Sepiida

Taxonomic Classification:

Kingdom:    Animalia

Phylum:    Mollusca

Class:    Cephalopoda

Order:    Decapodiformes

Family:    Sepiida

Nutritional Requirement:

The Cuttlefish is primarily carnivorous and it will mainly eat small crustaceans (like shrimps and crabs) but the Cuttlefish will also eat small fish. The Cuttlefish hunts it prey by first blending in with the environment, and then surprising and killing its prey.

Growth and development:

The Cuttlefish, after hatching, will live its entire life on its own and without a mother or father. The Cuttlefish will grow into an adult in a short time and it has a full size of 15cm - 50cm and 3kg - 10.5kg. The Cuttlefish will also only live 2-3 years

Behavior:

The predators of the Cuttlefish are large fish, sharks, and even other cuttlefish. In order to protect themselves against these predators, the Cuttlefish will project ink and flash numerous colors in order to confuse predators.  

Reproduction:

Male Cuttlefish during mating season will turn different colors in order to attract females. A female Cuttlefish will lay about 200 eggs and then die immediately afterward.

Evolutionary Origins:

Cuttlefish evolved from the same common ancestor as squids and octopi.

Habitat:

Coastal and deeper waters

Phylum:    Chordata

Class:    Mammalia

Order:    Carnivora

Family:    Felidae

Genus:    Lynx

Nutritional Requirement:

The bobcat is carnivorous and will only hunt and eat other animals. In warmer months the bobcat will mainly hunt small mammals like rabbits, hare, mice, birds, and they will also eat lizards on occasion. In colder months bobcats will hunt deer or fresh carrion.

Growth and development:

Bobcat kittens are born blind and won’t open their eyes until a period of at least 10 days has passed. Young bobcats will feed on their mother’s milk until they gain the strength to eat meat. Once the young bobcat learns how to hunt on it own, the bobcat will leave it’s mother and will be considered an adult, this milestone usually happens 8 months after birth. A full-sized bobcat is about 65cm - 100cm, weighs 4.1kg - 15.3g, and will live 12-15 years.

The bobcat is mainly solitary and is also nocturnal meaning it will only be seen awake during the hours of the night. Bobcats can be seen hunting during hours of dawn and dusk and sleeping in rock crevices or hollowed out trees during daylight hours. Bobcats will mark their territory with urine and will generally avoid other bobcats as to not get injured in a fight.  

Reproduction:

Bobcats have a mating season in Winter and this is one of the only times two bobcats will be seen in close together. Males and females both mate with multiple partners and females will have a gestation period of 8-10 weeks. The bobcat kittens are usually born in a den in litters of 3.

Evolutionary Origins:

Bobcats are most closely related to the larger and more northerly dwelling Canadian Lynx and they likely both have the same common ancestor.

Behavior:

The Bandicoot is primarily solitary and nocturnal. This means the Bandicoot will spend it’s daylight hours hiding in bushlands and creek beds and then it will spend its nighttime hours hunting for food. Due to Bandicoot’s small size, it has a large number of predators including large birds, foxes, snakes, wildcats, and humans. This large selections of predators for the Bandicoot have played a part in the Bandicoot endangered status.

Reproduction:

Bandicoots are mainly solitary creature but they will meet up with other Bandicoots in order to mate. Bandicoot’s don’t have any specific mating season and they have the shortest gestation period of any mammal with the young being born just 12 days after conception. A female with normally give birth to a litter of 3-6 young and she will nurse them in her pouch until they are strong.

Baby peafowl, also known as Peachicks, are born weighing 3.6 ounces and will become fully feathered within a couple of weeks. It takes about 3 years for a peachick to develop into a peafowl and they can have a lifespan of 12-20 years in the wild and 40-50 years in captivity.

Behavior:

Peafowl will nest on the ground and roost in trees most of the time. Peafowl is believed to be polygamous meaning a single male will have more than one mate. When provoked peafowl will get into territorial fights and use thorns on their legs to fight.

Reproduction:

When trying to attract a mate male peafowl, also known as peacocks, will spread their train feathers and make the feathers shake. If the Peahen is impressed by the peacock’s dance she will go and join the peacock’s harem. Peafowl reaches sexual maturity at 2-3 years old and peahen will lay 6-12 egg from April to September after mating with a peacock.

The Bumblebee!

Scientific name:

Bombus

Taxonomic Classification:

Kingdom:    Animalia

Phylum:    Arthropoda

Class:    Insecta

Order:    Hymenoptera

Family:    Apidae

Genus:    Bombus

Nutritional Requirement:

The Bumble Bee’s diet consists of pollen and nectar from flowering plants. Worker bees will collect the nectar and pollen and bring it back to it’s colony for other non-worker bees to eat. By collecting food Bumble Bees help to play a big part in pollinating flowers.

Growth and development:

The fact of whether a bumble bee egg is fertilized or not determines the type of bumblebee that will be born. Fertilized eggs produce females (queens and workers), and unfertilized eggs produce male drones. Once an egg hatches the bee larvae will take about 5 weeks to go through the stages to reach adulthood. Once a bumble bee is fully grown it will be about 1.9-3.8 cm and it will live for about a year.

Behavior:

Bumblebees live in large colonies and are primarily active during daylight hours. A bee colony consists of a queen bee responsible for reproduction, drone bee responsible for fertilizing the queen, and worker bees made to maintain the hive’s well being. Bumblebee are only hostile if around a nesting site and females can sting multiple times if provoked.

Reproduction:

The queen bee is responsible for reproduction in a colony and will produce primarily in the winter. Pollen stimulates the ovaries of the queen bee to produce eggs. Eggs are laid in batches of 4 to 16 eggs on a ball of pollen.  

Evolutionary Origins:

Bumblebees evolved from corbiculate bees.

Habitat:

Quiet Forests and Pastures
