She wants to win the contest, but she doesn't want to lose her best friend. She loves humor, history and exploring new ways to tell a story. Frieda's books have been nominated for international awards, earned critical praise, and have been featured in magazines and newspapers around the world, including The London Times, The Observer and The New York Times. Frieda lives in Toronto, Ontario. She thinks that seven is going to be the best age to be. Her friend Jake is going to teach her to ride a two-wheeler.

And her party is going to be fabulous. That is, until Violet starts spreading stories. Kate goes right on with her planning, but she is worried.

When Violet is the only one to show up on the big day, Kate thinks that her worst fears have come true. Her grandmother shows her exactly how to make the den for the dog and how to be ready when the puppies come out. After they are born, Elizabeth helps Elsie care for them. Most important of all, though, she helps her grandmother find just the right home for each, especially the very last one.

She lives and writes in Port Rowan, Ontario. He defeats hiccups. He trades his mother for a new hat. He skillfully avoids math. And thanks to his special Flutter Kick, he easily advances to the next level -- in swimming and in life! Bruno is ready for any challenge as he learns all there is to know about being a boy. But Jake soon learns that bringing home an invisible pirate can be a real disaster, particularly when the pirate is mortally terrified of his teenage sister. There are many rules of the sea, and Captain Kidd's own cabin boy, Richard Barleycorn, teaches Jake how to face his biggest fear, Boris Baxter, the meanest boy in the whole school.

She lives in Vancouver, British Columbia, with her husband and two children in a small cottage by the sea. Leseprobe lesen Web-Ansicht. Examples of body language include leaping out of the water, snapping jaws, slapping the tail on the surface and butting heads. Lacking vocal cords , they produce sounds using six air sacs near their blow hole. Each animal has a uniquely identifying, frequency-modulated narrow-band signature vocalization signature whistle.

Researchers from the Bottlenose Dolphin Research Institute BDRI , based in Sardinia Italy have now shown whistles and burst pulsed sounds are vital to the animals' social life and mirror their behaviors. The tonal whistle sounds the most melodious ones allow dolphins to stay in contact with each other above all, mothers and offspring , and to coordinate hunting strategies.

The dolphins emit these strident sounds when in the presence of other individuals moving towards the same prey. The "least dominant" one soon moves away to avoid confrontation. Other communication uses about 30 distinguishable sounds, and although famously proposed by John Lilly in the s, no "dolphin language" has been found. However, Herman , Richards, and Wolz demonstrated comprehension of an artificial language by two bottlenose dolphins named Akeakamai and Phoenix in the period of skepticism toward animal language following Herbert Terrace's critique.

Cognitive abilities that have been investigated include concept formation , sensory skills, and mental representations. Such research has been ongoing since the s. This includes: acoustic and behavioral mimicry, [56] [57] comprehension of novel sequences in an artificial language , [58] [59] memory , [60] monitoring of self behavior, [61] discrimination and matching, [60] [62] comprehension of symbols for various body parts, [63] comprehension of pointing gestures and gaze as made by dolphins or humans , [64] [65] mirror self-recognition , [66] [67] and numerical values.

At least some wild bottlenose dolphins use tools. In Shark Bay , dolphins place a marine sponge on their rostrum , presumably to protect it when searching for food on the sandy sea bottom. Sea otters are the only other known marine mammalian tool users. A study showed mothers most likely teach the behavior to their offspring, evincing culture behavior learned from other species members. Mud plume feeding is a feeding technique performed by a small community of bottlenose dolphins over shallow seagrass beds less than 1 m in the Florida Keys in the United States.

The behavior involves creation of a U-shaped plume of mud in the water column and then rushing through the plume to capture fish. Along the beaches and tidal marshes of South Carolina and Georgia in the United States, bottlenose dolphins cooperatively herd prey fish onto steep and sandy banks in a practice known as "strand feeding". Groups of between two and six dolphins are regularly observed creating a bow wave to force the fish out of the water. The dolphins follow the fish, stranding themselves briefly, to eat their prey before twisting their bodies back and forth in order to slide back into the water.

Some Mauritanian dolphins cooperate with human fishermen. The dolphins drive a school of fish towards the shore, where humans await with nets. In the confusion of casting nets, the dolphins catch a large number of fish as well. Intraspecies cooperative foraging has also been observed. These behaviors may also be transmitted via teaching.

Controversially, Rendell and Whitehead have proposed a structure for the study of cetacean culture. Near Adelaide , in South Australia, three bottlenose dolphins 'tail-walk', whereby they elevate the upper part of their bodies vertically out of the water, and propel themselves along the surface with powerful tail movements. Tail-walking mostly arises via human training in dolphinaria. In the s, a female from the local population was kept at a local dolphinarium for three weeks, and the scientist suggests she copied the tail-walking behavior from other dolphins.

Two other wild adult female dolphins have now copied it from her. A study conducted by the University of Chicago showed that bottlenose dolphins can remember whistles of other dolphins they'd lived with after 20 years of separation. Each dolphin has a unique whistle that functions like a name, allowing the marine mammals to keep close social bonds. The new research shows that dolphins have the longest memory yet known in any species other than humans.

Petersburg FL, exhibit a rare form of self-decoration and social object use called grass-wearing. Self-decoration by wearing grass appears to be an attention-getting device rather than purely play and varies from a single blade to large clusters of grass. Grass-wearing behavior among these dolphins is a local behavioral tradition that could constitute a cultural difference from other communities. Some researchers theorize mammalian intelligence correlates to the number of nerve cells neurons in the cortex of the brain.

The bottlenose dolphin has a single blowhole located on the dorsal surface of the head consisting of a hole and a muscular flap. The flap is closed during muscle relaxation and opens during contraction. They can store almost twice as much oxygen in proportion to their body weight as a human can: the dolphin can store 36 milliliters ml of oxygen per kg of body weight, compared with 20 ml per kg for humans.

This is an adaptation to diving. Dolphins can breathe while "half-asleep". During the sleeping cycle, one brain hemisphere remains active, while the other hemisphere shuts down.

    Both sexes have genital slits on the underside of their bodies. The male can retract and conceal his penis through his slit. Females have two mammary slits, each housing one nipple , one on each side of the genital slit. The breeding season produces significant physiological changes in males. At that time, the testes enlarge, enabling them to hold more sperm.

    Large amounts of sperm allow a male to wash away the previous suitor's sperm, while leaving some of his own for fertilization. Also, sperm concentration markedly increases. Having less sperm for out-of-season social mating means it wastes less. This suggests sperm production is energetically expensive. Males have large testes in relation to their body size.

    During the breeding season , males compete for access to females. Such competition can take the form of fighting other males or of herding females to prevent access by other males. Mating occurs belly to belly. Newborn bottlenose dolphins are 0. The calf suckles for 18 months to up to 8 years, [98] and continues to closely associate with its mother for several years after weaning. She cites studies showing these dolphins as adults are inseparable, and that early bonds aid protection, as well as in locating females.

    Female bottlenose dolphins have to expend additional energy in carrying out parental care, e. Dolphins don't physically hold their infants but line up in an echelon position with infants swimming beside them. This position creates a change of water flow pattern from the infant which minimizes separation between the mother and infant, but also increases the mother's surface area and creates a drag for the swimmer. This also leaves less energy to use in swimming speed, foraging, and predator evasion.
