European Pilchard Sizes/Shapes/Description
The European pilchard is a small, oily, smoothly rounded, silvery fish, related to herrings.
A pilchard is a fish of the herring family that travels in schools along the coasts of Europe. It has flanks that are silver with a darker colored back and fins that are small with relatively large & triangular dorsal fins. This species is bilateral because if we were to cut it in half the two halves would be fairly similar. Pilchards are of great commercial importance as a food fish in many parts of the world. European Pilchards’ average length is around 15-20 cm and the tail itself is deeply forked with a dark/grey tint, similar to a herring. A herring is a silvery fish that’s mostly abundant in coastal waters and is of great commercial importance.
Habitat
Although it is a marine animal it mostly settles in Freshwater. A marine animal is any animal that lives in salt water or derives its food from saltwater environments. Freshwater is anything found in of fresh water; not the sea. The most common places to find European Pilchards are throughout Europe

Sexual reproduction is when sperm fertilizes a female’s ovum, different steps occur afterwards. An ovum is the female reproductive cell. The egg cell is typically not capable of movement, and is much larger than the motile sperm cells. The common area to reproduce for this species is in the Mediterranean and Black Sea. Mating seasons are September-June (Mediterranean Sea ) and June-August ( Black Sea ). Eggs can be carried for different amounts of time, the max amount of time recorded was two months. The male will fertilize the female’s ovum and both parents will then leave. Two to three days later the eggs will hatch in batches of 50,000-60,000 with a diameter of 1.5mm. As they hatch they will automatically migrate Northwards and stay together in a school and travel together until predators or their individual selves decide
Adapted for a wide range of aquatic habitats, various shark species inhabit shallow coastal habitats, deep-water ocean floor habitats, and the open ocean. With a wide selection to feed off of, as a whole the shark species feed on just about everything. Their diet consists of fish,
The nesting season runs from April to Mid-July. And, sometime between about 45 to 70 days after being laid, the eggs hatch, and the little ones make the perilous journey across the beach, into the surf, and eventually to the open ocean, desperately dodging predators along the way. Their survival at this point depends on sheer numbers and making it to the water before the hungry seagulls and crabs can snatch them up.
The mating season is year round and once they’re pregnant the, length of gestation is one hundred thirty days to one hundred ninety days. (The gestation for a human is two times longer.) They only have one offspring at birth. After birth the young latch onto the backs of their mother and stay until a year of age.
During that time the male will go out and seek a female usually in her burrow and that is when the life cycle
An environment with a lot of vegetation and their preys is ideal for them. They are perfect hunters with ability to stalk their prey with patience and stealth. They then capture their meals with one strong leap. These animals live in solitary or in territories. One unique thing about them is that the females do not share the same territory with each other. Territories for males usually tend to overlap. The territories are established with scent markings and the size varies extremely. The size ranges from twenty five to thirty square miles for males and five square miles for females (Sunquist & Fiona
For reproduction it is best to place one male in with 2-3 females. This will lower the rate of fighting compared to a one on one. Then the female will typically make a burrow 6-8 in. deep and lay her eggs there. The eggs will hatch about 60-70 days
California's severe drought has put millions of its trees in severe danger of dying. If you are living in an area suffering from similar or even less severe drought conditions, you can save your trees by following these simple guidelines. Most of them are already beneficial for your tree's health, but are absolutely essential when water is scarce.
Reproduction: The reproduction is dioecious, sexual, internal fertilization; viviparous. White eye orcas are polygamous, which means that they can have multiple partners in their lifetime. The maturation time of the males and females is different, for males it is 11 years, and for females it is 14 years. The females do not mate until they obtain the sexual maturity, also both sexes in order to mate, they have to be strong physically to be able to compete with other orcas. White eye orca females are able to mate several times a year, which means that the reproduction cycle is not regular. Similarly to the killer whales, white eye orcas have their own dialect, each pod has its own language, and this fact plays a huge role in the mating process, because most of them do not mate with orcas from other populations. The length of the gestation is about 12 -13 months, orcas give birth to only one offspring every time, calves are being born in the water. White eye orcas are precocial, females are significantly invested in parental duties for about a
The american water shrew also known as the Sorex palustris is the “world’s smallest warm-blooded diving species.” The american water shrew is rather large. It has a slender body covered with brownish-black fur. It has a long tail and a long pointy moveable snout. The total length of this critter can range from 130mm to 170mm, and the weight can be from 8 grams all the way to 18 grams. Both the female and male critters seem to have the same appearance but the male water shrew tends to be longer and heavier then female water shrews. The color of the critter can vary, it is generally a brownish-black color or a grayish-black or the dorsal side. On the ventral side it tends to be a silvery-grey. The color of their fur seems to change with season.
Axolotls live from 10 to 20 years. There are about 500 offspring per litter. Their main predators are birds and fish. They can be one of five different colors including black, white, pink, grey, and brown. (I personally prefer the pink ones, so much more cute) They can travel in the water
They are solitary creatures who remain submerged for most of their time at sea making difficult to study their behavioural tendencies.
When the temperature drops, animals who hibernate disappear from the outside world and emerge once again out in the open in the spring. Biologists wonder what activity occurs in the animals’ hidden underground chambers. Semi - fossorial animals dig enough suitable space underground for hibernation and movement. Woodchucks, skunks, and cottontail rabbits are known species that would occupy a den. Small mammal species like the jumping mice, meadow voles, and white footed mice are known to roam along vegetation to conceal themselves from prey. However, what is the probability that a small mammal would take the advantage and sneak right in and occupy it during the winter is a subject that interest most researchers.
Mating occurs before sunrise and mates are found by scents. When the female lays her eggs it forms a stick that contains thirty to fifty eggs. They hatch after about twenty-five days and they eat the cactus pad. After about two moths in the host cactus they exit the cactus and form cocoons. They become a pupa under the debris on the ground. Once they reach the moth stage they search for a
Texas Cichlids breed easily ("Texas Cichlid"). The female will lay eggs on top of something that is flat and the male will impregnate the eggs ("Texas Cichlid"). Before the eggs hatch, the male and female cichlids burrow a small hole ("Texas Cichlid"). The male protects the area while the female takes care of the eggs ("Texas Cichlid"). Three to five days later, the baby cichlids are born and then they spend time in the hole that was burrowed for five to eight days ("Texas Cichlid"). Once they reach a certain size, the young cichlids should be taken out of the tank ("Texas
It is protected by a brownish striped shell, this individual mussel was originally homed in Eurasia (Europe), but now can be found within our river, the St Lawrence. Zebra mussels are filter feeders which being so they reduce the amount of plankton for other species. In large quantities when eating they can clear the water up, which allows the sunlight to penetrate deeper into the Saint Lawrence. Zebra mussels don't eat certain types of plankton, which impacts other species greatly due to the toxic algal blooms. With clearer waters, light sensitive fish, like the walleye, swim to deeper waters to escape the sunlight. Many scientist to this day are concerned with the health of fish and birds who eat the zebra mussel. Meaning if we went back in our history this could of possibly never been a
