Nocturnal Worms Case Study

You should also know how to avoid the pesky little critters. Identification and Life Cycle The appearance of bed bugs changes depending upon their age. After insemination, female bed bugs lay seven to 10 eggs after every blood meal they consume. These eggs are about 1 millimeter in length, making them the size of a pinhead. Females lay their eggs wherever they happen to be, so you may find them anywhere in your bedroom or other affected areas.

Manatees swim at about 5 to 8 kilometers per hour; much speedy swimming has been known in short bursts (up to 30 km/hour). Reproduction: Female manatees reach sexual maturity between five and nine years of age. Manatees typically breed once every two years. A female manatee usually seeks quiet area in which to give birth after a gestation of about 12 months. Generally, most births are of a single calf about 120 centimeters long with about 30 kilograms weight, although a few cases of twins have been documented.

In addition, observations showed that wild lion cubs were smaller than captive cubs of the same age and are thought to be because of various periods of starvation in the wild animals - a great factor displaying the impact of selective evolution. Schaller (1972) reported that a captive-raised, but wild-caught, lion cub was almost twice the size of wild cubs of similar

Alina Swanson Period 2 Mrs. Broad September 30, 2016 Isopod Lab Introduction: This lab is used to see if and how many of the Isopods like the light or the dark. Isopods also known as pill-bugs, roll into a ball when felt threatened. Isopods are very similar in body types as lobster, crabs, and shrimp. They all have compound eyes and antennae, but still sometimes do not always look alike. Isopods can be as long as 500 millimeters and can live as long as 4 years.

Female white sharks are thought to reach reproductive age at around 17 years. After an incubation period between 12 and 18 months the great white gives birth to between 4 and 14 pups. They are born roughly 1.2 meters long (3.9 feet) and weighing 50 to 60 pounds. Research has shown that the pups get their nutrients through eating unfertilized eggs and other embryos while in the uterus. Female great white sharks are thought to give birth to new litters every 2 or 3 years.

Time (mean + standard error) of nightcrawler earthworm (Lumbricus terrestris) spent in the dark, covered area of the 13 x 9 observing tray with damp paper towel. Expected time shows half of the timed five minutes (175 seconds) if the earthworms had randomly moved around. Time (sec) was measured with a stopwatch. 20 worms were observed to find the average. In this experiment, the earthworms spent more time in the dark area than the light (Figure 1).

They make a bellowing sound usually during mating season to attract females and to scare away other male rivals. B. Despite their cute and sleepy appearance, koalas can be quite feisty when they are provoked. 1. Koala claws are extremely sharp and long, so they will be able to climb trees.

The weight average of rainbow trout is about 3kg while individuals of rainbow trout can reach much heavier weights. Feeding habits: Rainbow trout are predators with varied diets depending on their life stages and availability of their natural diets. When they are young, rainbow trout will feed on small organisms such as zooplankton, and as they grow they feed on larval, pupal and adult forms of aquatic insects. They also eat fish eggs, small fish, crustaceans, mollusks, and insects. In vegetated habitats, rainbow trout often have the opportunity to eat terrestrial insects that fall into the water such as ants, beetles, and crickets.

Giant panda eat up to 85 pounds of bamboo every day. Giant pandas have back teeth that are very wide and flat. Their teeth help them grind bamboo. Giant pandas spent half of their days sitting down eating bamboo. They eat bamboo with their strong jaws and flat teeth while holding it with their paws and wrists.

Blizzards are an extended, severe snowstorms, in which winds must reach a minimal of 35 miles per hour for at least three or more hours.

The Bilby, before European settlement where widely spread over around 70% of the Australian mainland than reduced to extinction in some states of Australia due to habitat loss and competition and predation from many introduced species. Through many reintroduction programs across Australia there population has now raised. The Greater Bilby is a nocturnal bandicoot, the largest of the family of marsupials. They have an excellent sense of smell and sharp hearing which they rely on as they have poor vision. Bilbies are omnivores, they eat things such as seeds, spiders, insects and their larvae, bulbs, fruit, fungi and small animals.

Birth Rate: In the wild, there are single births about every 5 years Females have between five and six offspring in a lifetime. Gestation Period: 240 days Conservation Status: Endangered Along with the chimpanzee, the bonobo is believed to be one of the closes living relatives of the human. The bonobo shares 97% of the same DNA that makes up humans and the
