The ocean sunfish is a very large, oddly shaped fish that gets its name from his habit of floating on its side, at the sea surface, warming itself in the sun. Adults are consumed by orca, sharks[18] and sea lions. Historically, ocean sunfish were uncommon in the Gulf of Maine. Geographic Range. They are actually the heaviest bony fish species in the world (a number of sharks are heavier, but they are cartilaginous fish.) The huge ocean sunfish mola has a silvery color and gritty skin texture with speckled patterns. 2009, Dewar et al. Watanabe and Sato 2008, Nakamura and Sato 2014, Nakamura et al. [26], Many areas of sunfish biology remain poorly understood, and various research efforts are underway, including aerial surveys of populations,[44] satellite surveillance using pop-off satellite tags,[21][44] genetic analysis of tissue samples,[21] and collection of amateur sighting data. The scales of M. tecta are distinct from the other molids in that the raised conical mid-points of the scales are set far apart from each other.. Cartamil, D.P. While they're not picky eaters, they are known to specifically target Jellyfish. Doyle, D.W. Sims, N. Queiroz et al. The ocean sunfish is also known as the common sunfish, as there are three other species of sunfish that live in the oceanthe slender mola (Ranzania laevis), the sharp-tailed mola (Masturus lanceolatus), and the southern ocean sunfish (Mola alexandrini).The sunfish group gets its name for the fish's characteristic behavior of lying on its side at the sea surface, seemingly basking in the sun. [21] [45] A decrease in sunfish populations may be caused by more frequent bycatch and the increasing popularity of sunfish in human diet. However, a young specimen at the Monterey Bay Aquarium increased in weight from 26 to 399kg (57 to 880lb) and reached a height of nearly 1.8m (5ft 11in) in 15 months. They have wider anal fins than most other Sunfish, with darker roots that turn paler towards the edges.

Sunfish can be as tall as they are long when their dorsal and ventral fins are extended. Biol. They're mostly a shiny silver color, with a green or blue metallic sheen on their backs. Scales of M. alexandrini are rounded when small (29-51 cm TL) becoming more rectangular at larger sizes (>120 cm), Mola tecta (hoodwinker sunfish) image credit:https://academic.oup.com/zoolinnean/article-abstract/182/3/631/3979130. [27] Mola mola has since become a permanent feature of the Open Sea exhibit. Wood, The Guinness Book of Animal Facts and Feats. Ocean sunfish have been spotted along Acadia National Park's coastline more frequently in recent summers, fascinating tourists and locals alike. Unlike eels, shad spend most of their lives in saltwater. Marine Biology 158(3): 531540. [18] Mola genotypes appear to vary widely between the Atlantic and Pacific, but genetic differences between individuals in the Northern and Southern hemispheres are minimal. It very much looks like a fish head combined with a tail, as the rest of its body is entirely flattened. Young sunfish school for protection, but this behavior is abandoned as they grow. Eventually, the fish can be taught to respond to a floating target to be fed,[58] and to take food from the end of a pole or from human hands.[27]. In the tropics, M. mola solicits cleaning help from reef fishes. The Ocean sunfish is also on display at the Denmark Nordsen Oceanarium. M. alexandrini is found in both temperate and tropical waters.

They are known to reside in the southern hemisphere, with most records from South America, South Africa, Australasian waters and New Zealand. Sunfishes are thought to consume abundant, shallow medusae in warmer months and rely on deeper, vertically migrating gelatinous prey during cooler months, explaining the seasonality of their deep-sea excursions. Resembling a big floating blob, the ocean sunfish, or mola, is the world's largest bony fish. [12], The mature ocean sunfish has an average length of 1.8m (5ft 11in) and a fin-to-fin length of 2.5m (8ft 2in). 2011, Potter and Howell 2010) while in the Eastern Atlantic, sunfish tagged off the UK moved south to Spain to the Gulf of Cadiz (Sousa et al. Sunfish off South Africa move offshore but dont exhibit substantial latitudinal migrations (Hays et al.

Mar. . [10], The genus Mola belongs to the family Molidae. When a giant sunfish ( Mola alexandrini) surfaced last December near Faial Island in the Azores archipelago in the Atlantic, the dead animal weighed in at nearly 6,050 lbs. It has an average adult weight of 1,000 kg (2,200 lb). Recent tagging studies have finally laid to rest the historical characterization of sunfishes as passive drifters (Pope et al. This structure is formed by the convergence of the dorsal and anal fins,[22][23] and is used by the fish as a rudder. [5][25] One of the most frequent ocean sunfish parasites is the flatworm Accacoelium contortum. In August, ocean temperatures near Acadia have been recorded to reach highs of 58 F with some records as high as 63 F. This is well within the preferred range of ocean sunfish. A member of the order Tetraodontiformes, which also includes pufferfish, porcupinefish, and filefish, the sunfish shares many traits common to members of this order. [16][37], Sunfish fry, with large pectoral fins, a tail fin, and body spines uncharacteristic of adult sunfish, resemble miniature pufferfish, their close relatives. Second, discarded plastic bags pose a significant threat to ocean sunfish. A group of fishermen sailing near Norfolk Canyon, about 80 miles off the Virginia Beach coast, reeled in the catch of a lifetime: a rare deep-sea opah. The ocean sunfish, Mola mola, or common mola, is the heaviest known bony fish in the world. Tagging studies have revealed that sunfish make daytime excursions to the deep-sea, as far deep as 884 meters for Mola mola (Potter and Howell 2011) and 1,112 meters for Mola alexandrini (Thys et al. This photo was submitted to Your Shot, our photo community on Instagram. 2016). Weng, M. Erdmann and J. Tresnati. Ranzania laevis is the smallest of mature adult sunfishes, reaching only approximately 74 cm in total length (Bloch and Schneider 1801). Additionally, R. laevis is less deep-bodied than other sunfishes, is oblong in shape, and has elongate pectoral fins. The maximum size is up to 3.3m (10ft 10in) in length,[12][15] Also known as ocean sunfish, the weird fish without a tail appears to be missing the back half of its body, as if cut off behind its fins.

Dec. 13, 2021 [17], The spinal column of M. mola contains fewer vertebrae and is shorter in relation to the body than that of any other fish. Watanabe, Y. and K. Sato. In the Eastern Pacific, individuals tagged in Central and Southern California migrate as far as southern Baja California during the fall and winter months (Thys et al. (2007). These vertical movement patterns are consistent with diel vertical migration patterns and are likely linked to prey abundance and distribution. Ontogenetic shift in foraging habit of ocean sunfish Mola mola from dietary and behavioral studies. a median extension) than Mola mola. [28], In temperate regions, drifting kelp fields harbor cleaner wrasses and other fish which remove parasites from the skin of visiting sunfish. [5] Sunfish eggs are released into the water and externally fertilized by sperm. 2016). In contrast to its huge size, it has a vertebrae column of only 0.5 in (12 mm) in length.
