Yellow bullhead

Description

The yellow bullhead (Ameiurus natalis) is a species of bullhead catfish that is a ray-finned fish that lacks scales. The yellow bullhead is a medium-sized member of the catfish family. It is typically yellow-olive to slate black on the back and may appear mottled depending on its habitat. The sides are lighter and more yellowish, while the underside of the head and body are bright yellow, yellow white, or bright white. The rear edge of its caudal fin is rounded. The anal fin is much longer than those of other bullheads, having anywhere between 24 and 27 rays. The yellow bullhead, though less common, can be easily distinguished from the brown bullhead and black bullhead by the group of white barbels or "whiskers" under its chin. Yellow bullheads are medium-sized bullheads rarely getting larger than 2 lb (0.91 kg) but can reach up to 6.375 lb (2.892 kg). Yellow bullheads range in size from 6 to 14 inches, and can live up to 12 years. The yellow bullhead is a voracious scavenger that will almost eat anything. It locates prey by brushing the stream bottom with its barbels. Taste buds on the barbels tell the yellow bullhead whether or not contact is made with edible prey. They typically feed at night on a variety of plant and animal material, both live and dead, most commonly consisting of worms, insects, snails, minnows, clams, crayfish, other small aquatic organisms, plant matter, and decaying animal matter. Compared to black and brown bullheads, yellow bullheads consume more aquatic vegetation. Yellow bullhead are bottom dwellers, living in areas with muck, rock, sand, or clay substrates. Its habitat includes river pools, backwaters, and sluggish current over soft or mildly rocky substrate in creeks, small to larger rivers, and shallow portions of lakes and ponds. Their habitat can vary from a slow current with poorly oxygenated, highly silted, and highly polluted water to a more swift current with clean and clear water that has aquatic vegetation. Fishermen often find them in sluggish creeks and rivers with a gravel bottom. Yellow bullhead range throughout the central and eastern US from central Texas, north into North Dakota, and east through the Great Lakes region to the East Coast. They have also been introduced to the West and can be caught as far up as northern Washington state.
