The grade seven science students of Mary Baer ex- plored the animal life in Boylson’s vernal pools as part of a mutli-disciplinary activity. The students would like to share their sketches and samples of their research with Lydia H. the community so that others might also learn about the organisms of these temporary wetlands. Martha M.

The scud is a small amphipoda that is also known as a side swimmer. It is debris on the back of it. They get their name by the debris on its back which looks The Fingernail Clam is usually no larger then one-half inch. Their shell lacks squares on the dorsal surface of its back. A very distinguishing feature of the As an adult, they tend to be a greenish-brown type color with red dots that about 1/4 of an inch to 1 inch in length. Scuds come in different colors from like a log cabin. They stay in the “cabin” that they made in their larva stage. Having growth rings and is whitish to brown in color. They can be found throughout the frog is the yellow or sometimes orange color on its back legs. The frog is only Brian C. Emerald F. run down the body.

They stay in their larva stage until the pool dries up or they weeks. Throughout the summer and fall, the larvae developnto the Eft stage ponds, or vernal pools. They live on the bottom because they are highly same pool. Most frogs don’t make it to the point of life where they die. become an adult. There aren’t many predators in the vernal pool so it is a safe by absorbing their gills and growing legs so they can move onto land. Years sensitive to light. Scuds like cold water and need a large amount of oxygen. Usually they are eaten before they die of natural causes. place for them to live. later, as adult newts, they return to the water and repeat the cycle. Grady B. Michael M. Billy H. Nick W. Christi W.

They have two short legs, which are used for The Wood Frog is small, about 3.5 cm and it can be brown tan or copper in Rana catesbiana. The Bullfrog has strong and long legs for jumping. The Bullfrog hatches from an egg, which is laid in water, on a plant or even underwater. As ing stage takes ten to twenty days. These Bullfrog tadpoles live in aquatic feeding and two back legs with swimming hairs on them for swimming. There is a color. A black line runs from its snout to eye and it has a black mask from usually has black spots on its back and hind legs. Male Bullfrogs have bright nymphs, they feed on flatworms, tadpoles, and other small aquatic creatures. capsule-like covering over their entire body, which acts like a temporary lung behind its eye to its shoulder. The Wood Frog’s eggs hatch in 1-2 weeks. They habitats with plenty of vegetation and shallow areas. They can be found in slow yellow throats and all have large eardrums on the sides of their heads. At the The nymph loses its skin, or molts, many times during this stage. When it is because it holds oxygen inside. In order to stay underwater they cling onto twigs and remain in the tadpole stage for 60 days before it becomes a frog. As an adult, moving rivers, ponds, streams, shallow bays, and coves of lakes. Bullfrog beginning of summer hundreds of eggs are laid by the female Bullfrog in the ready to molt for the last time, it leaves its skin behind underwater. When it other things fully submerged. They also are tolerant of pollution and can be found in it eats mosquitoes, flies, beetles, and spiders. It is prey for birds, snakes, and tadpoles will not normally be found in vernal pools because they need a more vernal pool. The tadpoles have many predators, like birds, mammals, and even comes up out of the water, it uses its tiny claws on its feet to climb on a leaf. polluted ponds and lakes. The Water Boatmen can live in ponds, puddles, vernal raccoons. They attach their eggs to branches in the water of a vernal pool. permanent body of water to stay in until they grow lungs and the vernal pools pools and birdbaths. These insects are attracted to birdbaths because of the algae adult frogs. In two years, they metamorphose into small frogs . They develop After spending a few hours resting, it’s ready to fly. Dragonflies are found would dry up. Occasionally a vernal pool may hold water year round and in this Although they breed in water, they live in the woods. The Wood Frog can be that collects in them because of the unclean water. The Water Boatmen live under- into fully grown frogs and may be over 8 inches in size. Bullfrogs are found in worldwide. They are found near lakes, ponds, bogs, marshes, rivers, streams, case a Bullfrog tadpole may be found in this habitat. found in Canada and North America. water in permanent water during the winter and fly to vernal pools in midsummer. the United States. and waterfalls. A lot of them lay their eggs in vernal pools away from predators. Emil I. Cassidy B. David C. Ryan B. Corey C. Matt R. Emily B. Corrinne L. Joshua D. Mary D. Amanda B. Brittney C. Thomas B.

The Blue-spotted Salamander can be identified by the grayish black color on Fairy shrimp swim on their back upside down by making a current with their Eastern Box Turtles have a high-domed, rounded shell. Their jaw is slightly hooked The Fishfly is a small insect that usually ranges between 10-90mm. They The Giant Water Bug is 1.5 inches long and has a flat, oval body. The adults appendages. They are usually red-orange colored, but they can also be a translucent and their toes are only slightly webbed. They can be about 15cm x 10 cm in size. have 3 pairs of legs with tiny pinchers on the end of each. They are often a the back with the blue spots on its side, limbs, belly, and tail. The average size have a pair of wings and antennae below their eyes. The Water Bug offspring is whitish to gray, or blue to green. They can rest at the bottom of the pond, dart Also they have highly variable orange and yellow markings on their back. Box turtles light brown color. They have large chewing pinchers on their mouth and two of an adult is 3 – 5.5 inches long. During March or early April the Blue-spotted pale yellow in color for a few hours then darkens. When they are born they rapidly, or drift slowly. Fairy shrimp feed on algae, small animals, and detritus. To are omnivores, which means that they eat plants and little animals. The female box tails with hooks on them. On each of their abdominal sections they have long, Salamander migrates to a vernal pool and begins the annual breeding ritual. need special tubes to breath under water for the first few days. The parents will eat, they wave their gill-legs over the food and guide the food into their mouths. turtle lays 2-7 eggs in one batch. She then buries them in wet or damp land in the strand like appendages extending from both sides. Fishfly predominately live in The male releases a spermatophore from which the female takes in sperm Reproduction in Fairy shrimps takes place when the male clasps itself to the female leave a few hours after birth to let the Water Bug go on it’s own. They spend late spring. They hatch about 75-90 days after, which is normally in the fall. When ponds and shallow lakes and can be found in vernal ponds that hold water through her cloaca. The female lays the eggs in clusters of one to twelve and with its large, second antennae. The male and female stay clasped to each other much of their time above water to get more air because they are still young the egg hatches, the baby turtle has to find food and protect itself all alone. A box through most of the year. They have retractable breathing tubes that protrude they hatch in three to five weeks. During the late summer, the larvae change until the male shrimp dies. Then, the female carries the sack of fertilized eggs on her and soon get tubes on their backs to breath while under water. They live in turtle can live up to 40 years. You can normally find the Eastern Box turtle in the from their back. You would be most likely to find them under leaves at the pool so that they can live on land. They are fully grown in two years. The Blue- back for several days before she releases them. If she doesn’t release them, then ponds, marshes, lakes and slow moving rivers. They are found in all of North eastern U.S. in open woodlands, pastures and marshy meadows. These turtles are bottom. Fishfly larvae eat small insects and other aquatic animals. Some spotted Salamander can be found in forests and woodland areas where they are they will stay on her back until she dies. There are two types of Fairy shrimp found in America and Northern Canada normally near ponds, vernal pools, or streams. species stay a larva for 2 weeks; other species are larvae for up to 3 years. usually found hiding under logs, rocks, or leaf litter. the vernal pools of Massachusetts.
