The document discusses different types of whale jumping behaviors. It notes that humpback and right whales jump the highest out of the water. When whales jump, they gain speed with their tail and lift their head and body up to look around. They land on their side to avoid hurting their stomach. It also mentions that some whales do strange jumps where they rise up and then sink back down fast. Big whales have strong skeletons, weight, and tail muscles that give them the power to leap out of the water despite their large size, with right whales jumping the highest.
The document discusses whales and how they communicate and live. It explains that whales communicate through sounds from a hole below their blowholes rather than their mouths. They can sense sound with their ears and chins. It also states that whales live in oceans, not aquariums, because they are too big. They find food in cold water and live in very cold water.
The document discusses different students' reports on their investigations into whales. One student said whales have a broad, flat tail and small wings. Another said whales have a broad tail with two parts - a solid part and a line down the middle. They move their tail side to side to turn. Whales are large because their ancestors were large land animals that adapted to the sea. Some whales can reach 30 meters long and weigh over 200 tons. Whales defecate and urinate through their genitals.
The document discusses how whales give birth and their respiratory systems. It is reported that calves are born tail first in deep waters and the mother brings the newborn to the surface to breathe. Whales breathe through a single blowhole or two blowholes located on top of their head, which brings air to their lungs. The blowholes act like a fountain, expelling water and air. Whales have small eyes and can close their eyelids in bright light and open them in low light.
The document discusses various characteristics of starfish and whales. It explains that starfish do not have hair on their skin but have spikes on their faces where barnacles attach. Some males use the spikes to fight each other. It also notes that whales have thick layers of blubber under their skin for insulation and warmth, and that they defecate like humans through an anus located between the stomach and tail.
The document discusses different types of whales and how they eat. It notes that some whales have teeth while others have baleen, and describes how each type feeds. Some feed on krill and plankton by opening their mouths and straining the food from the water using baleen. Others with teeth eat larger prey like squid and shrimp. The document also mentions that some whales are blue or gray on top and lighter colored below, while others are black on top and white or gray below.
The document summarizes discussions from students about whales. Daniela said whales are very big, with hearts as large as cars, tongues like elephants, and tails like small planes. Clara explained there are whales with and without teeth or beards, and that gray whales can jump well. Oriol discussed different whale types like blue whales, sperm whales, gray whales, and killer whales. He also noted whales used to live on land long ago before evolving to live in water. Marta, Araceli, and Pol then described whale mouths, explaining they have very large mouths and tongues, some have teeth while others do not, and they have beards or baleen used to eat small fish.
Los estudiantes visitaron el centro L'Escola del Mar el 23 de abril de 2008, donde observaron los huesos de ballena y los acuarios que contienen diferentes especies marinas.
This document contains an index of topics that students in a class called "Les Estrelles de Mar" will cover in their project about whales. The index includes questions about whales' appearance, including how their mouth, teeth, baleen, tongue, tail, fins, nose are and how they are used. It also includes questions about whales' abilities like breathing, heart, skin, spots on their face, offspring, caring for calves, families, diet, excretion, communication, habitats, and keeping whales in aquariums.
This document appears to be an index in Catalan for a student project about whales. It lists questions about where whales live, what they eat, if they eat seagulls, if they have teeth and beards, how they eat, what color they are, how their eyes are, how baby whales are born, how they get water out, if small whales get water out, how their tail is, how their fins are, why they are so big, how much they weigh, if they go to the bathroom, if they jump, how they jump, why they are so strong, and if they have "goals".
This document discusses searching for information and who can help find it. It mentions looking at whales from a rock, going underwater to see whales, and looking at whales on the ocean floor. The document also states that help could come from one's father.
3. L’ EMMA ENS HA DIT QUE LES BALENES PODEN VIURE A QUALSEVOL LLOC DEL MAR.
4. Viuen en bandades, i efectuen generalment grans migracions; durant l'estiu viuen a les mars fredes, polars o subpolars, i durant l'hivern a les temperades, on neixen els balenons, els quals, com que no tenen una capa adiposa tan desenvolupada com els adults (fins a 50 cm de gruix en alguns casos) no suportarien les baixes temperatures de les aigües polars. Els adults, mentre habiten a les mars cà lides, no s'alimenten, ja que en aquestes mars no hi ha l'abundor de plà ncton que troben a les polars. LA MIREIA ENS HA DIT QUE VIUEN A L’AIGUA FREDA. DE VEGADES, QUAN FA CALOR, VAN A VIURE A UN LLOC ON L’AIGUA SIGUI MÉS FREDA.
6. Ìý LES BALENES ES DIVIDEIXEN EN DOS GRANS GRUPS: BALENES AMB DENTS O BALENES SENSE DENTS.Ìý ÌýÌýÌýÌýÌý LES BALENES AMB DENTS MENGEN PRINCIPALMENT CALAMARS, POPS I PEIXOS PETITS; LES DENTS ELS SERVEIXEN PER ATRAPAR I O DEIXAR SORTIR LES PRESES, JA QUE SE LES EMPASEN SENSE MASTEGAR. ÌýÌýÌýÌýÌý DINTRE D’AQUEST GRUP HI SON LES ORQUES, ELS DOFINS, LES MARSOPES O EL CATXALOT.Ìý ÌýÌýÌýÌýÌýÌý LES BALENES SENSE DENTS TENEN UNES BARBES AL COSTAT DE LA BOCA QUE ELS SERVEIX PER ATRAPAR EL PLÀNCTON, EL QUAL ESTÀ FORMAT PER ANIMALETS PETITETS I PLANTES MARINES MOLT PETITES. ÌýÌýÌýÌýÌýÌý DINTRE D’AQUEST GRUP HI HA LA BALENA DE GRENLÀNDIA, ELS RORQUALS, LA BALENA BLAVA O LA BALENA GRIS. LES ORQUES PODEN MENJAR PINGÃœINS, FOQUES, PEIXOS GRANS I GAVINES QUE ES POSIN A L’AIGUA. EN DANIEL ENS HA DIT QUE MENGEN CALAMARS GEGANTS, POPS I PEIXOS. LES QUE NO TENEN DENTS TAMBÉ PEIXOS. LES ORQUES MENGEN PINGÃœINS ,FOQUES I PEIXOS. SI S’ALLUNYA MOLT, LI DÓNA UN COP MOLT FORT AMB EL MORRO O LA CUA I LLAVORS ES MENJA LA FOCA.
7. EN DAVID ENS HA DIT QUE MENGEN UNES GAMBES PETITES QUE ES DIUEN KRILL, TAMBÉ PLANCTON. LES BARBES DEL DARRERE NO SÓN IGUALS QUE LES DEL DAVANT. LES ORQUES SALTEN AMB EL CAP AMUNT I MENGEN PINGÜINS.LES BALENES NO MENGEN PEIXOS
