One important discovery Shubin made is Tiktaalik, which is a 375 million year old fossil. Tiktaalik is a fish that has scales and gills, but its head is flattened like that of a crocodile. Like most fish, Tiktaalik’s fins have ray bones enabling them to paddle in water, but the most amazing thing about it is that it has interior bones which allows it to lift off of the sea floor, something unordinary for a typical fish. It would use its limbs for support like a tetrapod. Shubin shows how fin structures of fish like Tiktaalik mark the beginning of the evolution into the mammalian paw and opposable thumb structures in the hands of today’s primates.

One such biological species which is going extinct is the angel shark. The Angel sharks are flat-bodied sharks, very ray-like, with broad pectoral fins that bury themselves in the sand or mud with only the eyes and part of the top of the body exposed. They have a blunt snout
There are many different species of Algae which can range in size from microscopic to a couple meters long. Phytoplankton is at the bottom of the food chain and is eaten by small crustaceans which are called Zooplanktons. Zooplanktons are eaten by fish, invertebrates, mollusks, ducks, and turtles. • Plants: Around fifty species of food and shelter providing plants- Plants along with Algae provide the Rideau River with oxygen. Some of the plants in the Rideau River are carnivorous.
Although they prefer fresh food they will eat basically anything that they can get their claws on, even if it’s dead. (As is evident in their desire to get at the bait in the lobster traps!). The main diet of a lobster is crab, mussels, clams, starfish, sea urchins and various marine worms. They are also known to catch fast moving animals like shrimp, amphipods (also known as“sandfleas”)and even small fish Reproduction: Lobsters mate in a shelter during the summer when the female has just moulted and her carapace is still soft. The male turns the female over on her back and transfers his sperm cells into the female using his first pair of swimmerets (gonopods).
Sea anemones, from the Phylum Cnidaria, can be distinguished from feather stars, from the Phylum Echinodermata, due to their distinct morphology. Most sea anemones have a body column, with a fleshy pedal disc at the bottom and a mouth ringed with stinging tentacles on the top ("Sea Anemones (Actiniaria) On The Shores Of Singapore"). In contrast, feather stars have pinnate (feather-like) arms that extend from a cup-shaped central body called the calyx; numerous slender branches called pinnules branch out from the left and right sides of each main arm ("Feather stars (Crinoidea) on the Shores of Singapore"). Tube feet (podia) further branch off from the pinnules and arms, creating the characteristic "feather-like" look of the feather star ("Feather stars (Crinoidea) on the Shores of Singapore").
