Like whales, dolphins have a horizontal fluke rather than vertical tail fins like fish. ⊗ĭolphins and whales have hair and blubber - milky, white fat underneath a animal’s skin. In aquariums they have been observed making rings and other shapes with bubbles and playing with them. Bottlenose dolphins come to the surface an average of once every 28 seconds to breath. They can blow bubbles from their blowholes. When they surface dolphins inhales four to ten liters of air in one second. It is the result of a flared jawbone, which serves as an ultra-sensitive ear.ĭolphins have blowholes about the size of a quarter with inner valves and out outer valves to seal out water when the dolphin is under water. The distinct dolphin "smile" is a manifestation of the natural curve of the animal’s jawline not a friendly disposition.

Dolphins have conical teeth, a defined beak, a pronounced bulbous forehead, a more streamlined body, and a curved dorsal fin while porpoises have spade-shaped teeth, a rounded head and triangular dorsal fins. Porpoises are distinguished from dolphins in having teeth that are flat, like chisels, instead of round, like pegs. The 37 species of dolphins (32 sea-going species, 3 river species and killer whales). They include dolphins, porpoises, pilot whales, bottlenose whales and killer whales. ĭolphins, porpoises and whales are members of mammalian Cetacean family.

A 120 quart cooler – this is the minimum size I would take.Gaff – sometimes more than one – for bringing the fish aboard.Hooks for dead or live bait – usually in the 6/0 to 7/0 range in standard hooks for trolling and 7/0 circle hooks for live baiting.These leaders are usually six to eight feet in length. The reason for a wire leader is that other species than dolphin (like barracuda) may strike your bait. Leaders usually made from 50 to 70 pound test wire, or 80 pound test monofilament.Lighter spinning or casting rods and reels for shoolies near the boat.Spinning rods and matching reels in the same line class,.Matching conventional reels spooled with 25 to 30 pound monofilament line.
