Mahi-mahi have compressed bodies and one very long dorsal fin extending from the head almost to the tail fin. Mature males have distinctive "foreheads"; it grows as the fish matures and often protrudes well above the body proper, which is streamlined by the musculature of the back. This "hump" is a sexually dimorphic feature; females have a ...
Mandarinfish lack scales and have a layer of smelly and bitter slime which blocks out disease and probably discourages predators, implying their bright coloration is aposematic. [63] Anglerfish have loose, thin skin often covered with fine forked dermal prickles or tubercles, but they do not have regular scales. They rely on camouflage to avoid ...
Dolphin safe labels attempt to reassure consumers that fish and other marine products have been caught in a dolphin-friendly way. The earliest campaigns with "Dolphin safe" labels were initiated in the 1980s as a result of cooperation between marine activists and the major tuna companies, and involved decreasing incidental dolphin kills by up ...
The bottlenose dolphin is a toothed whale in the genus Tursiops.They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. [3] Molecular studies show the genus contains three species: the common bottlenose dolphin (Tursiops truncatus), the Indo-Pacific bottlenose dolphin (Tursiops aduncus), and Tamanend's bottlenose dolphin (Tursiops erebennus).
A common bottlenose dolphin (Tursiops truncatus). A dolphin is an aquatic mammal in the clade Odontoceti (toothed whale).Dolphins belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and possibly extinct Lipotidae (baiji or Chinese river dolphin).
Bow-riding and other play with boats is common. In the eastern Pacific, the dolphin is often found swimming with yellowfin tuna (hence the problem with dolphin deaths caused by tuna fishing). However, they do not feed on that fish. In fact, the two species have similar diets of small epipelagic fish.
The common dolphin (Delphinus delphis) is the most abundant cetacean in the world, with a global population of about six million. [3] Despite this fact and its vernacular name, the common dolphin is not thought of as the archetypal dolphin, with that distinction belonging to the bottlenose dolphin due to its popular appearances in aquaria and the media.
The pompano dolphinfish (Coryphaena equiselis) is a species of surface-dwelling ray-finned fish found in tropical and subtropical waters. They are one of only two members of the family Coryphaenidae, the other being the mahi-mahi or common dolphinfish. [2] Pompano dolphinfish have a lifespan of three to four years.
