Abstract(s)
Em qualquer mergulho na costa da Graciosa é visível a complexidade estrutural do ambiente, com pontas rochosas alternando com aglomerados de calhau ou de blocos, grutas, arcos e destroços de navios afundados. Mesmo a monotonia do fundo arenoso é quebrada por recifes e baixas. Esta multiplicidade de ambientes proporciona uma grande riqueza de nichos ecológicos. Os organismos estruturantes são as macroalgas marinhas, que exibem formas e cores luxuriantes, forrando a rocha na sua quase totalidade. Entre as algas podem encontrar-se muitas espécies de invertebrados: das vibrantes estrelas-do-mar vermelhas até aos minúsculos nudibrânquios, autênticas jóias submarinas. Sobre o fundo nadam inúmeros e coloridos peixes das várias espécies, a mansidão e abundância dos meros continuando a encantar hoje como o fizeram nos anos 60 ao Prof. Luiz Saldanha. Em zonas mais sombrias observam-se facilmente corais negros, raros noutras paragens. Nas numerosas baixas passam jamantas, tubarões e tartarugas. O litoral da Graciosa, cheio de vida, apresenta um padrão diversificado de cores e de formas que faz com que o mergulho seja sempre motivo de interesse e satisfação.
ABSTRACT: In any dive on the coast of Graciosa the structural complexity of the environment is quite visible. There are rocky peaks alternating with piles of stones or blocks, caves, arches and wrecks. Even the monotony of the sandy bottoms is broken by reefs and banks. This diversity of settings allows great riches of ecological niches. The structuring organisms are marine macro algae, displaying luxuriant forms and colours, and covering the rocks almost entirely. Among the algae many species of invertebrate animals can be found: from the vibrant red sea stars to the tiny nudibranchs, authentic underwater jewels. Over the sea bottoms, swimming, one can see countless and colorful fish of diverse species. The tameness and abundance of the groupers still cause amazement today as they did in the 1960s to Professor. Luiz Saldanha. In darker areas the black coral, rare in other parts of the world, is easily observed and in the countless banks manta rays, sharks and turtles swin by. The coast of Graciosa, full of life, presents a diverse pattern of colours and shapes wich make each dive a motive for interest and pleasure.
