The term “mojarra” is widely used in many Spanish-speaking regions, particularly in Latin America, to refer to a variety of small, silvery fish. Understanding what “mojarra” means in English can be tricky because it doesn’t translate directly to a single species. Instead, it’s a generic term encompassing several different types of fish belonging primarily to the family Gerreidae, also known as silver biddies or mojarras. Beyond this, other fish may occasionally be called mojarra depending on the region.
Understanding the Gerreidae Family: The Heart of the Mojarra
The family Gerreidae is a group of perciform fishes found in tropical and subtropical waters worldwide. They are characterized by their highly protrusible mouths, which they use to suck up invertebrates and other small organisms from the substrate. This feeding behavior is a key characteristic that unites the various species considered “mojarra.”
Physical Characteristics and Habitat
Silver biddies, or mojarras, are typically small to medium-sized fish, usually ranging from a few inches to a foot in length. They possess a compressed body shape and a silvery coloration, often with subtle patterns or markings. This silvery hue provides camouflage in their shallow water habitats.
Mojarras are predominantly found in coastal environments, including estuaries, lagoons, and mangrove swamps. They are adept at tolerating varying salinity levels, allowing them to thrive in both freshwater and saltwater conditions. This adaptability is a crucial factor in their widespread distribution and abundance. Many species are also found in brackish water.
Diet and Ecological Role
As mentioned earlier, mojarras are primarily bottom feeders, using their protrusible mouths to extract food from the sediment. Their diet consists mainly of small invertebrates, such as crustaceans, worms, and insects. They also consume algae and other organic matter.
In the ecosystem, mojarras play a significant role as prey for larger fish, birds, and marine mammals. They contribute to the food web by converting small organisms into a food source for higher trophic levels. Their abundance in coastal habitats makes them an important link in the energy flow.
Identifying Mojarra in English: Common Species and Their Names
Pinpointing the exact English name for “mojarra” requires understanding the specific species being referred to. Since “mojarra” is a general term, different species fall under this umbrella. Here are some of the most common species referred to as “mojarra” and their corresponding English names:
Spotfin Mojarra (Eucinostomus argenteus)
The Spotfin Mojarra, scientifically known as Eucinostomus argenteus, is one of the most frequently encountered species referred to as “mojarra.” Its English name is quite specific, making identification relatively straightforward.
Distinguishing Features of the Spotfin Mojarra
This species is characterized by its silvery body and a distinctive black spot on the dorsal fin. The spot is usually more prominent in juveniles and may fade slightly in adults. Spotfin Mojarras are typically found in shallow coastal waters and estuaries along the Atlantic coast of North and South America.
Silver Jenny (Eucinostomus gula)
Another common “mojarra” species is Eucinostomus gula, known in English as the Silver Jenny. Like the Spotfin Mojarra, it belongs to the Eucinostomus genus and shares many similarities.
Key Identification Points for the Silver Jenny
The Silver Jenny is also silvery in color but lacks the distinct black spot on the dorsal fin that characterizes the Spotfin Mojarra. Instead, it may have faint dusky markings. It inhabits similar coastal environments as the Spotfin Mojarra.
Yellowfin Mojarra (Gerres cinereus)
The Yellowfin Mojarra, scientifically named Gerres cinereus, belongs to the Gerres genus, which also falls under the Gerreidae family. While less commonly referred to simply as “mojarra” in some regions, it is still part of the broader group.
Differentiating the Yellowfin Mojarra
This species is identified by its yellowish fins, particularly the anal and pelvic fins. The body is silvery, and it tends to be slightly larger than the Spotfin Mojarra and Silver Jenny. It is often found in seagrass beds and around coral reefs.
Other Species Sometimes Called Mojarra
While the species mentioned above are the most common, other fish may occasionally be called “mojarra” depending on local customs and regional dialects. These may include other members of the Gerreidae family or even unrelated species that share similar characteristics, such as small size and silvery coloration.

What exactly is Mojarra in the context of Java development?
Mojarra is the reference implementation of JavaServer Faces (JSF), a Java specification for building component-based user interfaces for web applications. It’s essentially a concrete implementation of the JSF standard, providing all the necessary classes, interfaces, and functionality defined by the specification. Think of JSF as the blueprint and Mojarra as one fully constructed house built according to that blueprint.
Being the reference implementation, Mojarra serves as the standard against which other JSF implementations are measured. It’s developed and maintained by Oracle (formerly Sun Microsystems) and is often the first implementation to showcase new features and improvements defined in updated JSF specifications. This makes it a crucial component in understanding and working with JSF-based applications.
What is the primary function of Mojarra in a JSF application?
Mojarra’s primary function is to process and render JSF components within a web application. It takes care of the entire lifecycle of these components, from creating them based on the JSF view (usually defined in Facelets or JSP) to managing their state and handling user interactions. It’s the engine that drives the display and behavior of the user interface.
Specifically, Mojarra handles things like rendering HTML, processing form submissions, managing navigation between pages, and providing server-side validation. It essentially abstracts away much of the complexity of dealing directly with HTTP requests and responses, allowing developers to focus on building the user interface logic using a component-oriented approach.
How does Mojarra relate to other JSF implementations?
Mojarra, as the reference implementation, serves as the benchmark for all other JSF implementations. Other implementations, such as Apache MyFaces, must adhere to the JSF specification and are often compared to Mojarra in terms of performance, features, and stability. They provide alternative options for developers depending on their specific needs or preferences.
While different implementations exist, the core concepts and APIs of JSF remain consistent. This means that code written against the JSF specification should, in theory, be portable between different implementations with minimal modifications. However, minor differences in configuration, bug fixes, and performance characteristics may influence a developer’s choice of implementation.
What are the key benefits of using Mojarra in a Java web project?
Using Mojarra offers several key benefits. First and foremost, you’re using the reference implementation, ensuring the most complete and accurate representation of the JSF specification. This often translates to fewer compatibility issues and potentially faster access to new features as they are introduced in JSF specifications.
Secondly, Mojarra is backed by Oracle, a major player in the Java ecosystem, providing a degree of assurance in terms of long-term support and stability. It’s also widely adopted, resulting in a large community and readily available resources for troubleshooting and learning. Finally, it is highly customizable and integrates well with other Java EE technologies.
How do I include Mojarra in my Java web application?

For Maven, you would typically add a dependency to the `com.sun.faces` group with the artifact ID `jsf-impl`. The version should correspond to the specific JSF version you intend to use. For Gradle, the approach is similar, defining a dependency using the same group ID, artifact ID, and version. The build tool will then handle the process of resolving and including the Mojarra libraries in your project’s deployment.
What are some common configuration options related to Mojarra?
Mojarra’s configuration can be tailored through entries in your web application’s `web.xml` file (or its annotations-based equivalents). Common configuration options include setting the default suffix for Facelets files (usually `.xhtml`), configuring the state management strategy (e.g., client-side or server-side), and specifying the character encoding for your application.
Furthermore, you can configure settings related to resource handling, such as the location of resource libraries and the caching of resources. Debugging and performance settings, such as enabling or disabling development mode and adjusting the state saving interval, can also be configured. Proper configuration of these options is crucial for optimizing the performance and behavior of your JSF application.
