Tara Oceans Expeditions - May 2011. The ocean sunfish, Mola mola, or common mola, is the heaviest known bony fish in the world. It has an average adult weight of 1,000 kg (2,200 lb). The species is native to tropical and temperate waters around the globe. It resembles a fish head with a tail, and its main body is flattened laterally. Sunfish can be as tall as they are long when their dorsal and ventral fins are extended. Sunfish live on a diet that consists mainly of jellyfish, but because this diet is nutritionally poor, they consume large amounts in order to develop and maintain their great bulk. Females of the species can produce more eggs than any other known vertebrate.[1] Sunfish fry resemble miniature pufferfish, with large pectoral fins, a tail fin and body spines uncharacteristic of adult sunfish. Adult sunfish are vulnerable to few natural predators, but sea lions, orcas and sharks will consume them. Among humans, sunfish are considered a delicacy in some parts of the world, including Japan, the Korean peninsula and Taiwan. In the EU, regulations ban the sale of fish and fishery products derived of the Molidae family. Sunfish are frequently, though accidentally, caught in gillnets, and are also vulnerable to harm or death from encounters with floating trash, such as plastic bags. A member of the order Tetraodontiformes, which also includes pufferfish, porcupinefish and filefish, the sunfish shares many traits common to members of this order. It was originally classified as Tetraodon mola under the pufferfish genus, but it has since been given its own genus, Mola, with two species under it. The ocean sunfish, Mola mola, is the type species of the genus. Punta Vicente Roca, Isabela, Galapagos; EcuadorTara Oceans Expeditions - May 2011.

The Bottlenose (or Bottle Nosed) dolphin (Tursiops truncatus) in the Galapagos cooler pelagic waters tend to be larger than their cousins who inhabit warmer, shallower waters. Those in colder waters have a fattier composition more suited to deep-diving. Adults range in length from 2 to 4 metres (6 to 13 feet) and weigh from 150 to 650 kilograms (330 to 1430 pounds). Males are longer and heavier than females. The lifespan of the female Bottlenose Dolphin is about 40 years, whereas males rarely live more than 30 years.Wolf Island; Galapagos; EcuadorTara Oceans Expeditions - May 2011.

Tara Oceans Expeditions - May 2011. Salp aggregation containing small shrimps (symbiosis?). A salp (plural salps) or salpa (plural salpae or salpas) is a barrel-shaped, planktonic tunicate. It moves by contracting, thus pumping water through its gelatinous body. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton. Salps are common in equatorial, temperate, and cold seas, where they can be seen at the surface, singly or in long, stringy colonies. The most abundant concentrations of salps are in the Southern Ocean (near Antarctica). Here they sometimes form enormous swarms, often in deep water, and are sometimes even more abundant than krill. Over the last century, while krill populations in the Southern Ocean have declined, salp populations appear to be increasing. The chain of salps is the aggregate portion of the life cycle. The aggregate individuals are also known as blastozooids; they remain attached together while swimming and feeding, and each individual grows in size. Each blastozooid in the chain reproduces sexually (the blastozooids are sequential hermaphrodites, first maturing as females, and are fertilized by male gametes produced by older chains), with a growing embryo oozoid attached to the body wall of the parent. The growing oozoids are eventually released from the parent blastozooids, then they continue to feed and grow as the solitary asexual phase, thus closing the life cycle of salps.Tara Oceans Expeditions - May 2011.
