ inches in length, and they are tolerant of a wide range of temperatures. Their natural temperature range is 64-75F. However, they are fast swimmers and like to school which makes keeping them in a tiny aquarium
There are more than 900,000 different known species of insects on the planet, with many more yet to be discovered. These insects make up approximately 80% of the planets animal life. Carausius morosis is a member of the Order Phasmatodea and Family Phasmitidae. The Order Phasmatodea is made up of the stick and leaf insects, a relatively small group of insects numbering about 3,000
Horseshoe crabs are marine living fossils, probably traced back to 485 million years ago. There are two horseshoe crab species found in Hong Kong. Horseshoe crabs are an ancient marine chelicerates, identified as the Class Merostomata and Order Xiphosura. The animals are identified by the having appendages around their middle of the mouth and their swimming legs at their end of their body. They are in close linkage with trilobites and arachnids which are spiders and scorpions.
They lack digestive tract, mouth and senory organs, they have unique body extension called microtiches which help in absorption of host nutrients. They have scolex which is provided with suckers and often with hooks for attachment. More than 10,000 species of tapeworms are known to science. The most common species of tapeworm in humans are fish tapeworm, beef tapeworm, pork tapeworm, dwarf tapeworm, dog tapewom, uniocular hydatid and multiocular hydatid. 1.
Besides these, when living in swamps or rivers, they will be also co-existing with shrimps and fishes. They are rarely alone, as they move in large groups, especially when laying eggs. They are also used as food for indigenous people, so at certain times, the conch will be in abundance but then gradually drop as they are caught and eaten. The average life span for Pomacea urceus is 2-4 years, with some living longer (Holswade 2013). Behavior: Pomacea urcues is an amphibious.
A Smithsonian researcher led a team that discovered 18 new species of spiders in Madagascar that looked like pelicans. The spider is formally known as Archaeids which has an extended, arching carapace and two extra-long mouthparts, the chelicerate, which creates an illusion of a neck and a beak that gives the arachnid a pelican appearance. National Geographic described the spider as quiet as an owl, quick as a cobra, small as a grain of rice, and is more like a venomous pike when it strikes its prey. The Smithsonian noted that the purpose of the unusual appearance of the Archaeids is to make it prey hunting easier. The pelican spider eats only spiders, not other insects.
Drosophila is a genus of small flies, belonging to the family Drosophilidae, whose members are often called “fruit flies”. One species of Drosophila in particular D.melanogaster, has been heavily used in research in genetics and is a common model organism in developmental biology. The entire genus, however, contains about 1,500 species and is very diverse in appearance, behavior, and breeding habitat. Scientists who study Drosophila attribute the species’ diversity to its ability to be competitive in almost every habitat, including deserts.

Page 9 Carpenter Bee The carpenter bee is a member of the Xylocopinae family. The Carpenter bee can be found all over the world. There have been known to have 500 species of carpenter bee. It has a behavior to build nests in burrows. They build these nests in dead wood, bamboo, and other dead timber.
For example, this Octopus has a beak, nine brains, eight boneless legs, large eyes, and three hearts. The beak is located in the head part of its body, and is made out of the same materials as human fingernails (Roumanis, 2015). This Octopus, being fairly large, has nine brains to control its body. Having nine brains allows it to navigate all eight legs. The Giant Pacific Octopus has three hearts for two different tasks.
These birds were listed as endangered on March 11, 1967 and also rely on the basin for crayfish to eat. In addition to birds, plenty of fish can be found in the basin and fishermen frequent the basin in search of Tilapia (3). Tilapia can be found by the hundreds in the basin along with corvina and an occasional striped bass, mullet, croaker, or sargo (3). The endangered pupfish, though rare, also rely on the basin for survival (10). Pupfish are also the only native species in the Salton Sea, thriving in shallow bodies of water with a high salt and heat
The Northwest Coast’s main food source was salmon, thanks to the Pacific Ocean they had plentiful amounts of it. Fishing was usually done in the summer, and stored for the winter, but they were able to fish all year long. Although they did eat and catch other aquatic animals, including whales, salmon was the easiest to catch and the most convenient to store for long periods of time. The Pacific Ocean supplied the tribes with fish, crab, seaweed, whales, mussels, some sea mammals, and fish oil. The people had many methods of catching the fish, the most drastic one was by using harpoons.
The trichechus most commonly known as the manatee is a large aquatic mammal with ancestors dating back to 45 million years. The modern manatee has been found in fossil evidence to have existed for at least 1 million years. Living in shallow bodies of fresh and saltwater the manatee is mostly a gentle solitary animal, with highly developed social skills. While different variations of the manatee live across the world, all manatees are slow moving herbivores with very few natural predators. While the manatees are rather slow animals they are agile and can easily maneuver underwater.
To be specific, seahorses eat brine shrimp. They can eat up to 3,000 brine shrimp per day! The food that they eat quickly passes through their digestive system, like garbage going down a garbage chute. In that case they get hungry pretty quick because the food they eat doesn’t sit in their stomach like our food does. That is only because they don’t have a stomach.
