Welcome to LegaSea Ecology

We believe one of the greatest tools to combat the climate crisis is knowledge. We are determined to create a platform with comprehensive, accessible, marine focused, educational resources that help inspire learners of all demographics to become passionate about conserving one of the worlds greatest ecosystems.

Giving season is upon us and what better gift to g

Giving season is upon us and what better gift to give than one focused on preserving the planet and marine ecosystems!? Check out our most recent article, “10 Organizations to Gift to this Giving Season” to learn about, as the title suggests, 10 organizations doing their part to better the big blue. 🌊

Navigating the climate crisis can be difficult as an individual and sometimes it is hard to acknowledge that one person can really make a difference. We challenge you to remember that each of these organizations rely on donations from people JUST LIKE YOU to make their research happen, and look at all the good they’ve been able to achieve so far because of it! 🐬

Throughout the month of November and December LegaSea Ecology will match your donations to whatever organization (or organizations) you choose. Send us a DM with proof of donation and we will send one right back.

You may have heard of ghost nets, but have you hea

You may have heard of ghost nets, but have you heard of ghost gear? Ghost gear describes any lost, discarded, or abandoned fishing gear in marine environments. Unfortunately, this gear keeps fishing long after humans have touched it, entangling marine life, smothering habitats, and contributing to the plastic pollution crisis.

It is estimated that around 640,000 tons of ghost gear including nets, lines, and ropes, enter the ocean every year! Now that is seriously spooky! 👻

Manta rays feed on zooplankton and microcrustacean

Manta rays feed on zooplankton and microcrustaceans by swimming with open mouths through the water column. They filter and ingest the plankton and then flush the remaining water out their gills.

Research conducted by Oregon State University found that the method these manta rays use to filter their food could improve our own commercial filtration systems! While commercial filtration systems often have issues with clogging, manta rays avoid this issue using an array of leaf-like lobes. As water passes over these lobes, a series of little whirlpools are created. Food particles then ricochet off and away from these whirlpools in a technique called “ricochet separation”. Because this technique repels particles rather than trapping them, it resists clogging and can operate at high flow rates.

Implementing mechanisms used in ricochet separation could allow filtration systems to be more effective and efficient, specifically in wastewater filtration and reducing microplastic pollution.

Swipe to see a quick visual as to how ricochet separation repels rather than traps food particles!

What if we told you life on reefs was made possibl

What if we told you life on reefs was made possible by a fairly unassuming organism? 🪸

Coral reefs are typically found in oligotrophic (nutrient poor) waters, which can be characterized by that iconic crystal clear blue color. Oligotrophic waters, like those found in the Indo-Pacific and Caribbean, are often referred to as marine deserts. However, coral reefs persist nonetheless thanks to a phenomenon known as the sponge loop! 🧽

Put simply, the sponge loop describes a sponges ability to uptake high levels of dissolved organic matter (DOM), and keep it in and redistribute it throughout the coral reef ecosystem!

Want to get into more detail? Check out our blog post on sponges and the sponge loop on the LegaSea Ecology website!

Did you know that tiny fish fuel life on coral reefs?

Research has found that cryptobenthic (living near the seafloor, hiding in crevices or camoflauged) fish makeup 60% of all biomass consumed in reef ecosystems.

These little fish, most of which are smaller than 5 centimeters, spend their entire life on the reef. It is thought that these fish are able to maintain their population size, despite being a significant prey species, by staying close to home. Unlike some other migrating species, by sticking close to their parents’ reef, these tiny fish have a greater chance of survival by avoiding the threats of the open ocean. This, in turn, supplies adult cryptobenthic fish populations with a steady stream of juveniles that replace each adult that is eaten!

Ampullae of Lorenzini are a system of electrorecep

Ampullae of Lorenzini are a system of electroreceptors found primarily on the head and snout of sharks, and are part of the broader lateral line system. The lateral line system, also referred to as the lateral line organ (LLO), is responsible for detecting changes in pressure, temperature, and salinity, as well as movement and vibrations throughout the water column. 🌊

Ampullae of Lorenzini are comprised of small clusters of sensory cells, called ampulla, which sit inside a jelly-filled collagen tube that then opens to a pore on the animal's skin. The conduction between the jelly-like substance and an external fluid (in this case, water!) sends all kinds of signals to the shark about its environment. 🦈

As an integral part of the LLO, ampullae of Lorenzini have the special ability to detect the electrical fields of prey species and even the magnetic field of the earth! This suggests that not only can these little pores help with prey detection, but also in shark migration and navigation! 🌎

Can you spot the ampullae of Lorenzini on this reef shark?

A West Atlantic Trumpetfish (Aulostomus maculatus

A West Atlantic Trumpetfish (Aulostomus maculatus )(back)🎺 swims alongside a juvenile Stoplight Parrotfish (Sparisoma viride) (front)🚦.

Did you know Trumpetfish utilize a hunting strategy known as "shadowing" or "shadow hunting"? In this ambush technique a trumpetfish will swim alongside or behind a large, herbivorous, fish to hide itself while moving towards unsuspecting prey. Once close enough, the trumpetfish will spring into action and use their long, tube-like mouths to suck them up! Talk about a sneak attack!
