Killifish (Fundulus heteroclitus)
Stout, olive-green fish Rounded tail
The “Chub,” well known to fishermen, can live for a day covered only with a layer of damp seaweed. It does us a real service by feeding on the mosquito larvae in brackish water.
Sticklebacks (Gasterosteus and Apeltes species)
Spines on the back Very narrow base to tail
During the early summer months, the Stickleback builds a barrel-shaped nest, held together with gelatinous threads. After the eggs have been deposited, the male guards the nest with amazing vigor, considering his size.
Sand Lance (Ammodytes americanus)
Knife-shaped body Long dorsal fin (fin on back) Protruding lower jaw
