detailed fossils‚ and the influence of the fossil field on evolutionary knowledge. It was a warm summer day in 1909 when Charles Doolittle Walcott stumbled across a strange rock formation dotted with smooth rocks that he recognized as fossilized crustaceans. The Smithsonian secretary took note of them and returned to camp to share the news. Calling the discovery a “find” is an understatement. Over the following 15 years‚ Walcott made seven more trips to the site and collected over 65‚000 specimens

According to Reece et al. (2015)‚ animals can be described as organisms that are multicellular‚ heterotrophic eukaryotes that have tissues made from embryos. The difference between plants and animals are from their source of nutrients. Plants get their food by making them through a process called photosynthesis‚ which makes plants an autotroph. Animals‚ on the other hand‚ get their food by consuming other organisms and ingesting them‚ which makes them a heterotroph. Besides that‚ there are also variations

with an omnivorous diet and the ability to consume small and large prey. Daphnia and Cyclops are crustaceans often found in this species’ diet. Also‚ they help with mosquito control by feeding on mosquito larvae. The eyes of the Orangespotted Sunfish are corrected for spherical aberration‚ meaning they are a visual fish and need sight to find their prey. Since their prey is small fish and crustaceans‚ good eyesight is important to find them in the murky water that they live in. The Orangespotted

The Orangespotted Sunfish (Lepomis humilis) is often confused with other sunfishes. This species is classified in the class Actinopterygii‚ order Perciformes‚ and family Centrarchidae. One characteristic that makes them stand out from other fishes are their black and orange spots. Also‚ their operculum is lined with a solid white band. Nine to ten bars can be identified on this fish. The bars on the female have a light center‚ which is a way of gender identification when the males are outside of

P. samuelis is a detritovore‚ but will opportunistically feed upon living plants or animal matter. Unlike other crustaceans‚ hermit crabs require the shell of another organism to protect their soft abdomen‚ which is not covered by the same chitinous exoskeleton

Fishes Long- spine porcupinefish Family:Diodontidae “buteteng laot” (Diodon holocanthus) Like all species in the family Diodontidae‚ Long-spined Porcupinefish (Diodon holocanthus) can inflate themselves by swallowing water (or air). As in other species in the genus Diodon‚ this swelling causes the erection of the long movable spines covering the body. The Long-spined Porcupinefish is a robust fish with rounded dorsal and anal fins. Spines on the forehead of the Long-spined

This crustacean has an outer transparent covering called the carapace. The unique physiology of the water flea is useful in translational research allowing researchers to visibly study all of the bodily systems without causing harm to the specimen (2). Being classified
