Estos dos enormes ejemplares de Morena Gigante son característicos del Mar Rojo. En otros mares las morenas son más pequeñas tanto en grosor como en largo. Estas miden entre 2.40 y 3.00 m cada una. Se encuentran entre 4 y 50 m de profundidad. Las Morenas Gigantes se distinguen por una cabeza amarillo-amarronada con pequeños puntos oscuros y una gran mancha oscura en la abertura de las branquias. Los adultos tienen manchas aleopardadas en todo el cuerpo. Los dientes de la mayoría se disponen en dos hileras en la mandíbula inferior y en el paladar se ubican de forma irregular. Son depredadores nocturnos alimentándose de pequeños peces, cangrejos y hasta pulpos.
These two huge samples of Giant Morey are charachteristic of the Red Sea. These ones are between 2.40 and 3.00 m long each. They are from 4 to 50 m depth. Giant Moreys are distinguished by a yellow-brown head with small dark spots and a large dark patch at the gill opening. Adults have a leopard like spotting all over the body. In most of them the teeth are disposed in two rows in the jaws and in an irregular row on the roof of the mouth. They are nocturnal pedrators feeding on a variety of reef fishes, crabs and even octopus.
This is a generally lonely fish. In this photo we can see a male, the female is nearly always yellow and less atractive. It is very common in the Red Sea. The pectoral finn seems to be tored as seen in the photo, nevertheless, it is long reaching up to the end of the tail. It feeds on small invertebrates, crabs and shrimps. They are found from 4 to 40 m depth.
Los Frailecillos Enmascarados son peces por lo general solitarios, aunque en época de reproducción pueden encontrarse en grupos más o menos numerosos. Por lo general son tranquilos e indiferentes, pero en tal época pueden ser agresivos llegando a morder con el aditivo de que su mordida es venenosa. Este video fue tomado en plena época de reproducción.
The Puffer Masked Fish is generally lonely, although in reproductive season they can be found in groups. They are generally calm and indiferent to the diver but during this season the may become rather aggresive to the point of biting and its bite is poisonous. This video was taken in reproductive season.
PEZ GATILLO TRIGGER FISH
The Trigger Fish has a beautiful shape and colour, (bright dark blue). It keeps jealous care of its eggs which are put on/in the sand. Its territory is an inverted cone whose top is towards the nest. It doesn't mind when the diver goes past over its nest without stopping, if the diver stops, it attacks. The attack consists on a warning, and the second step a bite. (According to my personal experience, don't stop). It's a very agile, fast moving fish. Its finns remind of veils.

El Misterio del Tiburón Ballena The Mystery of the Whale Shark
Este gigante de los mares, se desplaza gentilmente en busca de plancton. Sí, se alimenta sólo de plancton. No es fácil encontrarlos en los buceos, pero si hay plancton en el mar mientras buceamos, prestamos mucha atención a los habitantes submarinos que nos rodean. Esta foto fue tomada por mi amiga Pat en Maldivas en febrero 2008. Ambas deseábamos ver un tiburón ballena. Pues ella logró ver 4 en ese viaje, al cual yo no fui, y vio otro más en Sharm a principios de julio 2008, viaje al que tampoco pude ir.... Y POR ESO LA ENVIDIO.....Nadie sabe con certeza dónde se reproducen estos gigantes. Se sumergen a enormes profundidades a donde el buceador sólo puede llegar con un submarino apropiado.
This giant of the seas gently moves looking for plankton. Yes, they feed on plankton only! It's not easy finding them while diving, but when there is plankton around, we must pay full attention to the submarine inhabitants around us. This photograph, was taken in Maldives by my friend Pat in February 2008. We both wished to see a whale shark. Well, she saw 4 in that trip, to which I couldn't go, and she saw another one in Sharm beginning of July 2008, trip to which I didn't go either... THAT'S WHY I ENVY HER..... Nobody knows for certain, where this giants reproduce. They dive huge depths, where the diver can only get to, in an appropriate submarine.
Descubriendo el Mundo Submarino Discovering Submarine World
Uno de los misterios que me gustaría descubrir del Mundo Submarino, es el "orgullo" y elegancia de las Rayas Águila. ¿Cómo saben ellas que nos fasacina observar sus danzas? ¿Porqué, al vernos, se reúnen en grupos y comienzan a danzar? Una vez, en Isla de la Juventud, Cuba, nos detuvimos a unos 30mts de profundidad a observar a una de ellas que estaba a unos 40mts. Alzó su vista, nos miró, y como por arte de magia, aparecieron otras 3 de ellas y comenzaron una danza en la que estuvieron varios minutos girando en un círculo perfecto. Luego, una de ellas, salió del mismo y las demás la siguieron, desapareciendo por el mismo lugar por el que habían aparecido. ¡Fascinante y perfecto!
One of the mysteries of the Submarine World I'd love to discover, is the "pride" and elegance of the Eagle Rays. How do they get to know that watching them dance fascinates us? Why do they begin to dance when they realize we are watching them? Once, in Isla de la Juventud, Cuba, we stopped at 33mts. depth to watch one of them which was at about 45mts. or more. She looked at us, and as if by magic, another 3 eagle rays appeared and began a dance in which they circled perfectly for several minutes. Then, one of them, went away followed by her dance partners, disappearing through the same part where they had appeared through. Fascinating and perfect!
