Sphoeroides camila

Sphoeroides camila is a species of pufferfish native to Brazil. [1] Previously thought to be the bandtail puffer (Sphoeroides spengleri), the species was discovered through DNA analysis. [2] The fish lives in the western Atlantic from northern to southeastern Brazil, and some may be found in the southern Caribbean. [1] [2]

Contents

Physical characteristics

Sphoeroides camila possesses several distinctive features, including at least one pair of lappets and blue spots or circles on its back. Usually, it displays 13 tear-shaped spots in a lateral-ventral row, though the number ranges from 11 to 14. The caudal fin's distal bar is wide and has a greenish-yellow hue. [2]

Habitat

Sphoeroides camila is prevalent in shallow and clear reef waters along the Brazilian coast, with depths of up to 20 meters, occasionally extending to 70 meters. It is often seen either alone, in pairs, or small groups, and multiple individuals can be found closely together, hovering over the seabed. Unlike S. spengleri, it is seldom found in seagrass beds, which distinguishes their behavior. [2]

Diet

As a generalist zoobenthivore, Sphoeroides camila feeds on a varied diet, including crustaceans, mollusks, worms, echinoderms, and zooplankton larvae. They also exhibit opportunistic foraging behavior, such as being attracted to mussels opened by a diver or chasing prey stirred up by other creatures. [2]

Behavior

These puffers are diurnal, spending their nights in reef crevices or partially buried on nearby sandy or gravelly bottoms. During this time, they expose their eyes and upper dorsum while seeking shelter. [2]

Differences from bandtail puffer

For over a century, Sphoeroides camila was mistakenly identified as Sphoeroides spengleri. The species share a morphological similarity and, together with Sphoeroides marmoratus from the Eastern Atlantic, they form a complex of closely related species known for the conspicuous lateral row of black marks. These three species share a common ancestor but, due to geographic isolation, have evolved into distinct species. [2]

Sphoeroides camila, in addition to molecular differences, exhibits several distinguishing features from S. spengleri. The new species, S. camila, typically presents at least one pair of well-developed pale lappets on its dorsum, a feature usually absent in S. spengleri. It also displays 24 to 34 lappets on the left sagittal section of its body (compared to 10 to 18 in S. spengleri). The blotches in the lateral-ventral row of S. camila are oblong and vertically tear-shaped at the midbody, while those of S. spengleri are rounded, rarely elongated horizontally. Furthermore, the distal bar of the caudal fin in S. camila is yellowish-green and covers at least 40% of the fin's length, whereas in S. spengleri, it is black and covers no more than 30% of the fin's length. [2]

These two American species also differ in their preferred habitats: S. camila is commonly found in hard substrates such as rocky and coralline reefs, while S. spengleri prefers seagrass beds. [2]

Etymology

The fish is named in honor of Camila Carvalho, daughter of the lead author. [3]

Tetraodontidae is a family of primarily marine and estuarine fish of the order Tetraodontiformes. The family includes many familiar species variously called pufferfish, puffers, balloonfish, blowfish, blowers, blowies, bubblefish, globefish, swellfish, toadfish, toadies, toadle, honey toads, sugar toads, and sea squab. They are morphologically similar to the closely related porcupinefish, which have large external spines.

<span class="mw-page-title-main">Tetraodontiformes</span> Order of fishes

Tetraodontiformes, also known as the Plectognathi, is an order of ray-finned fishes which includes the pufferfishes and related taxa. This order has been classified as a suborder of the order Perciformes, although recent studies have found that it, as the Tetraodontoidei, is a sister taxon to the anglerfish order Lophiiformes, called Lophiodei, and have placed both taxa within the Acanthuriformes. The Tetraodontiformes are represented by 10 extant families and at around 430 species overall. The majority of the species within this order are marine but a few may be found in freshwater. They are found throughout the world.

Valentin's sharpnose puffer, also known as the saddled puffer or black saddled toby, is a demersal marine fish belonging to the family Tetraodontidae. The saddled puffer is a small sized fish which grows up to 11 cm. It is widely distributed throughout the tropical and subtropical waters of the Indian Ocean, Red Sea included, and until the oceanic islands of the Pacific Ocean. It inhabits rocky and coral reefs, lagoons and external reef until 55 m. Canthigaster valentini has a diurnal activity.

<span class="mw-page-title-main">Map puffer</span> Species of fish

The map puffer, also known as the map pufferfish, scribbled pufferfish, or Kesho-fugu, is a demersal marine fish belonging to the family Tetraodontidae. The map puffer is typically found in tropical and subtropical waters from the Indian Ocean to the western Pacific Ocean. This fish contains tetrodotoxin, a potent and deadly chemical compound used to ward off predators. Despite being highly poisonous, the map puffer can be found both in the aquarium trade and certain food markets.

<span class="mw-page-title-main">Northern puffer</span> Species of fish

The northern puffer, Sphoeroides maculatus, is a species in the family Tetraodontidae, or pufferfishes, found along the Atlantic coast of North America. Unlike many other pufferfish species, the flesh of the northern puffer is not poisonous, although its viscera can contain poison, and high concentrations of toxins have been observed in the skin of Floridian populations. They are commonly called sugar toads in the Chesapeake Bay region, where they are eaten as a delicacy. There was widespread consumption of northern puffers during the rationing that accompanied the Second World War, establishing a commercial fishery that reached its zenith in the 1960s. In much of the Northeast, the fish is known simply as "blowfish" or "chicken of the sea". They may also be sold as "sea squab".

Canthigaster rostrata, commonly known as the Caribbean sharp-nose puffer, is a pufferfish from the Western Central Atlantic. The Caribbean sharp-nose puffer is a small fish with a maximum length of 12 cm or approximately 4.7 inches. It can be encountered from the coast of South Carolina to Venezuela, including Bermuda, the Gulf of Mexico, and in the Caribbean Sea. They can live up to 10 years in the wild, females typically live longer due to aggressive male territory behavior. The Caribbean sharp-nose puffer is a highly toxic species of marine fish due to the presence of tetrodotoxin in its tissues and organs. Despite its toxicity, the sharp-nose pufferfish occasionally makes its way into the aquarium trade.
