"We think this because, although we [went] out in the spring and Leathesia is normally found in this area in the fall, this seaweed has all the characteristics of the native species, including a pale brown color and a globular shape. Also the sea squirt has two siphons to exchange water and filter feed. This specimen does not have any siphons."
"This is a Common Periwinkle compared to a smooth periwinkle. The color is another thing that separates Common Periwinkles from the rest."
"There are alternating thorns on every joint of the plant. This distinguishes it from the Common Barberry which has longer thorns and three or more on each joint."
"Yes they are both round and similar in shape, but the color in the Morrows Honeysuckle are much darker than the berries that we found...."
"The leaves were in a compound pinnate arrangement, and had a sort-of glossy sheen to them that shone in and out of the sun. The leaves were bright green on the top and a softer, pastel green on the underside...."
"Our first piece of evidence that we did NOT find multiflora rose is that the berries of this plant were larger than the pea-sized hips of multiflora rose. These berries are more soft and juicy and you can see the seeds inside when you hold them in a sunbeam. Multiflora rose hips are harder and more dense...."
"The stem to purple loosestrife is always square. I cut a part of the stem to show the shape, like my teacher Four Seasons did, to prove that it is the same plant...."
"At first glance, we thought this plant's thin stems and thin leaves looked like European naiad. We quickly ruled the invader out, though, after seeing the smooth edges (European naiad has toothed, spiny edges) and distinct whorls...."
"The Japanese Knotweed’s Species I.D card said that during September and October there should be white flowers on the plant. On the plant pictured above there are no flowers. When not seeing any signs of flowers, we knew that it was not our plant. This time of year there should be flowers in finger shaped bunches...."
"The leaves of our plant have toothed edges with a waxy look about them, whereas the leaves of the Morrow's Honeysuckle are smooth-edged and have fuzzy hairs situated on the bottom of each leaf...."
I think I found the Northern Sea Star because the spines on this star are in rows. If the spines are in rows that means it's a Northern Sea Star. If they are scattered that means it's a Common Sea Star.
The leaves are 12 cm wide. The leaves of Japanese Knotweed are typically 12- 18 cm wide.
The stem of Japanese Knotweed is hollow. The stem of our plant is hollow.
"The leaves are in between 5-12 cm, ours is approximately 7 cm, and are alternating in pattern. The shape of the leaves are simple with the edges of the leaves are lobated, meaning that they have spots that are concave and then are convex...."
"The shape of this star is different than the northern sea star. This one has shorter arms, and more webbing between the arms...."
"Unlike a true albino, there were dark striations outlining each white section resembling a mosaic pattern...."
"We think we found garlic mustard because (non-rosette) leaves were alternate along the stem, triangular, coursely-toothed, and averaged 5-6 cm. The tallest plants we sampled were about 1m. After tramping through to sample, we all left smelling like garlic/onions...."
"This photo shows the zigzag stem, smooth-edged oval leaves, and white flowers/seeds that are characteristic of Japanese knotweed. Using my hand as scale you can see that the leaf is not large enough to be giant knotweed. It also was not hairy on the underside...."
"I think this is a native waterweed and NOT hydrilla because there are only 3 leaves per whorl (hydrilla has 4+ per whorl). The leaf edges of this plant are smooth. Hydrilla has toothed edges...."
"The specimen was dark with light orange spots on the topside. It had a bright orange underside. It's rear end was puckered and seemed to suction when moving...."
"We think this is a rock crab because it has 8 spines on each side of its carapace. The shell is covered with lots of purple and dark red dots. Rock crabs have a white belly and white inside of their legs like this one does."
"On the under side of the needles, I could see the two white racing stripes. You can also see here that the needles attach with a small stem. On balsam fir which look much like a hemlock the needles look they are attached with a suction cup. So I'm pretty sure this is hemlock."
"We think that one of the Green Crabs we found was a female because the tail tucked underneath was quite wide. We did not find any females carrying eggs, but we think they are reproducing because the live crabs we found were very small and so we think they were quite young."
"In this photo, you can see the difference in the color of the crab's claws. The green crab, on the left, has darker claws that are brownish/black. The possible rock crab has lighter colored claws that look grayish/red."
"I thought this was it at first because I saw the berry, but then noticed it still wasn't it."
"If you look close you can see the there are spikes on the sea star and they are lined up in a straight line. This is evidence that this species is the Northern Sea Star."
"Using its tube feet to cling on to the side of the container and its green spikes show what type of urchin it is."
