Palaemonetes paludosus, commonly known as ghost shrimp, glass shrimp, and eastern grass shrimp, [2] [3] is a species of freshwater shrimp from the southeastern United States.

Neotrypaea californiensis (formerly Callianassa californiensis), the Bay ghost shrimp, is a species of ghost shrimp that lives on the Pacific coast of North America. It is a pale animal which grows to a length of 11.5 cm (4.5 in). One claw is bigger than the other, especially in males, and the enlarged claw is thought to have a function in mating.
Feeder shrimp, ghost shrimp, glass shrimp, grass shrimp, river shrimp or feeder prawns are generic names applied to inexpensive small, typically with a length of 1 to 3 cm (0.39 to 1.18 in), semi-transparent crustaceans commonly sold and fed as live prey to larger more aggressive fishes kept in aquariums.
During surveys in 2016-2019 on Kunashir Island, 28 pairs of Blakiston's fish owls were registered. [38] In Russia, fish owls are killed by fur-trappers, drown in nets set for salmon, and are shot by hunters. [23] In Japan, death by hunting is unlikely, but fish owls have been hit by cars and killed by power lines. [33]
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Cabezon feed on crustaceans, mollusks, fish and fish eggs. There is evidence to support that juveniles and adult Cabezons feed on specific species within that age range. Only the adults show a clear seasonal change in diet. In this group, the percentage of mollusks and fish is higher in winter, and spring compared to summer and fall.
The main prey of Pel's fishing owls is fish. They can take fish weighing as much as 2 kg (4.4 lb), but most fish caught are much smaller, usually weighing 100–200 g (3.5–7.1 oz). They are not picky eaters among fish species and any fish that is in a reasonable size range and found close to the water's surface is readily caught and consumed.
