Bennett's Wallaby

Macropus rufogriseus

42° 3' N / 71° 34' W

Arsenault: Animal Adaptation for specific environment

Capybara
Hydrochoerus hydrochaeris
42° 3' N / 71° 34' W
This animal has webbed toes and hoof-like claws to help swim and stop them from sinking into mud. All of their facial features (eyes, ears, nose) are on top of their face to see when swimming.

Bactrian Camel
Camelus bactrianus

42° 3' N / 71° 34' W

This animal has a large amount of fat storage in it's humps to allow it to survive in the desert for days. It can also drink very quickly and store it for later.

Sullivan: Evidence of evolution

Masai Giraffe, Giraffa camelopardalis tippelskirchi 42°17'52.75"N 71°05'38.98"W.

The giraffe's long neck is a result of evolution. It allows the giraffe to reach leaves in tall trees.

Bactrian Camel, Camelus bactrianus 42°17'52.75"N 71°05'38.98"W.

As a result of evolution the camel has humps, which help it survive in the dry desert climate.

Sullivan: vestigial structure

Ostrich, Struthio camelus 42°17'52.75"N 71°05'38.98"W.

Emu, Dromaius novaehollandiae, 42°17'52.75"N 71°05'38.98"W.

Both the emu and ostrich have wings that are vestigial for flying.

Sharma : Different Types of Proteins

Hair contains the protein Keratin which is a structural protein

Egg whites contain Albumin which is a storage protein

This medicine is insulin which is a hormone that lowers blood sugar levels

Blood contains hemoglobin which is a transport protein

That is your biceps brachii which contain muscle cells with actin and myosin which are contractile/motor proteins

Sharma: Endothermic Organisms (2)

Domestic Dog
Canis Familiaris
42.288682,-71.634736

Domestic Indoor Cat
Felis Catus
42.243527,-71.644076

Natale: Mating Behavior

This is a Callinectes sapidus. It was found at 27°30'39.43" -82°42'43.12". While mating, the male holds the female against it for prolonged periods of time not only to mate, but to protect the female while she molts and also to prevent any other male from mating with her.

This is a Spheniscus demersus. It was found at 42°21'33.53" -71°02'56.42". The pair performs an extensive ritual consisting of circling around one another and hitting beaks against each other. The male will then proceed to climb onto the females back to mate.

Natale: Viviparous organism

This is a Macropus rufus. It was found at 42°03’56.67” -71°35’07.71”.

Chen: Mutualism

Clownfish (Amphiprion ocellaris) and Sea Anemone (Heteractis magnifica)
42.362983,-71.051331
The Clownfish and the Sea Anemone have a mutualistic relationship. The Clownfish benefit from the Sea Anemone because it provides the fish the protection from predators. The Sea Anemone also benefits because the Clownfish provides it food and safety from other fish.

Chen: Mating Behavior

African Penguin
Spheniscus demersus
42.362983,-71.051331

Chen: Evidence of Evolution

Surinam Toad
Pipa pipa
42.362983,-71.051331
The Surinam Toad lives in water that is often with little oxygen, polluted, and murky. Therefore, the toads have evolved their colors so they can camouflage on the bottom and wait for their prey which include small fish and underwater insects.

Leafy Seadragon

Phycodurus eques

42.362983,-71.051331

The Leafy Seadragon evolves to look similar to seaweeds and algae in their habitats. This helps the seadragon by protecting them from predators and other organisms that try to approach them.

Chen: Instinctual Behavior

Atlantic Salmon
Salmo salar
42.362983,-71.051331
Atlantic salmon are born in freshwater areas and will migrate on their own to saltwater areas to better suit their lifestyles. They manage to move through different areas easily and safely.

Blueback Herring
Alosa aestivalis
42.362983,-71.051331
Blueback Herring will demonstrate a 'schooling pattern' in that they will travel in large groups to avoid predators and reproduce a large amount. This benefits the blueback herring in a great way.

Chen: Radially Symmetrical Individuals

Purple Sea Urchin
Strongylocentrotus purpuratus
42.362983,-71.051331

Green Sea Urchin
Strongylocentrotus droebachiensis
42.362983,-71.051331

Chen: Population

Atlantic Silverside
Menidia menidia
42.362349,-71.051331

Sheepshead
Archosargus probatocephalus
42.362349,-71.051331

Chen: Asexual Reproduction

Flower Hat Jelly
Olindias formosa
42.362349,-71.051331
Flower Hat Jellies reproduce in 'blooms' which is a reproductive event that produces many identical jellies.

Japanese Sea Nettle
Chrysaora melanaster
42.362349,-71.051331
The Japanese Sea Nettle reproduce asexually. The males release sperm which are caught by the females to fertilize the eggs. The fertilized eggs will continue to grow and develop. Eventually, the eggs are released into the ocean where the jellies will attach themselves to a solid surface and undergo asexual reproduction and produce identical copies.

Chen: Aposematic Coloration

Blue Poison Dart Frog
Dendrobates azureus
42.362349,-71.051331

Dyeing Poison Arrow Frog
Dendrobates tinctorius
42.362349,-71.051331
Both the Blue Poison Dart Frog and the Dyeing Poison Arrow Frog use their bright colors to warn predators. This is beneficial towards the frogs to avoid their predators from approaching them.
