Semua jepretan ini sebenarnya sudah cukup lama. Liburan Lebaran tahun 2013, kami sekeluarga ke Singapore dan menikmati beberapa atraksi menarik di Singapore. Salah satunya adalah S.E.A Aquarium, yang sampai tahun 2013 masih merupakan aquarium terbesar di dunia. Di tahun 2014 posisinya sudah diambil alih oleh Chime-Long Ocean Kingdom yang berada di Zhuhai, China.
Untuk saya yang paling menarik dan eksotis untuk dijepret adalah dua mahluk lautan yaitu seadragon dan jellyfish. Dua tahun sebelumnya juga pernah ditampilkan jepretan jellyfish dari Ocean Park Hong Kong – Jellyfish Dalam Lensa.
Sesuai namanya, seadragon memang berbentuk mirip naga – binatang yang entah keberadaannya memang benar pernah ada atau hanya legenda belaka. Seadragons ada tiga jenis, yaitu: leafy seadragon, weedy seadragon dan ruby seadragon. Yang ada di S.E.A Aquarium dan kebetulan tertangkap lensa adalah yang jenis leafy seadragon.
The leafy seadragon or Glauert’s seadragon, Phycodurus eques, is a marine fish in the family Syngnathidae, which includes seadragons, pipefish, and seahorses. It is the only member of the genus Phycodurus.
It is found along the southern and western coasts of Australia. The name is derived from the appearance, with long leaf-like protrusions coming from all over the body. These protrusions are not used for propulsion; they serve only as camouflage. The leafy seadragon propels itself by means of a pectoral fin on the ridge of its neck and a dorsal fin on its back closer to the tail end. These small fins are almost completely transparent and difficult to see as they undulate minutely to move the creature sedately through the water, completing the illusion of floating seaweed.
Much like the seahorse, the leafy seadragon’s name is derived from its resemblance to another creature (in this case, the mythical dragon). While not large, they are slightly larger than most seahorses, growing to about 20–24 cm (8–10 in). They feed on plankton and small crustaceans.
Jellyfish (also known as jellies or sea jellies or a stage of the life cycle of Medusozoa) are free-swimming members of the phylum Cnidaria. Medusa is another word for jellyfish, and refers to any free-swimming jellyfish life stages among animals in the phylum. Jellyfish have multiple morphologies that represent cnidarian classes including the Scyphozoa (over 200 species), Staurozoa (about 50 species), Cubozoa (about 20 species), and Hydrozoa (about 1000–1500 species that make jellyfish and many more that do not).
Jellyfish are found in every ocean, from the surface to the deep sea. Some hydrozoan jellyfish, or hydromedusae, inhabit freshwater; freshwater jellyfish are less than an inch (2.5 cm) in diameter, are colorless and do not sting. Large, often colorful, jellyfish are common in coastal zones worldwide. Jellyfish have roamed the seas for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal.
In its broadest sense, the term jellyfish also generally refers to members of the phylum Ctenophora. Although not closely related to cnidarian jellyfish, ctenophores are also free-swimming planktonic carnivores, are generally transparent or translucent, and exist in shallow to deep portions of all the world’s oceans.
Alternative names for groups of jellyfish are scyphomedusae, stauromedusae, cubomedusae, and hydromedusae. These may relate to an entire order or class.
Yang saya jepret ini adalah dari keluarga Chrysaora. Saya kurang jelas apakah ini Chrysaroa quinquechirra (Atlantic sea nettle) atau saudaranya, yaitu Chrysaora fuscescens (Pacific sea nettle) yang sedikit lebih besar.
Masih mengutip Wikipedia:
Chrysaora quinquecirrha (known as the Atlantic sea nettle or East Coast sea nettle) is a species of jellyfish that inhabits Atlantic estuaries, such as the Chesapeake Bay. It is smaller than the Pacific sea nettle, and has more variable coloration, but is typically pale, pinkish or yellowish, often with radiating more deeply-colored stripes on the exumbrella, especially near the margin.
Chrysaora fuscescens (commonly known as the Pacific sea nettle or West Coast sea nettle) is a common free-floating scyphozoa that lives in the Pacific Ocean.
Sea nettles have a distinctive golden-brown bell with a reddish tint. The bell can grow to be larger than one meter (three feet) in diameter in the wild, though most are less than 50 cm across.
The long, spiraling, white oral arms and the 24 undulating maroon tentacles may trail behind as far as 3.6 to 4.6m (12 to 15 feet). For humans, its sting is often irritating, but rarely dangerous.
Chrysaora fuscescens has proven to be very popular for display at public aquariums due to their bright colors and relatively easy maintenance. It is possible to establish polyps and culture Chrysaora in captivity. When provided appropriate aquarium conditions, the medusae do well under captive conditions.
Menikmati setiap gerakan gemulai mereka di dalam air sungguh menawan hati. Nampak magis dalam dunianya yang sunyi senyap di kedalaman samudera.
